6 Selecting Speaker Unit Length To get a good cosmetic and comfortable fit with Delta please consider the following; Selection of correct speaker unit length The speaker unit is available in four lengths and left/right versions. No. 1 is the shortest and no. 4 is the longest. The lengths most commonly used are size 2 and The goal is for the speaker to sit comfortably and hidden in the ear canal, for the wire to be flush with the skin, and for the top of the amplifier to sit horizontally on top of the ear, behind the pinna. Selection of correct dome size Insertion of speaker correctly when placing the instrument on the ear Using the ear grip, if necessary 10 11

7 Attaching the Speaker Unit Use the measuring tool to select the correct length of speaker unit. The correct length of speaker unit corresponds to the size-marking on the measurement tool that fits the top of the ear canal opening. Slide the speaker unit into the plug. Only slide in the direction of the plug. Do not force the speaker unit plug down. When the plug is in place, give it a firm push

8 Replacing the Speaker Unit Attaching the Ear Grip Gently pull off the speaker unit. Only pull in the direction of the plug. Do not pull upwards as this may damage the plug. The ear grip should be used to obtain a more secure hold in the ear canal. It is available in one version for both left and right ears. Insert the ear grip in the slot in the receiver. Important: Pull the ear grip until its top is positioned in the slot. During inserting, this top should point away from the dome as illustrated. If it is wrongly inserted, the ear grip might be difficult to place in the concha

9 Taking off the Ear Grip If the ear grip seems too long in the concha, you may cut/trim it to the desired length. Use caution not to leave a sharp and pointy end when cutting as this can cause irritation in the ear. Use a finger nail to dislodge the ear grip and push from the other side

10 Inserting and Placing the Device on the Ear Manipulating the Speaker Unit 1. Insert the speaker with a Dome/Micro Mould in the ear canal. 2. Place the amplifier behind the ear. The speaker unit with the Dome/Micro Mould should be placed far enough into the ear so that the speaker wire lies flush with the clients head. When looking at your client face-to-face, you should not If the speaker unit is too long, the amplifier will sit too low on the ear and the microphones will point vertically instead of horizontally. Also the wire will not follow the helix nicely round behind the ear. If the speaker unit is too short, the speaker will be difficult to place deep enough in the ear canal to get a secure hold and it may fall out. see the speaker wire protrude/stick out. 1 2 Speaker unit too long Speaker unit too short 18 19

11 If the wire is not flush with the skin, check that the insertion depth is correct. You may need to use another dome size if the speaker unit needs to move further in the ear canal. If the wire is still not flush, you might want to change the curve of the speaker unit to either straighten it a little or to change the insertion depth. This is not difficult, but the following steps are important to avoid damaging the speaker unit: Do not use excessive heat and do not exceed 130 C. S Curve To add length to the receiver, straighten out, or elongate the S portion of the speaker wire. Bend into the Canal Adjust this bend to stop the wire from bowing out from the side of the client s ear, or to increase the depth of speaker insertion. S-curve Bend into the canal Use a hair dryer or spectacle instrument at low heat setting Heat for a short time a matter of seconds Bend into desired shape and keep shape until wire is cooled off

12 Ear Pieces Selecting Dome Fitting Range for Domes Fitting Range for Micro Mould The Open Dome is available in three different sizes: 6 mm, 8 mm and 10 mm. The most commonly used The dome should sit comfortably in the ear canal and support and hold the speaker. Use an otoscope Open Dome 6 mm 8 mm 10 mm db HL Hz Micro Mould Custom Fit db HL Hz is the medium sized 8 mm dome. The Plus Dome is available in one size. The Open Dome is suitable for hearing losses up to 70 db in the high frequencies and is the best option for most users. The Plus Dome allows more midfrequency gain and extends the fitting range to 80 db HL in the high frequencies. It is suitable if the to inspect client s ear canal to determine dome size. user wants more loudness or more mid-frequency Plus Dome One Size gain. Genie will automatically prescribe Open or Plus Dome. The oval tip of the Plus Dome should always be placed on the speaker unit like illustrated: 22 23

13 Choosing the Correct Size of Domes Changing the Dome If the dome is too small, the speaker will not be securely positioned in the ear canal and it may also itch or tickle in the ear canal. If the dome is too big, it will be difficult to get deep enough into the ear canal or collapse in the ear canal and be uncomfortable to wear. Take off the old dome using your finger nails. Push the new dome onto the speaker. Give it a push to secure it safely Dome too small Dome too big 24 25

14 Micro Mould The Micro Mould is an acrylic custom solution that can be used instead of a dome. Micro Moulds are produced from a traditional, deep impression. The adaptor clearly indicates R/L colour marking. Up/Down Indicator Micro Moulds use tube-shaped vents, as in traditional ear moulds, but the length is shorter than standard vents. Therefore, the Micro Mould vent effect is much larger than its actual diameter. Genie prescribes the vent size, when Micro Mould is selected. Micro Moulds can also be used and selected in Genie for mild and moderate HF hearing losses, where open domes are prescribed. However, in these cases Micro Moulds are only recommended in case of problems with insertion or retention. Earpiece Actual vent size (mm) Effective vent size (mm) Open Dome 9 Plus Dome 3-4 Adaptor WaxStop Micro Mould Large Medium Small No Vent

15 Attaching the Micro Mould When fitting Delta with Micro Moulds follow the instructions below: 1. Find the correct speaker unit length and attach it to the amplifier (see Selecting Speaker Unit Length). 2. Carefully insert the receiver into the Micro Mould and click the Micro Mould on. Note: Make sure that the receiver is not angled when inserted into the Micro Mould. An odd angle will prevent the speaker from engaging the adaptor. The click sound indicates that the speaker is placed correctly, and should be made with only a little force. Don t force the two units together! 3. The Micro Mould can rotate axially to ensure maximum comfort. Before placing the Micro Mould in the ear, turn the Micro Mould until the up/down indicator points upwards

16 Taking off the Micro Mould The Micro Mould can t be detached from the receiver without the Micro Mould tool. When detaching the Micro Mould follow the instructions below: 1. Remove the WaxStop. 2. Place the Micro Mould in the tool as illustrated making sure that a. The cross in the adaptor is matching the tap of the tool. b. The Amplifier is positioned away from the tool or is being turned Press the arms of the tool carefully together. 4. Now the Micro Mould can be removed from the speaker unit. Note: If the Micro Mould has an extended shell part and is more than 9 mm long, use the end tap and carefully press to release the speaker unit. End tap 30 31
