Problem
The tone is very weak
and faint.
The volume control is
set to very loud
Possible causes
- The small tube piece is blocked by water deposits. Re-
move the small tube piece and shake or blow out the
water.
- Microphone is dirty.
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.
