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.

##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.

13.8V DC

5.If necessary, consult the FCC guidelines for

antenna separation. See Antenna Selection

and Installation on page 51 for more 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.)

6.Connect the PL-259 connector from the antenna lead-in wires to the SO238 connector labeled ANTENNA on the back of your radio.
