BATTERY LIFE
Before you operate the transceiver outside using a battery
pack, it is important to know how long the battery pack will
last.
If the battery saver setting is 1.0 sec and the GPS setting is
Off in the single band operation, the operating times listed in
the table below are the referential values under the following
cyclic conditions: TX: 6 seconds, RX: 6 seconds, Stand-by: 48
seconds
We recommend you carry extra battery packs with you, in
case the battery pack becomes depleted.

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.
When the PG-3J is connected to the cigarette lighter plug,
the transceiver automatically starts charging the battery pack.
While you operate the transceiver, it charges the battery pack
in the background.
Note:
¡
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:
¡
Do not use the PG-2W to connect directly to a vehicle battery
(12 V). Extensive voltage could result in damaging the
transceiver.
¡
If the input voltage exceeds approximately 17.5 V, the
transceiver automatically turns OFF.
CONNECTING TO A REGULATED POWER SUPPLY
To connect the transceiver to an appropriate regulated DC
power supply, use an optional PG-2W DC cable.
1
Confirm that the power of both the transceiver and the DC
power supply is OFF.
2
Connect the optional PG-2W DC cable to the DC power
supply; the red lead to the positive (+) terminal, and the
black lead to the negative (–) terminal.
Fuses (3 A)
3
Connect the barrel plug on the DC cable to the DC IN jack
of the transceiver.
•
While a DC power supply is connected with the DC IN
jack, the transceiver automatically initiates charging the
battery pack.
Caution:
¡
Install a lithium-ion battery pack or battery case when a DC
Power Supply is used. Failure to do so may result in burns.
Note:
¡
The supply voltage must be between 11 V and 15.9 V to
prevent damaging the transceiver. If the input voltage exceeds
approximately 17.5 V, the transceiver automatically turns OFF.
