The vehicle battery voltage must be between 11.5 ~ 14.5 Volts
DC. Be sure to use a battery that has sufficient current capacity.
If the current to the transceiver is insufficient, the display may
darken during transmission, or transmitting 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.
2.
If using the supplied power cable make sure the entire length of
the cable is dressed so it is isolated from heat, moisture, and the
engine high voltage ignition system.
3.
If using the optional Powerwerx TMCG-72 cigarette lighter plug
make sure your cigarette lighter socket in your vehicle can handle
12 VDC @ 12 Amps.
•
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 length of cable nessary to reach your battery. In
particular, never remove the fuse holders from the cable.
4.
Reconnect any wiring removed from the negative terminal.
5.
Connect the DC power cable to the transceiver's power supply
connector.
•
Press the connectors firmly together until the locking tab clicks.
