Problem
The volume control is
set to very loud
Possible causes
The earpiece of the hearing amplifier does not fit correct-
ly in the ear, meaning that the hearing amplifier may not
function correctly in certain circumstances or an unpleas-
ant whistling sound (acoustic feedback) can be heard.
This can be prevented in the following ways:
- Switch off the hearing amplifier and insert it into the ear.
Ensure that it is inserted correctly.
- If the earpiece does not fit correctly in the ear, try it
again with another attachment. It is recommended
to use an earpiece that fits correctly. If you have any
doubts, please contact Customer Services.
