Microphone Gain Adjustment
Some users talk louder or softer than others. To allow for this, microphone gain adjustment is provided.
To increase microphone gain – Press the volume-up S button while holding down the ISO button in
the normal operating mode. The microphone gain increase can be monitored through sidetone, or preferably by
someone else on a Beltpac or at the base station.
To Decrease microphone gain – Press the volume-down T button while holding down the ISO button
in the normal operating mode. The microphone gain decrease can be monitored through sidetone, or preferably
by someone else on a Beltpac or at the base station.
NOTE: You will hear “Maximum” if you attempt to go higher than maximum microphone gain.
You will hear beeps if you attempt to go lower than minimum microphone gain.
Microphone gain will be saved in non-volatile memory and does not require readjustment each time
the power is turned on.
Batteries
Change Batteries
When a battery becomes weak, a voice in the
earpiece will say “Change battery.” When this
happens, take the Beltpac out of its pouch and
remove its battery. Slide the arrow-shaped battery-
release latch in the direction of the arrow. Pull up
on the end of the battery near the battery-release
latch and lift the battery out of the Beltpac, or turn
the Beltpac over and catch the battery in your hand.
When replacing a battery in the Beltpac, place the end
of the battery with the metal contacts into the battery
holder on the Beltpac, in the same position as the
battery you removed. Press the top of the battery
carefully into the battery holder until it snaps in place
under the battery-release latch.
