5 IMPORTANT SAFETY INFORMATION There are no user serviceable parts inside the videophone. Access to the inside of this unit should only be carried out by approved service personnel.! Keep the videophone away from water and other liquids (except when cleaning, as directed below). If you suspect that liquid has entered the equipment, immediately disconnect the unit from the ISDN and from the mains supply, ensuring first that your hands and the mains outlet area are dry. Do not use the videophone again until it is thoroughly dry. Clean the case only with a soft, lint-free cloth, either dry or slightly dampened with water. Disconnect the power and the ISDN cables before using a damp cloth to clean the videophone. Before connecting any equipment that was not supplied with the videophone, check the specification of the connectors for compatibility (see page 61). Do not use the videophone during a thunderstorm. There is a small risk of electric shock from a lightning strike. To avoid possible damage to the videophone, disconnect the power and ISDN cables during thunderstorms. Do not use the videophone if you suspect a gas leak. Operation of any electrical equipment can generate sparks which may ignite the gas and cause an explosion. Do not let cables trail where they might cause someone to trip or pull the videophone onto the floor. Use only on a stable surface. The videophone may be damaged if it falls. Do not place any part of this equipment in your mouth. Keep the equipment and its packaging out of reach of small children. Do not push objects into the ventilation slots. Do not block the ventilation slots as this could cause the equipment to overheat and malfunction. Do not use it on a soft surface such as a bed which might block ventilation slots. Do not place the videophone in direct sunlight. Do not point the camera (or any external camera) directly at the sun as this is likely to cause serious damage. Do not use the videophone in a situation where failure to perform could pose a threat to health or life. The videophone will not function in the event of a power cut. It should not be relied upon as the only means of contacting the emergency services. 1

6 Connection to the mains supply Never overload mains power sockets. In order to remove mains power from this product, you must disconnect the power plug from the mains supply socket outlet. In order to safely achieve this action, the product must be installed close to the mains supply socket outlet and be positioned in such a way that user access to the mains plug and socket connection is not restricted. The product must only be used with the provided power supply. This power supply has been extensively tested for use with the product, use of an alternative power unit may invalidate any international type approval relating to the product. If the power unit, cable or plug becomes damaged, contact the dealer for a suitable replacement. There are no serviceable parts inside. Disconnect the mains supply before attempting to handle a damaged power supply unit or damaged mains cable or plug. Any attempt to open the power unit is likely to expose a potential electric shock hazard. 2

7 1 1 Getting started Setting up your videophone and making your first calls are quick and easy. This chapter describes very briefly how to connect up your videophone and start making calls. To get the best from your videophone you should also read the rest of this User Guide as soon as you have time. To help you choose which bits to read first, the final section of this chapter shows you where to find information on specific topics. 3

8 Unpacking Unpack the videophone, retaining the packaging for future use. Check that you have received all the following items: videophone, handset and handset cord (The videophone is supplied with a protective plastic film over the LCD screen. This should be peeled off and discarded.) power supply unit and power cable ISDN cable service and warranty card this User Guide Quick Start Guide(s) SCART to Phono adaptor and Phono lead If anything is missing, contact the dealer who supplied the videophone. Connecting the equipment 1. Read the Safety information in the front of this manual. 2. Connect the handset Plug the handset cable into the handset socket on the base of your videophone (phone symbol in the diagram below). 3. Connect the ISDN cable Plug one end of the ISDN cable into the ISDN socket on the base of the videophone (LINE, right), and clip the cable into the channelling to emerge smoothly at the back. Plug the other end into your ISDN S-interface socket. 4

9 4. Connect the power supply Plug the power supply cable into the POWER socket on the back of the videophone. Then use the power cable to connect the power supply to the mains. If the mains outlet has a switch, switch it on. 1 VIDEO OUT - outputs to a TV or VCR Set TV type using AUX Audio/Video menu POWER Input from videophone power supply VIDEO IN - inputs include Camera or VCR Configures automatically for PAL and NTSC using AUX Audio/Video menu AUDIO IN - inputs include Lineaudio, VCR, Camcorder, Microphone Setup using AUX Audio/Video menu DATA - for Service Centre use only AUDIO OUT -whenin Handsfreemodeoutputstoa TV, VCR or Amplifier Note that it is normal to leave the videophone switched on all the time. However, if you do wish to disconnect it for any reason, always switch the power off at the mains before unplugging the power cable or the ISDN cable from the phone. When the indicator light on the videophone is green and the Status Bar (at the bottom of the screen) shows Ready, the phone is ready to make and receive calls. 5

10 Stand-by mode The videophone has a power-saving stand-by mode in which the screen is switched off after a few minutes without activity. It will automatically wake up if there is an incoming call, if you lift the handset, or if you press one of the buttons. Videophone set-up In most cases the videophone is ready to use without further set-up. However you may need to make a few changes to the ISDN set-up or choose a different language for the on-screen text. ISDN set-up You will not need to change the default ISDN settings unless you are outside the UK. If you need to change the ISDN settings, refer to page 39. Changing the language If you want to change the language used for on-screen prompts and messages, refer to page 39. 6

11 2 2 Making Calls Speech calls and video calls This videophone can make and receive ordinary speech calls and various types of video calls: You make and receive ordinary telephone calls (speech calls) just as you would on any normal telephone. You can make a video call to (and receive calls from) virtually any other ISDN or Highway videophones or video conferencing system. This is almost as simple as making a speech call - just press the Video Call button before dialling. 7

12 The following table shows the different types of calls you can make and receive, and for each type indicates the number of ISDN B channels used and the type of equipment that you can call. Type of call Uses Calls to / from Speech call Voice only 1B Voice phones, including ISDN and ordinary analogue phones. Standard digital (2 channel) video call (H.320) Half-rate digital (1 channel) video call (H.320) Voice and video (Best quality) Voice and video * 2B 1B H.320 videophones or video conferencing equipment * Reduced quality video compared with 2B standard digital video calls. The videophone automatically detects the type of an incoming call and handles it accordingly. See Answering calls on page 12 for details. 8

13 Manual dialling Making a speech-only call (ordinary telephone call) 1. Lift the handset or press Handsfree. A dial tone is heard and the Speech Call screen appears: 2 2. Type in the number using the number buttons. 3. The Status Bar shows the progress of the call. When the far end phone is answered you can talk to the other person, just like on a normal telephone. 4. At the end of the call, replace the handset or press Handsfree again to end the call. As with any ordinary telephone it is essential that you end any speech call you make. The call is not terminated when the other person hangs up, only when you do. 9

14 Making a video call 1. Press Video Call. The Video Call screen appears: 2. Type in the first (or only) number: If you make a mistake you can use the Left arrow button to go back and correct it. If you press OK at this stage the videophone will dial a half-rate video call. To dial a standard-rate video call you must fill in the second number. 3. Press the down arrow to move into the second box. The first number is copied into the second box: 10

15 4. If necessary, change this number. If the videophone you are calling uses the same number for both channels you do not need to change the second number. If it uses different numbers for the two channels, use the Left arrow button to move back and change the second number: 2 5. Press OK to dial. The Status Bar messages show the first channel calling, and then, when the far end answers, connecting. The second channel then automatically calls and connects. You and the person you are calling can now see and hear each other. It is common for this process to take 20 seconds. 6. At the end of the call, replace the handset or press Handsfree again to end the call. Making a half-rate (1B) video call Proceed as for a standard video call but press OK after entering only one number instead of two. Don t forget that the video quality on a half-rate video call will not be as good as on a normal video call. 11

16 Redialling The Redial button re-dials the last number you dialled, whether that was a speech call or a video call, and whether you dialled it manually or via the Phonebook. The number is briefly displayed for your information before dialling. Answering calls When a call arrives the videophone rings and displays the number on the Incoming Call screen. If the incoming number is listed in the Phonebook, the name is displayed on screen as well as the number. Auto-answer and Privacy options The videophone can be set to answer incoming calls automatically, so that you don t have to press OK. You can also set up your videophone so that video calls start off in voice-only mode, allowing you to decide when you wish to turn on the video. See the Preferences menu in Chapter 6, Setting up your videophone for details of both options. or (If in stand-by mode, the videophone will automatically wake up.) 1. Lift the handset or, to use handsfree, press OK to answer the call. The Status Bar messages show the call connecting and you are connected to your caller. (If you don t want to answer the call, you can either leave it to ring until the caller hangs up, or press Cancel to terminate the call immediately.) Ending calls If you are using the handset, simply replace the handset. If you are using the phone handsfree, make sure that the handset is in its cradle, then press Handsfree. As with any ordinary telephone it is essential that you terminate any speech call you make. A speech call dialled by you is not terminated when the other person hangs up, only when you do. Check for the Ready message on the Status bar to be sure the call is terminated. 12

17 Using the Phonebook The Phonebook has 100 memories for you to store your most frequently used numbers so that you can dial them more easily. The memories are indexed from 0 to 99. You can store any kind of number (speech or video) in a Phonebook memory, with a name to identify it. Dialling from the Phonebook 1. Press Phonebook to display the first 10 entries currently stored in the Phonebook: 2 Speed dialling You can dial one of the first 10 entries even quicker using the Speed Dial facility, as long as you know the which entry it is: Simply hold down the digit (0 9) for a couple of seconds and the corresponding Phonebook entry will be dialled automatically 2. If the entry you want is not shown, use the Left and Right arrows to page through the Phonebook, 10 entries at a time, to find the right page. 3. Use the Up and Down arrows to select the entry you want to dial. 4. Press OK to dial the number. The call then proceeds exactly as if you had dialled the number manually. 13

18 Storing a number in the Phonebook 1. Press Phonebook to display the first page of 10 entries currently stored in the Phonebook. 2. If necessary, use the left and right arrow keys to move through the Phonebook, a page at a time. Use the up and down arrow buttons to select an empty memory slot, then press Phonebook again. An empty screen for a speech call appears: 3. If you want to store a speech number or an analogue video number, go straight to Step 4. To store a digital video number, press Video Call. The screen changes to one for a video call: Wrong call type? If you accidentally start entering a video number into a Speech Call screen, or a speech number into a Video Call screen, simply press Video Call to change the call type to the one you want. 4. Type in the name, using the letters on the number pad: While you are typing in the Name box, the number buttons change their behaviour so that you can enter letters: When you press a particular button it enters the first of the letters shown above the digit. Each time you press the button, the character entered cycles through the letters, first in upper case then in lower case, followed by the digit on the button, then any accented letters. The 1 button allows you to enter punctuation such as hyphens, brackets, etc. When you have selected the correct letter, press the Right arrow to move on to the next position. To enter a space, press the Right arrow. If you make a mistake, use the Left arrow to go back and correct it. 14

19 5. When the name is complete, use the down arrow to move into the number box(es) and enter the number(s). Enter the numbers in the same way as for manual dialling, i.e. two numbers (which may be the same) for a standard video call, or a single number for a speech call, half-rate video call or analogue video call. 6. Press OK to store the entry, or Cancel if you want to discard it. Once you have stored a new number, you return to the main list in the Phonebook. From here you can either dial a number by selecting it, or continue to enter or modify entries in the phonelist. Either press OK to dial the number, or press Cancel if you don t want to make a call. 2 Changing an entry in the Phonebook Proceed exactly as for storing a new entry, but instead of an empty slot, select the entry you wish to change. Then press Phonebook again. To delete the existing information: Use the Left arrow to delete backwards one character at a time Use Shift followed by the Left arrow to delete the whole line. 15

21 3 Features 3 This chapter introduces the different components of the videophone: The videophone s components 17

22 The camera The built-in camera is situated above the screen of the videophone. Lens cover Attached to the back of the case is a plastic lens cover which you can fit over the front of the camera if you do not want to be seen. This provision is a legal requirement in some countries. You can also set up your videophone not to send video calls until you choose to do so. [Preference setting Vid Off, Chapter 6]. You can adjust the focusing and the tilt of the camera manually. These adjustments are best done with the large Self-view image visible, so that you can see what effect your changes are having. Press the Self-View button repeatedly until the large Self-view image appears. Make the adjustments as follows: Turn the focusing collar around the lens to bring the image into focus. Tilt the camera head up or down to compose the shot. The brightness and contrast settings are controlled with the Set Video button, see page 27. For help with connecting an external camera refer to page 32. Button names Throughout this manual, the feature buttons are referred to using the button label underlined (e.g. Press Video Call to make a video call ). The secondary function on a button, accessed using Shift, is referred to in the following way: e.g. Press Call Status (Shift Self-View) to hide / show the Status Bar. Feature buttons Notice first the Shift button at top left. This is like the Shift key on a typewriter, calculator or computer: it is used to activate the secondary function of another button. The label below each button shows its main function, while the label above, if there is one, shows the secondary function that is invoked by using Shift. To make it easy to use, you don t have to hold the Shift button down while you press the second button. When you press Shift, an upward-pointing arrow appears on the Status Bar ( ), telling you that the videophone is in Shift mode and waiting for you to press a second button. When you press the second button the arrow disappears, telling you that it is no longer in Shift mode. Each of these features is described elsewhere in this User Guide, but briefly they are: Shift Access secondary functions (labels above buttons), also: Change colour scheme (Shift number) Set-Up Set up the videophone - see page 38. Phonebook Open the Phonebook - see page

23 Video Call Handsfree Cancel Make a video call If no call is in progress: Make a handsfree call; During a call: Switch from handset to handsfree operation, or clearing a handsfree call. Cancel or abort the current action. Self-View Aux Set Audio Set Video Move/remove the Picture-in-picture self-view Switch between Main and Auxiliary camera (see page 32). Change the audio settings, including speaker volume, ringer volume, etc. Change the video settings, including screen brightness and contrast, viewing angle, etc. 3 Redial Recall Mute Audio Re-dial the last number dialled Recall button, for use with PBXs only Mute the outgoing audio - press again to undo Mute. Functions using the Shift key Call Status Restore Settings Show or hide the Status Bar Restore the default audio / video settings 19

24 Other buttons Number buttons Arrow buttons When dialling, enter digits; During calls, generate tones; When editing the Phonebook, enter digits and letters. Left and right arrows decrease and increase the speaker volume. Up and down arrows change the screen brightness. When changing audio and video settings, these arrows increase and decrease slider values. When navigating the menu system these arrows move around the screen. OK Confirm current action. In particular, dial the number entered. The video screen The video picture is shown on the colour LCD screen (and on any TV, monitor or other display that is connected, see page 31). As well as displaying the image of your caller, certain parts of the screen are used to display extra information, including a self-view image, call status and other information about the state of the videophone: 20

25 Using self-view to adjust the video settings Because the Self-view shows the brightness, contrast, etc. of the image you are sending, you can use it to help you adjust these video settings to give a good quality image. The Self-view image automatically pops to the half screen central position while you are adjusting settings. Note that while there is no call in progress the Self-View image comes directly from the camera and does not accurately represent the frame rate and resolution you are able to send. During a call the image shown gives a better representation of the video quality seen at the far end. Self-view image The Self-view image shows the picture your camera sees. During video calls this is what the person at the other end sees. Like the Picture-in-Picture feature on some TVs, it is a small image set into the main image. You see your caller s picture on the whole screen, with an image of yourself. The Self-view image is reversed, so that you see yourself as if you were looking in a mirror. This makes it easier for you to compose yourself in front of the camera. The person you are calling sees the picture the right way round though, so they will be able, for example, to read any text you show them, even though you see it reversed in the self-view image. There are four small self view positons in each corner of the screen plus a half screen, a full screen self view, and an off (i.e. hidden). Each time you press the Self-View button the Self-view image moves to a new position, cycling through the sequence. All self view images are mirrored except for the full screen self view. If a videocall is made with the full screen self view, the self view image automatically changes to a small self view so that you may see the received video image. Note that this behaviour is changed if you are using the Status bar Hide option within the Preferences menu. When Hide is selected, once a call connects, the Status bar disappears and any full screen self-view is automatically hidden. 3 21

26 The Status Bar The Status Bar at the bottom of the screen gives you information about each call you make. It is normally displayed at the bottom of the screen, although you can remove it if you wish, by pressing Call Status (Shift Self-View). While a call is being established the left-hand side shows a series of messages indicating the progress. During the call it shows the length of the call so far, in hours and minutes (HH:MM). The right-hand side shows one or more symbols to help you keep track of the state of the videophone: A figure 1 and a figure 2 show the state of the two ISDN channels. (Both figures are shown only for calls that use both B-channels, i.e. standard rate digital video calls.): Calling Connected and negotiating with the far-end videophone Fully connected An upward pointing arrow is displayed when the Shift button has been pressed and the videophone is waiting for a second button. A telephone handset or a loudspeaker indicates whether you currently have the handset or handsfree selected. When sound waves are shown beside it you should be able to hear something from the earpiece or loudspeaker. A telephone with a lifted receiver indicates that Auto-answer (see page 42) is enabled. A + sign (which may be combined with the handset or loudspeaker symbol) indicates that the auxiliary audio and video inputs are selected (see page 28). 22

27 On-screen symbols Certain important information is shown by symbols at the sides of the screen. You can not remove these symbols while they are active. Outgoing audio is muted see page 25. Outgoing video is frozen or off see Freezing video on page 25 and Vid Off on page 42. Colour scheme You can choose from 10 different colour and transparency schemes for the on-screen text, Status Bar, dialog boxes, etc. Try them all to see which you prefer. 3 To change the colour scheme, press Shift followed by a digit (0-9). 23

28 Menu Layout Press Set-up to access the Configuration menu of the videophone. The navigation pathway for all menus off the Configuration menu is shown in the diagram below. mm215 Videophone typical Menu structure 24

29 Mute Audio and Freeze Video Many ordinary telephones have a Mute button which turns off the microphone, so that you can still hear the person you are calling but they can not hear you. The Mute Audio and Freeze Video buttons on the videophone are similar: When you press Mute Audio your caller can no longer hear you although you can still hear them. A microphone symbol with a cross appears on screen to remind you that you are muted. To cancel mute, simply press Mute Audio again. The audio mute symbol disappears to confirm that you are no longer muted. When you press Freeze Video you freeze the image you are sending. A video screen symbol with a cross appears on screen to remind you that you are not sending live video. 3 Muting It is good practice to warn the person at the other end when you are about to mute audio or freeze video. The still image you are sending sharpens up over a couple of seconds, making this a good way to show your caller something detailed such as text or an intricate object. To start sending video again, simply press Freeze Video again. The video off symbol disappears to confirm that you are now sending live video again. Switching between handset and handsfree You can switch between the handset and handsfree at any point during a call by pressing the Handsfree button. Remember: If you switch to the handset while the handset is in its cradle, the call will be terminated. (In fact this is the correct way to hang up a handsfree call.) So if you don t want to end the call, make sure you lift the handset before you press Handsfree. 25

30 Audio and video settings The audio and video set up of the videophone is controlled by two buttons, Set Audio and Set Video. Each buttton controls a number of functions, accessed by toggling through the selection. Set Audio controls Audio volume, Audio Gain, Ring volume and AutoAnswer rings. Set Video controls View Angle, Brightness, Contrast, Saturation, and Hue. Each function is displayed on screen as you select it. Change the settings using the arrow keys, then press OK to accept the changes. External audio levels The Audio Volume and Audio Gain settings also affect AUDIO OUT and AUDIO IN respectively. See Audio-visual connectors in Chapter 7 for more information. Restore Settings to system defaults The videophone is delivered with all settings at reasonable default values. You can restore the audio and video settings to these default values at any point by pressing Restore Settings (Shift, Set Video). Audio settings Settings shortcut The arrow buttons provide a shortcut for changing the most commonly adjusted audio and video settings. (This can be convenient during a call, when you do not want to see the slider bar and value): The Up and Down arrow buttons adjust the View Angle setting. While the videophone is ringing for an incoming call, the Left and Right arrow buttons adjust the Ring Volume setting. At all other times they adjust the Audio Volume setting. Audio Volume Audio Gain Ring Volume AutoAns Rings The volume of the loudspeaker. (The volume of the handset earpiece is fixed: it is not affected by adjustments to this setting.) The sensitivity of the microphone. This affects the volume of the sound you send to the other end. (The sensitivity of the handset microphone is fixed: it is not affected by adjustments to this setting.) The volume of the ringer. (Note that setting the ringer volume to minimum is not the same as turning it off. See the Preferences menu, page 42, if you want to do this.) AutoAns Rings sets the number of times the videophone will ring before it automatically answers an incoming call. AutoAns Rings will only work if Auto Ans is enabled. This is done via the Preferences menu, page 42). 26

31 Video settings Screen viewing angle Like all LCD displays, the screen has a much narrower range of viewing angles than a normal TV screen. If you are too far to the side or too high you will not see the picture properly. View Angle Vertical viewing angle of the screen. You may need to adjust this if you change your sitting position or stand up. Adjusting the View Angle video setting has the same effect as physically tipping the videophone screen up or down. If the screen appears either too dark or too bright it is likely to be caused by a poorly adjusted View Angle. High and Low resolution High and low resolution are also known as CIF and QCIF resolution respectively. Brightness Contrast Saturation Hue Frame Rate The brightness of the picture you send to the far end. The contrast of the picture you send to the far end. The colour saturation of the picture you send to the far end. The hue of the picture you send to the far end (NTSC cameras only). The maximum number of frames per second of video sent to the far end: A high frame rate (more frames per second) gives smoother movement but can result in loss of detail. Conversely, a low frame rate gives a clearer image, but can appear jerky. 3 Some videophones can only encode and decode QCIF video, and you only see low resolution images when talking to these phones. Resolution This setting takes one of two values: High (352 x 288 pixels) or Low (176 x 144 pixels). It affects the resolution of the picture you send: High resolution gives a more detailed image than Low, but Low resolution permits a higher maximum frame rate, giving a more responsive but less detailed picture. Generating tones As on many phones, the number buttons generate tones when pressed which can be used during speech calls and digital video calls to access tone-operated menus and other automated services. Recall (Flash) If you are connected to a suitable exchange, the Recall button lets you use exchange features, such as call forwarding, during speech calls. See the documentation for your exchange for details. 27

32 Using external audio-visual equipment Your videophone has connectors on the back allowing you to connect additional audio-visual equipment [Chapter 4]. To simplify the use of a second camera, microphone and display, or a VCR, you can set up a second audio-visual configuration, then switch seamlessly between the main (default) configuration and this auxiliary configuration at the press of a button. Each audio-visual configuration comprises four items: PAL and NTSC PAL and NTSC are different international TV standards. Most video equipment supports one (or sometimes both) of these standards. Countries using NTSC include North America, most of South America, Japan and Taiwan. Video In Audio In TV type Cam type This can be either the built-in camera or the VIDEO IN connector. This can be either the built-in microphone, the AUDIO IN connector, or both of these mixed together. Connect video equipment TVs, VCRs, etc. of either type to the videophone, but you must set up the videophone to match, so that it outputs video in the correct format. Normally set to PAL for use in Europe. To configure the Auxiliary Audio visual equipment Refer to the the Main and Aux Audio/Video menus on page 44 for details about setting up the main and auxiliary configurations. Switching between the Main and Auxiliary audio-visual configuration When the videophone is first powered up it uses the Main audio-visual configuration, which by default uses the built-in camera, microphone and LCD screen. 1. To switch to the Auxiliary audio-visual configuration, press the Aux button on the videophone. The videophone immediately switches to the audio-visual configuration you defined. (The picture may take a second or two to stabilise.) When you are using the Auxiliary audio-visual configuration the Status Bar shows a plus sign (+) as a reminder. To switch back to the Main audio-visual configuration, press Aux again. 28

33 4 Connecting other equipment This chapter describes how to connect extra equipment to your videophone, including: 4 Audio-visual equipment TV set Second camera Video recorder (VCR) External connectors VIDEO IN This connector can be used for any Composite video source, such as a second camera or a VCR. It operates as an alternative to the built-in camera. Use the Main and Aux audio-visual configurations and the Aux button to select between the two. VIDEO OUT This connector can be used for any Composite video equipment, such as a TV set or a VCR. It operates in parallel to the built-in LCD screen: the picture appears on both. You will need to set the TV Type (PAL or NTSC) in the Main and Aux audio-visual configurations to match the equipment you connect. 29

34 AUDIO IN This connector can be used for any Line audio source, such as a VCR or a camcorder microphone. Use the Main and Aux audio-visual configurations and the Aux button to select whether or not this input is active. When active it operates in parallel with the built-in microphone: When you are using handsfree the microphone and AUDIO IN inputs can be mixed together or separately selected; when you are using the handset, this input does not operate. AUDIO OUT This connector can be used for any Line audio equipment, such as a TV set, VCR or amplifier. It operates in parallel with the built-in speaker. When the handset is in use, this output does not operate. POWER This connector is only for use with the power supply provided. 30

35 TV auxiliary inputs Most modern TVs have Auxiliary inputs (also known as composite video inputs), which are usually either two phono connectors (Audio and Video), or a single SCART connector. There is usually an AUX button on the TV and/or remote control to allow you to select the auxiliary inputs instead of the normal signal. If in doubt, consult the user guide supplied with the TV. Connecting a TV set Connecting your videophone to a TV set allows you to see the video picture on the TV screen and hear the sound from your TV loudspeaker. You can use the TV set as an alternative to the built-in screen and speaker, or use both at the same time. Connecting the TV to the videophone You will need a TV with audio and video inputs (either phono connectors or a SCART connector). Using the cable provided, connect one end of the cable to the TV, and the other end to the AUDIO OUT and VIDEO OUT sockets on the videophone Be careful to connect video to video and audio to audio. Setting up the audio-visual configuration Check that the TV Type is set to PAL (for Europe) or NTSC (for USA and Canada) in both the Main Audio/Visual menu and in the Aux Audio Visual menu. If this is set incorrectly, the picture may be distorted. Using the TV Turn on the TV and select its Auxiliary audio-visual input. You will see the videophone picture on the TV screen as well as the videophone screen. When you use the videophone handsfree, the sound will come out of the TV speaker as well as the videophone. When you use the handset, the TV will be silent. 4 31

36 Connecting a second camera You can connect a second camera (such as a camcorder) to the videophone as an alternative or addition to the built-in camera. During calls use the Aux button to switch between the two cameras. Connecting the videophone to a second camera Read any instructions provided with your camera and follow them when connecting the equipment. 1. Connect the camera s video output to the videophone s VIDEO IN. 2. If the camera has a built-in microphone that you want to use, connect the camera s audio output to the videophone s AUDIO IN. 3. Go to the Set-Up menu and select Aux Audio/Video. Check (and if necessary change) the Video In option to Ext Cam and the Audio In option to Line In or Mix Mic. Muting It is good practice to warn the person at the other end when you are about to mute audio or freeze video. If you don t they may think something has gone wrong with their equipment 4. Connect the camera s external power supply if it has one, and switch on the camera. 5. Switch to the Auxilliary setting to select the external camera by using the Aux key and position the self view image. 6. In the Aux Audio/Video menu, set the values as follows: Video In Ext Cam Audio In TV Type Line In (the camera s built-in microphone) Mixed (both microphones mixed together) or Int Mic (if the camera has no built-in microphone). Should match the setting in the Main Audio/Video section. Switching between cameras 1. Press Aux to switch to the second camera. 2. Press Aux again to switch back to the Main camera. 32

37 Connecting a video recorder (VCR) With a VCR connected to the videophone you can play pre-recorded video clips, including the soundtrack, to the other end during a video call. Recording calls You can also use a VCR to record a video call: Connect AUDIO OUT and VIDEO OUT to the VCR s audio and video inputs and set the TV Type to match the type of the VCR. If you have a self-view image visible that will also be recorded; however, the sound track will not include your side of the conversation. Because AUDIO IN can be mixed with the built-in microphone, you can speak over the video soundtrack and continue talking to the person at the far end while you play the clip. Connecting the videophone to a VCR You will need a pair of standard phono cables. 1. Connect the VCR s audio and video outputs to the videophone s AUDIO IN and VIDEO IN respectively. Setting up the Aux audio-visual configuration Press Set-up to access the Configuration menu, then select the Aux Audio/Video menu. 2. Set Video In: Use the external camera. 3. Set Audio In: If you want to talk at the same time as the video is playing, use Mixed. If not, use Line In. 4. Also check that the TV Type is correct for the display you are using. Playing the video clip 5. Press Aux to select the Auxiliary audio-visual configuration. The person at the far end sees a blank screen or snow from the VCR. If you selected Mixed audio in Step 3 they can still hear you; if you selected Line in they can no longer hear you. You can still see and hear the far end normally. 6. Press PLAY on the VCR to start playing the clip. The person at the far end sees and hears the video clip. If you selected Mixed audio in Step 3 you can continue talking to them while the clip is playing; if not, they will just hear the video soundtrack. When the clip has finished 7. Press Aux again to select the Main audio-visual configuration. The person at the far end sees you again. Press STOP on the VCR. 33 4

39 5 Getting the best from your videophone There are a few steps you can take when setting up your room and using the videophone to ensure that you get the best results: Lighting As with conventional photography, correct lighting is vital to achieving the best results from your videophone. 5 Make sure your face is well lit, preferably from the front, and avoid having lights behind you that might shine into the camera lens. Remember that you can adjust the camera brightness, contrast, etc. but beware that extreme settings will adversely affect the quality of the picture you are sending. If in doubt use the default settings. Movement Too much movement tends to slow down the frame rate of the video, resulting in a jerky picture. Avoid having a lot of movement in the background for example, don t sit with your back to a corridor and try not to move around excessively. This doesn t mean you have to sit completely still: just move naturally, but be aware that if you wave your arms around the person you are calling may see a jerky picture. Remember too that a small movement near the camera is just as bad as a big movement at a normal distance. 35

40 If you have something very detailed to show, you can send a clear still image using the Freeze Video button, see page 25. Sound Where possible, it is better to choose a quiet environment than a noisy one. In very noisy situations you will find the handset more effective than handsfree. When using handsfree, remember that the built-in microphone is at the front right-hand corner of the case. Don t cover this with your hand, or tap on the videophone case. You can control the volume of the sound you are sending by adjusting the sensitivity of the microphone (see Audio Gain, page 26). However, unless you are sitting particularly close to or far from the microphone it is best to leave this at the default setting and let the person at the other end adjust the volume to suit their own surroundings. Before making a call Use the Self-view image to check that the camera is pointing where you want it to and that it is in focus. If necessary, adjust the camera brightness, contrast, etc. to give a good picture. The default audio and video settings should be suitable for most situations, and you will probably only need to make a few minor adjustments, in particular to the Audio Volume and View Angle, to suit your surroundings. Beware of making big changes to the settings. It is possible, for example, to change the camera settings and the screen settings together so that the self-view picture looks fine to you, but the picture you send to your caller is either too dark or too light. One way to avoid this is to call another videophone that you know is correctly set up, adjust your speaker volume and screen viewing angle to give good results, then leave these settings alone and adjust the camera brightness, contrast, etc. to give a good self-view image. 36

41 6 Advanced Settings You can customise your videophone to suit your needs: If the default ISDN settings do not match your network, you will need to change them before making a call. You can select a different language for the screens and messages. You can set up the videophone to automatically answer incoming calls, and change its default behaviour. If you have an extra camera, display and/or microphone connected you can define an auxiliary audio-visual configuration so that you can easily switch between this extra equipment and the default equipment. You can adjust the positioning of the on-screen text so that it is centred on your display. 6 A diagram of the menu structure is shown on page 24, which will help you in setting up your videophone to suit your needs. 37

42 Changing the set-up - Configuration menu 1. Press Set-Up to display the main set-up menu: 2. Use the Up and Down arrows to move the pointer to the menu you want to change, then press OK to display the current values. The different menus are dealt with individually on the following pages. 3. Use the Up and Down arrows to move the pointer from one field to the next. 4. To change any field, press the Right arrow repeatedly to cycle through the available options and find the one you want. 5. When you have finished changing fields, press OK to store those changes (or Cancel to discard them). The values are stored and you are returned to the set-up menu. 6. Move the pointer to select another section, or, to leave the set-up system, select Exit and press OK. 38

43 Installation menu The Installation menu alows you to control the language settings, ISDN configuration, network restrictions and H.263 video interworking parameters Language You can change the language used for all on-screen text. H.261 and H.263 The H.320 standard supports two different methods for encoding video, called H.261 and H.263. In general, H.263 gives better results at low bandwidths. However, H.263 is not as well established as H.261, and some videophones do not yet support it properly. You may experience difficulty using H.263 with these phones and will need to use H.261 instead. Where the videophone is able to detect such problems it will automatically switch to using H.261 for the current call. If this fails it will release the call and change the H.263 set-up item to Disable, so that all future calls use H.261. However, these measures are not foolproof and you may need to change the H.263 set-up item yourself. Unless you experience difficulties, we recommend leaving this item set to Auto. ISDN Although ISDN is an international standard, in practice there are small but important differences in the way it has been implemented in different countries. Your videophone will be set to use an appropriate variant for the country in which it was sold, but you may need to choose a different variant if your network is non-standard. If you are not sure which variant your network uses, your ISDN provider will be able to tell you. If you change the ISDN setting the new value will not come into effect until the videophone is restarted. As long as there is no call in progress the videophone will automatically restart when you press OK. This takes a few seconds. Restrict Most ISDN networks operate at 64 kbit/s on each B-channel, but some, known as Restricted networks, operate at only 56 kbit/s. This is becoming less common, but does still occur on some networks in the USA. H.263 Controls the use of H.263 video encoding: Auto The videophone automatically uses the most appropriate video-encoding standard (H.261 or H.263) for the circumstances. 6 Disable The videophone uses H.261 at all times. 39

44 ISDN Profile menu This menu allows you to set up Service Profile IDs (SPIDs) or Multiple Subscriber Numbering (MSN) for your videophone. SPIDs are only required by certain ISDN networks, principally in the USA. If your ISDN provider has not given you any SPIDs then it is probably safe to assume that you do not need to use them. If you do need SPIDs you will not be able to make any calls until you have set up the SPIDs and the corresponding Directory Numbers in the videophone. Multiple Subscriber Number MSN allows several pieces of equipment to share a single ISDN line. The line is assigned a block of numbers, and each piece of equipment connected to it is allocated one or more of these numbers. When an incoming call arrives on the line, only the equipment whose allocated number matches the number that was dialled will respond. You can allocate up to two MSN numbers to your videophone. MSN is a supplementary service offered by some ISDN suppliers. Unless you have requested this service for your line, you will not need to set up MSN. If you are using MSN your videophone will receive all incoming calls on the line (rather then the subset intended for you) until you set up the MSN number in the videophone. Do not enter any information in this section unless you need to use SPIDs or MSN. If you store a new MSN or SPIDs the new values will not come into effect until the videophone is restarted. As long as there is no call in progress the videophone will automatically restart when you press OK. This takes a few seconds. 40

45 Setting up SPIDs SPID 1 / SPID 2 You must fill in both boxes, even if both SPIDs are the same. The SPID(s) associated with your first / second directory numbers. Directory Numbers(s) The directory number is the number dialled by a caller in order to reach your ISDN line. When you move into the SPID 2 box the first SPID is copied in automatically. If you have a single directory number and SPID you do not need to change this value. If you have two SPIDs, use the Left arrow to move back and change this value. Local Number 1 / Local Number 2 You must fill in both boxes, even if both numbers are the same. The local directory number(s) of your ISDN line (i.e. omitting any national or area codes). When you move into the Local Number 2 box the first number is copied in automatically. If you have a single directory number you do not need to change this value. If you have two numbers, use the Left arrow to move back and change this value. Setting up Multiple Subscriber numbers (MSN) SPID 1 / SPID 2 Leave both these boxes blank. 6 Local Number 1 / Local Number 2 In Local Number 1, enter the number to be associated with the videophone. You can enter the whole Local Number (i.e. omitting any national or area codes) or just the digit(s) from the end that distinguish it from other equipment on the same line. If you want to associate a second number with the videophone, enter this in Local Number 2. Otherwise, leave Local Number 2 blank. 41

46 Preferences menu Use the Preferences menu to define the way the videophone is setup. Calls can be answered automatically, the video/audio can be set on or off, The ringer can be set a number of ways, and the sleep mode delay set. If an external camera is connected, use Cam Ctrl to set it how you wish, while H.324 Mode defines the way speech calls are converted to analogue. Auto Ans This item lets you set the videophone to automatically answer incoming calls, so that you don t need to lift the handset or press OK to accept a call. The value VidOnly enables auto-answering for incoming video calls, but not speech calls. Remember that if you leave the videophone in auto-answer mode it will answer incoming calls even when you are not there. Whilst this may be useful for video calls, it is unlikely to be appropriate for speech calls. Vid Off This item controls whether or not you are immediately visible to the other person at the start of a video call. Some people for example prefer to answer incoming calls in a speech-only mode, then switch on the video pictures once they know who is calling them. There are four possible values: CallIn CallOut All None Video is initially off when you answer incoming calls, but not when you make outgoing calls. Video is initially off when you make outgoing calls, but not when you answer incoming calls. Video is off at the start of all calls, both incoming and outgoing. Video is active at the start of all calls. 42

47 Aud Off You can also mute audio at the start of calls. You might choose to do this on video calls if you don t need sound for example, deaf or hearing-impaired callers using sign language because doing so frees up the maximum amount of resource for video, improving the quality. There are two possible values: None VidOnly Audio is active at the start of all calls. Audio is off at the start of all video calls (incoming and outgoing), but active for speech-only calls. Ringer You can select a different ringer sound to use for incoming calls. The videophone demonstrates each sound to help you choose one. One of the available values is Off, which means that there will be no audible ring. If you choose this value beware that unless you are watching the video screen you may not notice when an incoming call arrives, and if you have Auto-answer enabled (see Auto Ans on the previous page)the call could even be connected without your noticing. You can also adjust the volume of your chosen ringer, by changing the Ring Volume audio setting. Status Status controls the presence or absence of the Status bar on screen, and controls the way that pop-up messages are displayed. The options are On and Hide. The Hide option ensures that the status bar and pop-up messages do not interfere with the image on screen. (see Self View, page 21.) 6 On Hide The status bar is visible at all times, and informational pop-up messages appear and typically disappear after about 8 secs. Since the status bar shows the call duration this is the recommeded option. With Hide selected, when a video call is initiated, the status bar is visible. Once the call is connected, the Status bar disappears, and no informational pop-ups appear. When the call is released, the status bar re-appears. Sleep This is the length of time the videophone will wait before going into stand-by mode if it has not been used. 43

48 The Main and Aux Audio/Video menus These two menus allow you to define your Main and Auxiliary audio-visual configurations, which you will be able to switch between using the Aux button. See Auxiliary audio-visual configuration on page 28 for more details. The options displayed in the diagrams are the system defaults. Video In The video input to be used: Int Cam Ext Cam Built-in camera Camera/VCR connected to VIDEO IN Audio In The audio input to be used: Int Mic Line In Mix Mic Built-in microphone Audio source connected to AUDIO IN Built-in microphone and AUDIO IN mixed together TV Type The format of the video displayed on the built-in screen and any equipment connected to VIDEO OUT. May be either PAL or NTSC. Note that if the wrong format is selected, the picture may be distorted, black and white only, and in extreme cases may be unusable. PAL and NTSC PAL and NTSC are different international TV standards. Most video equipment supports one (or sometimes both) of these standards. Countries using NTSC include North America, most of South America, Japan and Taiwan. Note that the videophone is correctly setup at the factory for your region. If you are using an external TV or VCR which is PAL, you will notice that the built-in videophone display stretches, and some lines at the bottom are hidden. This is normal, and does not effect the external TV or VCR. Cam Type The format of the camera connected to the VIDEO IN. If the wrong format is selected, the picture may be distorted, black and white only, and in extreme cases may be unusable. Note that the videophone is correctly setup at the factory for your region. You should select either PAL or NTSC, rather than AUTO. 44

49 Miscellaneous menu When you select Miscellaneous, you are presented with another menu page. Use the Up and Down arrows to select an item, then press OK. Refer to page 24 for a visual display of each menu. Call Info menu This menu provides information about the call in progress. This is normally only used for diagnostic purposes. Information menu and Version menu Information, such as the software version and product serial number, which you will need if you require Technical Support. Audio Defaults, Video Defaults Restore the default audio/video settings. (These items have the same effect as the Restore Settings button but allow you restore Audio or Video settings independently.) Restart Phone Restarts the videophone. There are two rare circumstances when you may need to restart the videophone: If you changed the ISDN set-up during a call, so that the videophone was unable to restart automatically. (Refer to the Installation menu and the ISDN Profile menu earlier in this chapter for details.) If the videophone is left in an unusual state, possibly as a result of an ISDN fault. 6 Centre Text menu This menu enables you use the arrow keys to centre the on-screen text to suit your display. You may need to adjust this if you connect a TV set or other external display. 45

51 7 Troubleshooting This chapter contains information to help you if you have a problem with your videophone: Preliminary checks Message boxes Status Bar messages Re-setting the videophone Further assistance 7 47

52 Preliminary checks This section lists some common problems and the checks you should make before reporting a fault with your videophone. Power Indicator light not lit (No power) Check all connections. Check the mains outlet by plugging in another appliance. Indicator light red/amber May be in stand-by mode: lift the handset to see if it wakes up. Call connection No dial tone when handset lifted or Handsfree button pressed Check that the ISDN cable is properly connected at both ends. Test the ISDN line by connecting another ISDN telephone. Unable to make or receive any calls Check that you have the correct ISDN interface. Check that your ISDN related set-up (ISDN variant, Restricted/ Unrestricted mode and ISDN Profile) is correct, see page 40. Test the ISDN line by connecting another ISDN telephone. Unable to make outgoing calls; incoming calls OK Check that the SPIDs are correctly set, see page 41. Caller ID not shown for incoming call If true for all incoming calls, you may not have the Caller ID service enabled. Check with your ISDN provider. If true only for some incoming calls, the callers concerned are not supplying the information. 48

53 Unable to receive incoming calls; outgoing calls OK Check that the local Numbers or MSN are correctly set if appropriates, see page 41. Check that the screen is not showing the Speech Call, Video Call or Phonebook dialling screen. You will not be able to receive calls when you are in the process of making an outgoing call. If the videophone is sharing the ISDN line with another piece of equipment, such as a fax, the other equipment may be configured to answer incoming calls automatically as soon as they arrive, so that the videophone does not get a chance to answer. You can check this by temporarily disconnecting the other equipment, or by re-configuring it so that it rings a few times before answering, giving you time to answer the videophone first. The best solution to this problem is to use MSN (Multiple Subscriber Numbering) to give each piece of equipment its own number. Second B-channel fails to connect; 1B (half-rate video) calls OK Check Second SPID and local Number are correctly set, see page 41. Video calls to some equipment (usually older systems) fail to connect properly; other video calls work correctly The other equipment may not be properly H.320 compliant. Specifically it may not support H.263 video encoding. Try disabling H.263, see page 39. Unable to make video calls; speech calls OK Check that the Restricted/Unrestricted mode is correct, see page 39. Unable to make speech calls; video calls OK Check that the correct ISDN variant is selected, see page 39. Check with your ISDN provider that both data and voice services have been enabled. 7 49

54 Local audio / video No sound / pictures from videophone Has the volume / viewing angle setting been set too low. Have the Status Bar and the Self-view image been hidden, leaving a blank screen? (Press Self-View or Call Status to check.) Video black and white, squashed or distorted Check that you have selected the correct TV Type for your display in the audio-visual configuration, see page 44. (If there is a + sign on the Status Bar you have the Auxiliary audio-visual configuration selected, otherwise you are using the Main audio-visual configuration.) Video on built-in screen black and white, squashed or distorted when using VCR, TV or other external display If you wish to use the built-in screen at the same time as the external video equipment they must both must be the same type, see page 44. Call connected but no sound / pictures received from far end Has the far end audio / video been muted /frozen? Self-view window blank (blue); on-screen text and incoming video OK There is no camera connected to the video input you are using. This normally means that the videophone is set up to use an external camera but there is no camera connected to the VIDEO IN connector: You may have accidentally pressed the Aux button and switched to the Auxiliary audio-visual configuration which you have set up to use an external camera. Press Aux again to switch back. Look for a + sign on the Status Bar to check whether you are using the Main or Auxiliary audio-visual configuration, see page 22, and check the corresponding settings to ensure that the Video In setting is correct see page 44. If you do have a camera connected to VIDEO IN, check all connections, not forgetting the camera power. 50

55 Poor video quality Is it a half-rate or analogue video call (only one channel shown on the Status Bar)? You will get much better video quality from a standard-rate digital video call. Far end videophone may have limited frame rate or resolution. The lighting or general set-up at the far end may be poor, or the far end videophone may not be properly adjusted. Far-end audio / video Poor video quality seen at far end but local video quality OK Probably caused by poor lighting or positioning of your videophone. Call connected but far end is not receiving sound / pictures Is the local audio muted and/or video off? (Check for on-screen mute symbols.) Miscellaneous Some apparent problems can be cleared by re-powering the videophone. See Restarting the videophone later in this chapter. If you have accidentally adjusted the Audio and/or Video settings to unusable levels, you can restore them to their default levels by pressing Restore Settings (Shift Set Video). 7 51

56 Message boxes If the videophone detects a problem it will display a message on screen, for example: To remove the message once you have read it, press OK or Cancel. Most of these messages are straightforward, but the following may need a little more explanation: You are connected to two different videophones. Releasing second connection. There are two possible causes for this: You may have accidentally entered numbers which belong to two different videophones. If so, hang up the call, correct the numbers and dial again. You may have dialled correctly but there may actually be two videophones on the line you are calling (for example if you are calling a video server). Occasionally two different terminals will accept the calls on your first and second channels. If this happens, hang up and then re-dial. If the same thing keeps happening, inform the person you are trying to call: they may have a fault. 52

57 ISDN information codes Because ISDN is digital, an ISDN phone can provide more information about network events and status than a normal telephone. If you have persistent problems with your network, this information will help your ISDN provider track down and solve the problem. Alternatively, if your videophone is not set up correctly for your network, the ISDN information codes will help you correct it. The videophone displays the ISDN information codes in message boxes which contain: a brief explanation the number you dialled (so that you can check what you entered) the ISDN information code [in square brackets] For example: Note that these are not all error codes; many represent normal events, such as the number you called being busy, or the network being temporarily congested. The message should normally provide an adequate explanation, and the following table will help you correct any problems. If you persistently receive codes in the range even after carrying out the corrective action, contact your ISDN provider for help, quoting the ISDN information code. 7 53
