Battery Pack Installation and Removal

rTo 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.

rGuide 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.”

Tilt the Belt Clip

Insert the Battery Pack

rTo 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).

CAUTION

Danger of explosion if battery is incorrectly

replaced.

Replace only with the same or equivalent type.
