DC POWER CABLE CONNECTION
■
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 the transmit output power may drop excessively.
1 Route the supplied DC power cable directly to the
vehicle's battery terminals using the shortest path
from the transceiver.
• When using a noise filter, install it with an insulator to
prevent it from touching metal on the vehicle.
• We recommend that you do not use the cigarette
lighter socket since some cigarette lighter sockets
introduce an unacceptable voltage drop.
• When routing the power cable through a hole in the
vehicle chassis or body, for example in the firewall at
the front of the passenger compartment, use a
rubber grommet to protect the cable from abrasion.
Dismantle the fuse holder to pass the cable through
the firewall.
• The entire length of the cable must be dressed to
isolate it 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,
then 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.

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.
