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 approxi-
mately 7-10 days (16 hour days) . Loud noises and increased volumes levels drain the battery
more than quieter sounds.
