Battery Pack Installation and Removal
r
To install the battery, hold the transceiver with
your left hand, so your palm is over the speaker
and your thumb is on the top of the belt clip. Care-
fully mate the battery four insertion slots with
their corresponding alignment tabs on the trans-
ceiver case, while tilting the Belt Clip outward.
Proper alignment occurs with the battery pack
offset about 1/2 inch from the top edge of the bat-
tery compartment.
r
Guide the pack to the tabs with a slight inward
pressure, then slide the battery pack upward, un-
til it locks in place with a “Click.”
r
To remove the battery, turn the radio off and re-
move any protective cases. Slide the Battery Pack
Latch
on the bottom of the radio toward the front
panel while sliding the battery down about 1/2
inch. Then lift the battery out from the radio while
unfolding the Belt Clip.
Do not attempt to open any of the re-
chargeable Lithium-Ion pack, as they
could explode if accidentally short-cir-
cuited.
Low Battery Indication
As the battery discharges during use, the voltage
gradually becomes lower. When the battery voltage
reaches 6.0 volts, it is time to substitute a freshly
charged battery and recharge the depleted pack. The
LED
indicator on the top of the radio will blink red
when the battery voltage is low (6 Volts or lower).
