Common Problems and Solutions
Hearing aid whistles or squeals
Check that the earpiece is inserted correctly. If this
is the case and the hearing aid still whistles or squeals,
please consult your hearing care professional.
No volume, level too soft or humming noise
Check if the volume level on your hearing aid is too
soft and adjust by increasing the volume level with
the optional remote control or SoundGate if available.
If you have no volume at all, check whether the hearing
aid is in mute position. If the problem still occurs,
check that the battery door is closed completely.
Also check if the battery is inserted correctly. Check
if the sound outlet (wax filter and dome) and
microphone inlet are clogged by dust or dirt. If the
problem still remains, change the battery. If the
problem still persists, contact your hearing care
professional.
Whirring noise, fading, weak or motor-boating sounds
Open and close the battery door several times or
clean the battery contacts carefully with a dry cotton
swab. If the problem still occurs, change the battery.
If the problem still remains, contact your hearing care
professional.
