Changing the battery
If you hear four rapid beep-tones while wearing your
hearing aid, it is an indication that the battery is nearly
exhausted. Once the battery is totally exhausted, the
hearing aid will be completely silent. Exactly how long
the hearing aid will function after the beep-tones var-
ies from one case to another. We recommend that you
always have a spare battery with you.
For adjustment of the beep-tone level or disabling of
the function, please consult your hearing care profes-
sional.
Never leave an exhausted battery in the hearing aid.
Exhausted batteries may leak, which could damage the
hearing aid. When changing batteries, it is a good idea
to hold the hearing aid over a table or a carpet, in case
you drop the hearing aid or battery.
