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 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. If the problem still remains, change the
battery. If the problem still persists, contact your hearing
care professional.
