Dismantle fuse holder.
Passenger compartment
To prevent the risk of short circuits, disconnect other
wiring from the negative { —) battery terminal before
connecting the transceiver. Confirm the correct polarity
of the connections before attaching the power cable; 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. After completing
transceiver connections to the battery, then reconnect
any wiring removed from the negative terminal.
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. The entire
length of the cable must be dressed so it is isolated from
heat and moisture. 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.
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.
Only after completing the installation, connect the
transceiver’s power supply connector to the DC power
cable. Press the connectors firmly together until the
locking tab clicks.
