3 BATTERY CHARGING ■ External DC power operation An optional cigarette lighter cable (CP-12L or CP-19R; for 12 V cigarette lighter socket) or external DC power cable (OPC-254L) can be used for external power operation. (We recommend the CP-19R when you want to connect a 12 V cigarette lighter socket.) D Operating note • Power supply voltage must be between 10.0-16.0 V DC. (We recommend 11.0 V DC.) NEVER CONNECT OVER 16 V DC directly into the [DC IN] jack of the transceiver. • B E SURE to use a CP-12L, CP-19R or OPC-254L when connecting to a regulated 12 V DC power supply. Use an external DC-DC converter to connect the transceiver through a CP-12L, CP-19R or OPC-254L to a 24 V DC power source. • The voltage of the external power supply must be within 10-16 V DC when using either CP-12L, CP-19R or OPC254L, otherwise, use the battery pack/battery case. • Disconnect the power cable from the transceiver when not using it. Otherwise, the vehicle battery will become exhausted. • The power save function is automatically deactivated during external DC power operation. 15 Transceiver • CP-12L (Optional) to [DC IN] to cigarette lighter socket (12 V DC) • CP-19R (Optional) BP-264 • OPC-254L (Optional) to 11 V DC (power supply) Black: _ White: + NOTE: Up to 5 W (approx.) of maximum output power is available when using an external DC power.

BATTERY CHARGING
■
External DC power operation
An optional cigarette lighter cable (CP-12L or CP-19R; for
12 V cigarette lighter socket) or external DC power cable
(OPC-254L) can be used for external power operation. (We
recommend the CP-19R when you want to connect a 12 V
cigarette lighter socket.)
D
Operating note
• Power supply voltage must be between
10.0–16.0 V DC
.
(We recommend 11.0 V DC.)
NEVER
CONNECT OVER
16 V DC
directly into the [DC IN] jack of the transceiver.
•
BE SURE
to use a
CP-12L
,
CP-19R
or
OPC-254L
when
connecting to a regulated 12 V DC power supply.
Use an external DC-DC converter to connect the trans-
ceiver through a CP-12L, CP-19R or OPC-254L to a 24 V
DC power source.
• The voltage of the external power supply must be within
10–16 V DC when using either CP-12L, CP-19R or OPC-
254L, otherwise, use the battery pack/battery case.
• Disconnect the power cable from the transceiver when
not using it. Otherwise, the vehicle battery will become ex-
hausted.
• The power save function is automatically deactivated dur-
ing external DC power operation.
