1.Connect the BLACK wire of the power cable to the NEGATIVE (-) side of your power source.

2. Connect the RED wire of the power cable to the POSITIVE (+) side of your power source.

3. NOTE: To extend the life of the radio, use waterproof tape to seal electrical connections.

4. Install your antenna according to the manufacturer’s instructions.

details. (In summary, the FCC recommends

that antennas up to 3 dB be installed a minimum of 3 feet from any occupied location; antennas over 3 dB should be installed at least 6 feet away.)
