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.
1Route 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.
2After the cable is in place, wind
then tie down the full run of cable. | 1 |
3To prevent the risk of short circuits, disconnect other wiring from the negative
4Confirm 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
•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.
