Cochlear Nucleus® Freedom Bodyworn

List of required parts

Nucleus Freedom speech processor

MLxi or MicroMLxS

Bodyworn controller

Bodyworn FM cable

Pre-Fitting

Enable auto sensitivity control (ASC) and use an audio 

mixing ratio of 1:1 for the dedicated FM program. Keep

the pre-processing e.g. ADRO strategy when used in the

default program.

When using MLxi, it should be programmed for the 

Cochlear Freedom Bodyworn (see page 32).

Fitting with the user

1. Turn all equipment Off.

2. If you haven’t already done so, remove the ear level

controller by twisting it from the processor.

3. Twist on the body worn FM cable. Plug the cable into the

proper receptacle on the body worn controller. Attach the

FM receiver to the ear level end of the FM cable. If you are

using MicroMLxS, move the switch to the double green dot

position.

4. Turn the body worn controller On by pressing and holding

the select button. Ensure that an “X” appears in the upper

right corner of the display. If not, press and hold the up

and down button at the same time until “EA” flashes and

an “X” appears in the display.

5. Test the patient’s speech recognition in quiet at normal

sensitivity with the CI alone and then through the wireless

FM system only (out of range of the processor microphone).

Performance should be similar between these two condi-

tions. If the FM is too loud or too soft, the FM programming

software from Phonak may be required to optimize the FM

volume level.

6. Evaluate FM benefit as well as the appropriateness of FM

settings through speech-recognition assessment in the

clinic and standardized questionnaires completed by the

recipient, family members and teachers.

Recommendations

To avoid interference, the following channels are recommended

to be used with the MicroLink Freedom

N Band: N09, N12, N13, N16, N17, N18, N52, N57, N61, N62,

N64, N65, N68, N73, N76

H Band: H06, H07, H16, H17, H18, H19, H20, H47, H48, H57,

H59, H77, H78, H79, H85, H86, H87, H88, H89, H90

Listening check

Attach the Cochlear monitoring headphones to the 

receptacle next to the FM receiver. Turn the system On by

pressing on the select button. Ensure that “X” is displayed

on the body worn controller. Now you can listen to both,

the processor microphone and the FM signal when

speaking into the FM transmitter. After about one minute

the headphones disable themselves. Note that the signal

quality of the monitoring phones or through the test

adaptor does not necessarily reflect the sound experienced

by the implant user.

Plug the MLxi or MicroMLxS into the headset checker (see 

page 12). Turn On the headset checker and FM transmitter.

Plug the MLxi or MicroMLxS into an audioshoe attached 

to a hearing instrument. Turn On the hearing instrument

and switch it to the FM program if required.
