DC POWER CABLE INSTALLATION
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 you are using a noise filter, it should be installed with
an insulator to prevent it from touching any metal on the
vehicle.
• We recommend you do 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.
2 After the cable is in place, wind 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, black connects
to the negative (–) terminal.
• Use the full length of the cable without cutting off any
excess, even if the cable is longer than required. In
particular, never remove the fuse holders from the cable.
5 Reconnect any wiring you may have removed from
the negative battery terminal.
6 Connect the DC power cable to the transceiver’s
power supply connector.
• Press the connectors firmly together until the locking tab
clicks.
