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 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.

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, black connects to the negative
•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.

5Reconnect any wiring you may have removed from the negative battery terminal.
6Connect the DC power cable to the transceiver’s power supply connector.
•Press the connectors firmly together until the locking tab clicks.
