Low battery indication
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 low battery indi-
cation varies from one case to another. We recommend
that you always have a spare battery with you.
If you wish to have the beep-tone function disabled,
please consult your hearing care professional.
Never leave an exhausted battery in the hearing aid.
Exhausted batteries may leak, damaging the hearing
aid. When changing battery, it is a good idea to hold
the hearing aid over a table.
