Batteries
The battery compartment located on the bottom of the amplifier also acts
as the on-off switch. When closed the unit is ON and when open the unit
is OFF. We recommend that you fully or completely open the battery door
when you go to bed at night in order to conserve battery power.

Low power: You will hear a series of melodic double beeps when the battery is low. You may
also hear increasing static. You will have approximately 30 minutes to change the battery (this
can vary, depending on the hearing settings and battery). We recommend that you always
have a new battery on hand.
Batteries
The proper battery size for your Otofonix Apex amplifier is a zinc-air #312. Before inserting the
battery into your amplifier, remove the brown tab and wait 1-2 minutes to allow the battery to
air activate. Your hearing amplifier has a low current drain and the battery should last approximately 7-10 days (16 hour days) . Loud noises and increased volumes levels drain the battery
more than quieter sounds.
