2After 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.
3To prevent the risk of short circuits, disconnect
other wiring from the negative (–) battery terminal
before connecting the transceiver.
4Confirm 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.
5Reconnect any wiring removed from the negative
terminal.
6Connect the DC power cable to the transceiver’s
power supply connector.
• Press the connectors firmly together until the locking
tab clicks.
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 transmit output power may drop excessively.
1Route 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 recommended not to use the cigarette lighter
socket since some cigarette lighter sockets introduce
an unacceptable voltage drop.
• If the power cable must be routed 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 so it
is isolated from heat, moisture, and the engine
secondary (high voltage) ignition system/ cables.
