External Dc Power Operation; Operating Note - Icom IC-92AD Instruction Manual

■ External DC power operation

An optional cigarette lighter cable
or external DC power cable
cigarette lighter socket)
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.

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 .
