used for external power operation.
D D 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
of maximum output power is provided
(approx.)
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
.

• Disconnect the power cables from the transceiver when not
