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 .
Turning the hearing aid on and off
The battery compartment cover of your Flash hearing
aid also functions as the on/off switch . The hearing aid
is turned on when a battery is inserted correctly and
the battery compartment cover is completely closed .
The hearing aid is turned off
when the battery com-
partment cover is open .
Please remember to switch the hearing aid off when it
is not in use . Remove the battery if the hearing aid will
not be used for several days .
