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 .
