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.

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

How to set aicom t70a to repeater
To set the Icom IC-T70A to repeater mode:
1. Set the receive frequency (repeater output frequency).
2. Set the shift direction of the transmit frequency (-DUP or +DUP).
3. Push [PTT] briefly, then push and hold [PTT] again for 1 to 2 seconds to transmit a 1750 Hz tone burst signal (if required).
4. If "OFF" appears, check the frequency offset or shift direction.
