Microlink MLxS with Cochlear Freedom bte You will need: • A Microlink Freedom receiver • Three 675 batteries for Microlink Freedom Transmitting coil fits here Selector button screen Microlink Freedom receiver Increase/decrease buttons What to do: You need to consult the cochlear implant clinic before using the MicroLink Freedom. There is a default mixing ratio of 3:1 with the Freedom processor. However it is usually more practical to have a ratio of 1:1 so that when the transmitter is turned off there is no difference in the level of sound from the microphone on the processor. A program should be set up in this way at the clinic. This program should be selected when using FM. 1. Remove the battery rack by placing finger nails into the slots at the base of the controller unit and pulling downwards. 2. Put three 675 batteries into the MicroLink Freedom battery rack. 3. Plug the Microlink Freedom into the controller. 4. Press the selector button to turn on the speech processor. 5. Select the program for use with radio aids. 6. The processor will automatically detect the presence of the receiver. Sound can now be heard through the headpiece microphone and FM combined. The letters EA should show briefly on the screen when this happens. 7. To listen to microphone only press both the increase and decrease buttons together repeatedly until just an ‘M’ appears on the screen. 8. To re-engage FM, press both buttons repeatedly until ‘EA’ flashes on the screen and the ‘M’ remains there. Troubleshooting Have you definitely turned on the microphone? Particular care is needed with the Campus transmitter where there is a switch on the microphone itself. Listen through the Freedom monitoring headphones (Part number Z60832). Turn on the processor and plug the headphones into the socket on the base of the Microlink Freedom. Press both the increase and decrease buttons at the same time for a few seconds to activate the headphones. It is now possible to listen to signals from the microphone and FM system.
