What is Roger? Roger is a digital wireless radio system allowing for long range, low delay, and full audio broadcast to miniature low power receivers. It operates in the 2.4GHz band, utilizing adaptive frequency hopping to avoid electromagnetic interference, and has an audio bandwidth around 7,300Hz. The frequency hopping occurs 800 times per second. It is adaptive both the microphones and the receivers are constantly checking for and avoiding any potential interferences There are no channels to manage It is like each and every Roger microphone has a unique address
How is Roger different from FM? Dynamic FM uses a specific channel at 216 MHz It stays on that channel at all times, even if there is another device on the same channel. Roger transmits on the ISM (Industry, Science, and Medical) band. This is centred at 2.4 GHz. However, unlike FM, frequency planning is not required with Roger because Roger does not use set frequencies but employs frequency hopping technology providing zero hassle, avoiding interference and providing a secure (tap proof) signal. FM
Is Roger better than FM? Why? Roger provides better performance in high noise than does Dynamic FM due to advanced digital processing. It reduces the amount of noise picked up by both the transmitting microphone and by the hearing instrument microphone. This results in a much higher word understanding capability. See next slide for Dr. Linda Thibodeau and Dr. Jace Wolfe s data with hearing aids and cochlear implants. It is interference free due to the unique frequency hopping technology. It is zero hassle since managing frequencies is unnecessary and it is simple to connect. FM

Roger receivers at a glance Design-integrated receivers Discrete click-on receivers for Phonak hearing instruments Water-resistant or tamperproof when paired with select hearing instruments Indicated by a number (Roger 18, Roger 15, etc.) Miniature universal receiver The smallest universal receiver that fits every BTE hearing instrument & DAI cochlear implant Fits into ComPilot/ComPilot II Universal inductive neckloop receiver Simple-to-use Roger receiver that hangs around the neck Compatible with any hearing device with a T-Coil
Summary: Design Integrated Solutions Receivers designed for a specific Phonak hearing aid Small, robust and discreet Water resistant Easier for patients: fitter adds receiver rather than patient attaching and removing Get maximum benefit from Roger highest SNR Ideal Candidates: All BTE users, active clients who need water resistance
Summary: Universal Ear Level MLxi Receivers designed for any BTE with DAI (maximum flexibility) Works with virtually every BTE (Phonak + other manufacturers). Small and robust Not water resistant Still get maximum benefit from Roger highest SNR Ideal Candidates: Schools, clients who need flexibility
Summary: RogerX + Compilot/Compilot II Maximum flexibility Small and robust Not water resistant But! You will NOT get maximum benefit from Roger. The dynamic gain changes in the Roger receiver do not translate in hearing aid when coupled to a streamer. Ideal Candidates: Clients who use ComPilot frequently will find adding Roger receiver easy Hearing instruments without telecoil or DAI (eg. Audéo S series, Audeo Q312)
Summary: Roger MyLink Universal Neck Loop receiver Easy to use But! You will NOT get maximum benefit from Roger. Higher SNR than with Bluetooth microphone Ideal Candidates: CI users with telecoils Hearing instruments that do not have DAI

Some Myths about Roger Too Expensive: Contact us about becoming Roger Approved Partner to receive preferred pricing and support Too Complicated The EasyPen is extremely easy to use Much easier to use than a Bluetooth microphone and streamer Patients won t use them The number one reason that patients report not using FM is not the cost, complexity or cosmetics. Instead the main reason patients report is that no one ever told them about this technology. Other people won t use the microphone Peter says malarkey, nonsense, rubbish. He uses it all the time with strangers. Never had a problem. Few patients need them Need to do the LiSN-S PGA with all patients. 100% of patients with severe losses need Roger. And a surprising number of patients with moderate losses also need higher SNR s.

How Effective is Automatic Mode? Extremely! Correct microphone settings (gain, beam former, noise cancellation) are automatically applied depending on three factors: Orientation towards the direction of gravity of the Roger Pen (accelerometer) Environmental noise Volume of voice of interest Based on feedback from users and from Peter s personal experience, we have found that people rarely use the manual microphone mode settings as the automatic mode is extremely accurate at selecting the correct microphone. This is why the decision was made to remove the manual microphone button from the EasyPen.
Roger Clip-On Mic in detail Two Buttons only On/Off/Mute Connect Directional Microphone only. Sounds similar to interview mode of Pen and EasyPen. No Voice Activity Detector Designed to be worn by communication partner Audio input Multiple microphone network
Ideal Candidates for Roger Pen Tech Savvy patients. Good visual acuity Good manual dexterity Needs Roger as indicated by LiSN-S PGA hearing in noise test. Lifestyle analysis indicates need to hear better in a variety of listening environments Requires Bluetooth for mobile phone use
Ideal Candidates for Roger EasyPen EasyPen can be used by all ages Since buttons are larger they are easier to see and feel. Patient already successfully using icom/compilot/compilot II/ ComPilot Air as a Bluetooth solution. Or patient has no need for Bluetooth Appropriate for Geriatrics Teens in School Adults of all ages Suggestion: For patients with decreased visual acuity select the Petrol or Ruby coloured Pen. Better contrast with the two buttons
Ideal candidates for Roger Clip Mic Suitable for all ages Reasonable manual dexterity and visual acuity. Even thought here are only two buttons, these buttons are smaller than the EasyPen Clip Mic only comes in silver Does not require Bluetooth for mobile phone use. Excellent additional microphone for using in a MultiTalker Network Peter prefers the EasyPen over the Clip Mic if this is the only microphone a patient uses.
Are there any new assessment tools to assist in determining candidacy for remote microphone technology? We strongly recommend adding a speech-in-noise test to determine the client s ability to deal with noisy environments. Our recommended speech-in-noise test is the LiSN-S PGA Test from NAL. Phonak is the official distributor of the LiSN-S PGA Test. LiSN-S PGA has some unique features which will help fitters to justify their recommendations and inform clients of their hearing status and the required intervention to improve speech understanding in noise. LiSN-S PGA gives clear, individual, technology recommendations how to improve speech understanding in noise. The client gets an evidence based recommendation
LiSN-S PGA Diagnostic & Counseling tool Green: Patient will have mild problems understanding speech in noise Yellow: Even with amplification, patient requires a higher SNR than most people to understand speech in noise. Advanced directional microphone technology is recommended Red: Even with hearing aids and advanced directional microphone technology, patient will struggle to hear speech in the presence of background noise. An FM system is recommended.
