INITIAL INSTALLATION
DC POWER CABLE CONNECTION
The vehicle battery must have a nominal rating of 12V. Never connect the radio to a 24V
battery. Be sure to use a 12V vehicle battery that has sufficient current capacity. If the
current to the radio is insufficient the display may darken during transmission or transmitting
output power may drop dramatically.
1. Route the DC power cable supplied with the radio directly to the vehicle’s battery
terminals using the shortest path from the radio. We suggest you do not use the
cigarette lighter socket as some cigarette lighter sockets introduce an unacceptable
voltage drop. 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. 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.
