Operating note
• Power supply range is 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-19R
or
OPC-254L
when connecting a
regulated 12 V DC power supply.
Use an external DC-DC converter to connect the transceiver
through optional 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-19R or OPC-254L, oth-
erwise, use the battery pack.
• Up to 5 W
(approx.)
of maximum output power is provided
with the external DC power operation, however, when the
supplied voltage exceeds 14 V, the built-in protection circuit
activates to reduce the transmit output power to 0.5 W
(ap-
prox.)
.
• 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 during
external DC power operation.
