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 is too soft and adjust by
increasing the volume level with the control on your
hearing aid. If you have no volume at all, check whether
the hearing aid is in mute position. If the problem still oc-
curs, check that the battery door is closed completely.
Also check if the battery is inserted correctly. 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.
