Fitting

1. Turn speech processor, FM receiver and transmitter off.

2. Plug the orange cable into the MicroLink CI S.

3. Plug the MicroMLxS into the MicroLink CI S. Leave the receiv-

er in the double green dot position.

4. Attach the MicroLink CI S to the external input socket on the

speech processor.

5. Turn on the speech processor, FM transmitter and MicroLink

CI S in that order to avoid transient sounds.

6. Select a program that allows for sensitivity adjustment.

7. Determine speech perception in quiet with the CI alone at

normal (12) sensitivity. Repeat test with the FM system. If

scores are poorer with the FM system, increase the gain of the

MicroLink CI S until comparable performance is achieved.

8. Determine speech perception with the FM system in noise.

Decrease mic sensitivity in two-unit increments until signifi-

cant FM benefit is demonstrated.

Troubleshooting

Listening check #1

The environmental and FM signal can be heard simultaneously

through the monitoring phones to confirm function of the head-

piece mic and the FM system.

Listening check #2

1. Plug the receiver and adapter into a test amplifier, e.g. Radio

Shack speaker, with the orange patch cable.

2. Insert a battery into the MicroLink CI S and turn it on.

3. Put the MicroMLxS receiver in the double green dot position.

4. Turn on the FM transmitter. While speaking into the transmit-

ter, listen for the clear signal with minimal background noise.

This check will not reflect the sound quality that the patient

will hear but will confirm function and transmission of the

FM system.

5. To check the FM system, remove the MicroMLxS and plug it

into a working hearing aid and audioshoe or a Phonak

MicroLink Headset checker. Turn on the transmitter and listen

for a clear signal.

Listening check #3

1. Follow your audiologist’s recommendations for conducting a

listening check of your speech processor.

NOTE: You may choose to disable the volume control. If both

the microphone sensitivity and the volume controls are

available, press the Select button to alternate between

them.
