FM: a must for every cochlear implant Phonak’s FM systems improve the signal–to-noise ratio and thus the user’s ability to understand speech in noise. Three major factors that influence the signal-to-noise ratio and the quality of the speech signal are: background noise, reverberation, and distance. By delivering the signal of interest via FM (radio waves), the strength and quality of the sound remains constant across the distance from the speaker to the hearing impaired individual.
Dynamic FM Dynamic FM is Phonak’s latest and most advanced FM platform. It has completely reshaped the face of FM technology. Dynamic FM systems are not merely pieces of hardware transmitting sound from one place to another. They are masterpieces of wireless technology, capable of adapting themselves continuously to the actual surroundings. The most important feature of Dynamic FM is its adaptive FM advantage. It adjusts the gain of the FM receiver, depending on the ambient noise.
Dynamic FM Transmitters inspiro is the Dynamic FM transmitter that is ideally suited to the needs of both regular and special school teachers. inspiro’s award-winning design, comfortable form factor and easy-to-read color display make using this transmitter a cinch, plus it features programmable soft keys, an alarm clock, a wide range of housing options and many more features designed to help teachers enjoy the performance benefits of Dynamic FM without technical know-how.

Fitting guidelines Introduction Successful application of an FM system with cochlear implants depends on several clinical-adjustable parameters. In the receiver, the FM gain may influence speech recognition. Within the speech processor, the input dynamic range (IDR), microphone sensitivity and audio mixing ratio may affect performance. Recent studies have evaluated the best settings for optimal FM performance. With Dynamic FM, the need for adjusting processor parameters in noise should be negligible.
Achieving FM only In some cases, adults prefer an FM only setting to focus on the primary signal delivered over the FM channel. The table below shows how to achieve FM only. Cochlear Corp Select the highest possible mixing ratio or reduce the microphone sensitivity to 1. BP100: Select the optional DAI program Cochlear Baha® Divino, Intenso, Compact: move switch of MicroMLxS to one dot. Advanced Bionics Select AUX only audio mixing setting MED-EL MED-EL processors are DPAI no hearing instruments.
Cochlear Nucleus® Freedom BTE 8. When FM is not in use, press both sides of the increase/ decrease button to toggle back to M only. This will resume normal processor microphone function.

Turn On the hearing instrument and switch it to the FM program if required.
FAQ How do I perform a system check? Some manufactures offer monitoring headphones, which can be connected to the processors. The headphones usually allow listening to the processor microphones and FM signal in parallel. Phonak offers a headset checker which has a euro plug. Here you can plug in all universal FM receivers or another receiver over the dedicated adaptor. The universal FM receivers can also be plugged into an audioshoe connected to a hearing instrument.
Programming a receiver with FM SuccessWare MicroMLxS, MyLink+, MyLink and MicroLink Freedom are pre-programmed and ready to be used. However even when the fitting instructions in this brochure are followed closely it might be necessary to change the default channel, adjust the FM Advantage (FM gain) and/or the Confirmation Beep level. For MLxi it is recommended to program this with FM SuccessWare prior to use with a CI speech processor, in order to achieve optimum interface matching characteristics.
Programming options Programming interfaces Programming MLxi Via the FM programming interface 1. Click Express Fitting. 2. Select MLxi and click “Next”. 3. Choose “Detect receiver channel” or manually select the desired channels and define the default channel, then click “Next”. 4.
