DC POWER CABLE CONNECTION

Locate the power input connector as close to the transceiver as
possible.

OBILE PERATION
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.
• We recommend you do not use the cigarette lighter
socket as 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, wrap heat-resistant tape
around the fuse holder to protect it from moisture and
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, then
attach the power cable to the battery terminals;
red connects to the positive (+) terminal and 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.
