FEATURES

Your Radio Shack TRC-488 40-Chan- nel 2-Way CB Radio is a high perfor- mance citizen’s band radio that also lets you tune to national weather ser- vice broadcasts. This CB is perfect for recreational, business, or emergency use. It lets you talk to other people with CBs at home, in their vehicles, or at camp sites. You can also connect op- tional equipment to your CB, such as a DC power supply and base station an- tenna to set up a base station in your home.

Your CB has the following features:

7-Channel WX Band Receiver — lets you tune to seven national weather fre- quencies so you can hear your local weather conditions as well as weather forecasts wherever you travel.

Emergency Channel Selector — lets you quickly switch to Channel 9 so you can report or monitor emergency situ- ations.

PLL (Phase-Locked Loop) Frequen- cy Synthesizer — provides reliable and exact tuning.

Hysteresis Squelch — automatically adjusts receiver sensitivity to compen- sate for fading signals and to eliminate signal chopping during reception.

Two Ceramic Filters — provide supe- rior channel selectivity and eliminate adjacent-channel interference.

Automatic Noise Limiting (ANL) — reduces noise caused by nearby elec- trical equipment such as motors or au- tomotive ignition systems.

LED Channel Display — displays the selected channel (1-40). When chan- nel 9 is selected with the emergency channel switch, the 9 flashes continu- ously. When a weather channel is se- lected, the display “blanks-out.”

RF Gain Control — lets you adjust the receiver gain to match the strength of the received signal.

Universal Mounting Bracket — lets you mount your CB securely in your vehicle or on a table or shelf in your home.

Important: To use this CB, you must connect a mobile or base station an- tenna (available at your local Radio Shack store). See “Installing an Anten- na” on Page 8.

For your records, we recommend you record your CB’s serial number in the space below. The serial number is lo- cated on the CB’s back panel.
