DC POWER CABLE CONNECTION
LOCATE THE POWER INPUT CONNECTOR AS CLOSE TO THE
TRANSCEIVER AS POSSIBLE.
■
Mobile Operation
The vehicle battery must have a nominal rating of 12 V.
Never connect the transceiver to a 24 V battery. Be
sure to use a 12 V vehicle battery that has sufficient
current capacity. If the current to the transceiver is
insufficient, the display may darken during transmission,
or transmit output power may drop excessively.
1 Route the DC power cable supplied with the
transceiver directly to the vehicle's battery
terminals using the shortest path from the
transceiver.
• If using a noise filter, it should be installed with an
insulator to prevent it from touching metal on the
vehicle.
• It is not recommended to use the cigarette lighter
socket since some cigarette lighter sockets introduce
an unacceptable voltage drop.
• The entire length of the cable must be dressed so it
is isolated from heat, moisture, and the engine
secondary (high voltage) ignition system/ cables.
2 After the cable is in place, wind heat-resistant tape
around the fuse holder to protect it from moisture.
Tie down the full run of cable.
3 To prevent the risk of short circuits, disconnect
other wiring from the negative (–) battery terminal
before connecting the transceiver.
4 Confirm the correct polarity of the connections,
and attach the power cable to the battery
terminals; red connects to the positive (+)
terminal, black connects to the negative (–)
terminal.
• Use the full length of the cable without cutting off
excess even if the cable is longer than required. In
particular, never remove the fuse holders from the
cable.

5 Reconnect any wiring removed from the negative
terminal.
6 Connect the DC power cable to the transceiver's
power supply connector.
• Press the connectors firmly together until the locking
tab clicks.
Press
