•Installation and Operation instructions are for satisfying FCC RF Exposure compliance.

•To receive very weak signals, turn SQUELCH counterclockwise. You hear noise between transmissions, but you also hear weak transmissions (those not strong enough to break through a higher squelch setting).

•If you experience interference from nearby frequencies, turn RF GAIN counterclockwise to reduce the receiver’s sensitivity.

Although this transceiver is designed mainly for mobile use, you can also use it as a base station with an AC power source.

For base station installation, you need these items:

•13.8-volt DC power supply that can supply at least 2 amps .#

•base station antenna.

•coaxial antenna cable and connectors, available at your RadioShack store.

For the best performance, place the antenna as far as the cable length..#

Follow these steps to install the CB as a base station.

1.Mount the base station antenna as described in its owner’s manual. Rý.#

2.Connect the antenna to ANTENNA on the back of the CB.

3.Connect the transceiver’s black power wire to the negative (–) terminal on the DC power supply.

4.Connect the transceiver’s red wire (with the in-line fuse) to the positive (+) terminal on the DC power supply.

5.Connect the DC power supply to a standard AC outlet.
