Battery Size
Battery sizes can be identified by a color code on
the packaging. Instruments like yours commonly
use either a size 10A battery (yellow marking on the
package), or size 312 battery (brown marking on
the package).
It is very important to use the correct size and type
battery for your hearing instrument.
Because of their size, it’s a
good idea to change and
replace batteries at a table
or desk to reduce the risk of
dropping the instrument
or battery.
BATTERIES

battery.
Your batteries have a _________ mark on
the package.

the battery, open the

likely to occur.
Changing Batteries
Remove the old battery by
pushing it out the top of the
fully opened door.
DO NOT pull it out the side
of the door.
Place the new battery in the
compartment with the plus (+) sign facing up.

Close the battery
compartment by swinging
the door until it snaps shut.
NEVER FORCE THE DOOR
SHUT. This could result
in serious damage. If the
door will not close easily,
check that the battery is placed properly in the
compartment and is not upside down.
Low Battery Indicator
Your hearing professional will check the box below
if the low battery indicator for your instruments is
turned on.
When the low battery indicator is turned on, your
hearing instruments will beep four times going from
a high-to-low pitch when the battery’s voltage is low.
Replace the battery when you hear these tones.
BATTERIES
The low battery indicator is turned on.

8
When the battery is too weak to power the hearing
instrument, you will hear a tone for two seconds and
the instrument will shut down. Replace the battery
when this happens.
Battery Caution
Because batteries can vary in size and performance,
your hearing professional is your best source for
lifespan estimates and verification that you are using
the proper size and type.
To help prevent the accidental ingestion of batteries,
keep them out of the reach of children and pets.
Always check your medication before ingesting –
batteries have been mistaken for pills.
