Problem
Volume
control is set
very high
Possible cause
The hearing amplifier's
earplug is not
positioned correctly in
the ear, meaning the
hearing amplifier may
not function correctly or
an unpleasant whistling
sound (acoustic
feedback) may be
heard.
Solution
- Switch off the hearing
amplifier and insert it
into your ear. Make
sure that the hearing
amplifier is inserted
correctly.
- If the earplug does
not fit correctly in your
ear, try a different
size. If possible, use
an earplug that fits
correctly. If you have
any doubts, please
contact Customer
Services.
