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.
D
Operating note
• Power supply voltage must be between
10.0–16.0 V DC
.
NEVER
CONNECT OVER 16 V DC
directly into the [DC IN]
jack of the transceiver.
•
BE SURE
to use
CP-12L
,
CP-19R
or
OPC-254L
when con-
necting a regulated 12 V DC power supply.
Use an external DC-DC converter to connect the trans-
ceiver through optional 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.
• Disconnect the power cables from the transceiver when
not using it. Otherwise, the vehicle battery will become ex-
hausted.
• The power save function is deactivated automatically dur-
ing external DC power operation.

NOTE:
Up to 5 W
(approx.)
of maximum output power is
available when using external DC power. However, when
the supplied voltage exceeds 14 V, the built-in protection
circuit activates to reduce the transmit output power to
2.5 W
