for 6 seconds, and in some models a light-emitting diode lights up.1
2. While this is happening, remove the hearing aid from the Widex USB
Link and listen to it.
3. In Compass, select whether the hearing aid is for the left or right ear.
4. Repeat the procedure if you are fitting two hearing aids.
5. Click Next to connect the hearing aids.

tion is correct.
7. Position the hearing aids in the client’s ears. Place the Widex USB Link
around the neck of the client.
