1 PREPARATION
CHARGING THE Li-ion BATTERY PACK
The Li-ion battery pack can be charged after it has
been installed onto the transceiver. The battery pack
is provided uncharged for safety purposes.
1 Confirm that the transceiver power is OFF.
While charging the battery pack, leave the
transceiver power OFF.
2 Insert the charger plug into the DC IN jack of the
transceiver.
3 Plug the charger into an AC wall outlet.
Charging starts and 2 LEDs on the top panel
lights orange.
4 It takes approximately 3.5 hours to charge an
empty PB-42L Li-ion battery. When charging
completes, the LEDs unlight; remove the charger
plug from the transceiver DC IN jack.
5 Unplug the charger from the AC wall outlet.
Note:
If you turn the transceiver ON and press [F], [LOW/ BATT] while
charging the battery pack, “CHARGING” appears. “STANDBY”
appears when the charging completes.
The transceiver becomes warm while charging the battery pack.
If the charger plug is plugged into the DC IN jack before the
battery pack is attached, turn the transceiver ON and then OFF
again to initiate the charging.
Exceeding the specified charge period shortens the useful
life of the Li-ion battery pack.
The provided charger is designed to charge only the
provided PB-42L Li-ion battery pack. Charging other models
of battery packs may damage the charger and battery pack.
Do not press [PTT] while charging.
The battery pack must be kept in cool and dry place.
Never leave the battery pack in the direct sun light.
CONNECTING TO A CIGARETTE LIGHTER
SOCKET
To connect the transceiver to the cigarette lighter
socket in your vehicle, use an optional PG-3J
Cigarette Lighter cable.
While the PG-3J is connected to the cigarette lighter
plug, the transceiver automatically start charging the
Li-ion battery pack (PB-42L). When you operate the
transceiver, it charges the Li-ion battery pack in back
ground. If the transceiver is turned OFF, the 2 LEDs
light orange while charging. When the charging
completes, they turn OFF {above}.
To connect with an external 24 V power source via a DC-DC
converter, only use the optional PG-3J Cigarette Lighter cable.
Using the PG-2W DC cable in this situation may cause a fire.

Note: If the input voltage exceeds approximately 16.5 V, warning

CONNECTING TO A REGULATED POWER
SUPPLY
To connect the transceiver to an appropriate
regulated power supply, use an optional PG-2W
DC cable.
1 Confirm that the power of both the transceiver and
the power supply are OFF.
2 Connect the optional PG-2W DC cable to the
power supply; the red lead to the positive (+)
terminal, and the black lead to the negative (–)
terminal.
3 Connect the barrel plug on the DC cable to
the DC IN jack of the transceiver.
If the transceiver is turned OFF while a regulated
power supply is connected with the DC IN jack, it
automatically initiates charging the Li-ion battery pack
(PB-42L) {above}.
Note:
If the DC power supply voltage is below 12.0 V DC, you may not
be able to charge the Li-ion battery pack (PB-42L).
The supply voltage must be between 12.0 V and 16.0 V to
prevent damaging the transceiver. If input voltage exceeds
approximately 16.5 V, warning beeps sound and “VOLTAGE
ERROR” appears. Remove the DC IN jack plug immediately.
If the DC power supply voltage is above 14.5 V DC and “H” (High
Power) is selected, “H” icon blinks and the output power is
reduced to “L” level (Low Power) automatically {page 41}.
