Before You Begin

Battery Pack Installation and Removal

・ 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. Insert the battery pack into the

battery compartment on the back of the radio while titling the Belt Clip outward, then close

the Battery Pack Latch until it locks in place with a “Click”.

・ To remove the battery, turn the radio off and remove protective cases. Open the Battery

Pack Latch on the bottom of the radio, and then slide the battery downward and out from

the radio while unfolding the Belt Clip.

Caution!: Do not attempt to open any of the rechargeable Ni-Cd packs, as they could

explode if accidentally short-circuited.

Low Battery Indication

・ As the battery discharges during use, the voltage gradually becomes lower. When the

battery voltage reaches 6.3 Volts, substitute a freshly charged battery and recharge the

depleted pack. The TX/BUSY indicator on the top of the radio will blink red when the

battery voltage is low.

・ Avoid recharging Ni-Cd batteries often with little use between charges, as this can

degrade the charge capacity. We recommend that you carry an extra, fully-charged pack

with you so the operational battery may be used until depletion (this “deep cycling”

technique promotes better long-term battery capacity)
