Getting your cochlear implant working with an FM

Published on

This is to help you get your cochlear implant working with an FM system.

Why? Because we have had difficulty getting Cochlear’s CP810 (Build D) Speech processor and two different FM receivers (Phonak’s MLXi and ML14i) to work together.

We found the MLXi and ML14i have different start up sequences with the CP810.

If we don’t follow these sequences exactly, our daughter who has bilateral (left and right) implants hears no sound from either the microphones or the FM receivers.

If you have constructive comments or more useful information please add that to the SlideShare page of this presentation.

Getting your cochlear implant working with an FM

  1. 1. Euro adaptor MLXi ML14i CP810
  2. 2. • Why? – Because we have had difficulty getting • Cochlear’s CP810 (Build D) Speech processor and • Two different FM receivers: Phonak’s MLXi and ML14i to work together We want to share what we have learned in collaboration with audiologists and technicians from • Australian Hearing • Sydney Cochlear Implant Centre and • Phonak to get these devices working together
  3. 3. • We found the MLXi and ML14i have different start up sequences with the CP810 • If we don’t follow these sequences exactly, our daughter who has bilateral (left and right) implants hears no sound – From either the microphones or the FM receivers
  4. 4. • There are four different components involved Euro adaptor MLXi FM receiver CP810 Speech Processor Inspiro FM transmitter
  5. 5. Start 1. Begin with – CP810 Speech Processor OFF – Euro adaptor connected to the CP810 – MLXi detached from the Euro adaptor – (The Inspiro transmitter can be on or off) 2. Turn the CP810 Speech Processor ON 3. Attach the MLXi to the Euro adaptor Finish
  6. 6. After that 3-step start up sequence • the wearer should hear sounds from the Speech Processor microphones and (whenever it is ON) from the FM transmitter • The FM transmitter can be switched on and off without having to go through the start up BUT – if the CP810 is switched off, you have to go through the 3-step start up sequence again
  7. 7. • There are three components involved Inspiro FM transmitter ML14i FM receiver CP810 Speech Processor
  8. 8. Start 1. Begin with – CP810 Speech Processor OFF – ML14i connected to the CP810 – The Inspiro transmitter must be OFF 2. Turn the CP810 Speech Processor ON – Note: at this point, the wearer will hear no sound 3. Turn the Inspiro transmitter ON Finish
  9. 9. • The Inspiro FM Transmitter’s microphone lead is also its aerial – It must be uncoiled to send the strongest signal • FM attachments make the system more vulnerable to moisture and corrosion – We’ve started taking the FM receivers off when using Cochlear’s Aqua Accessory just in case
