•
Volume Up Adjustment –
Each time you press and release the volume-up
S
button, a beep will
be heard in the earpiece as the volume increases one step. If you press and hold the volume-up button,
repeating beeps will be heard as the volume steps up to maximum. When maximum volume is
reached, “maximum” will be heard in the earpiece, and will be repeated until you release the volume-
up button.
•
Volume Down Adjustment –
Each time you press and release the volume-down
T
button, a
beep will be heard in the earpiece as the volume decreases one step. If you press and hold the volume-
down button, repeating beeps will be heard as the volume steps down to minimum. When minimum
volume is reached, rapidly repeating beeps will be heard.
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 Beltpac Batteries
When a Beltpac 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.
Change Base Station Batteries
When a base station battery becomes weak, repeating beeps will be heard in the Beltpac headset and the
POWER
light on the base station will be blinking red. When this happens, replace the batteries in the base
station with new or fully charged batteries as instructed on page 6.
