3 Plug the charger into an AC wall outlet.

• Charging starts and the two TX-RX LEDs on the top panel light orange.

4 It takes approximately 8 hours to charge an empty PB-45L Li-ion battery pack.

After 8 hours, remove the charger plug from the transceiver DC-IN jack.

• When charging completes, the LEDs turn off.

5 Unplug the charger from the AC wall outlet.

Note:

X Never leave the battery pack in direct sunlight.
X The transceiver becomes warm while charging the battery pack.
X While the battery pack is charged, the ambient temperature must be within 0°C ~ 40°C (32°F ~

104°F). Otherwise, charging does not start. If the transceiver senses that the temperature is
more than 60°C (140° F) during charging, the transceiver stops charging.

X Before recharging the battery pack, use the battery pack until the transceiver stops receiving.
X Do not plug the charger into the DC IN jack for more than 24 hours.
X Unplug the charger as soon as possible after the charging period is over.
X After the battery pack is charged, do not unplug and plug the charger into the AC outlet again.

Unpluging the charger will reset the charging timer and the battery pack will be charged again.
This could result in over-charging.

X If the battery pack is recharged repeatedly before the battery pack is not fully used, the memory

effect (the battery pack will not allow the charger to recharge the battery to more than a certain
voltage level) may occur. In this case, turn the transceiver ON until it stops receiving in order
to discharge the battery pack, then recharge the battery pack as normal.

X When the battery is installed on the transceiver and you are using an optional rapid battery charger,

do not charge the battery from the DC-IN Jack. Charging the battery from the DC-IN Jack may
result in overcharging the battery which can result in the shortening of the battery life cycle.

X If the battery pack is not used for a long time, the battery pack capacity temporarily decreases.

In this case, charge the battery and use the battery pack until the transceiver stops receiving.
Repeat this procedure several times. The battery pack should recover its capacity.

X If the charger is plugged into the DC IN jack before the battery pack is attached, turn the

transceiver power ON and then OFF again to initiate charging.
