INTRODUCTION

Your Radio Shack TRC-494 is a 40- channel emergency citizen’s band weatheradio that is specially de- signed for emergency situations. It comes with a handy carrying case so you can easily move it from one vehi- cle to another. And, the TRC-494 is also a 3-channel weatheradio, which you can use to receive weather infor- mation 24 hours a day.

You can power the TRC-494 from the cigarette-lighter socket in any vehicle that has a 12-volt, negative ground electrical system. You can also pow- er the CB from the supplied battery pack.

Its features include:

CB/Weatheradio Switch — lets you quickly switch from the CB to the weatheradio function.

Emergency Channel 9 Switch — immediately switches the CB to Channel 9, the universal emergency channel.

PLL (Phase-Locked Loop) Fre- quency Synthesizer — provides re- liable and exact tuning using a

frequency reference crystal.

Digital Channel-Number Display

makes it easy to see which chan- nel is selected.

Range Control — lets you eliminate background noise when no strong signals are present.

Built-In Ceramic Filters — provide superior selectivity and prevent adja- cent-channel interference.

Built-In Automatic Noise Limiter (ANL) — reduces noise caused by nearby electrical equipment, such as motors or automotive ignition sys- tems.

External Antenna Jack — lets you connect the TRC-494 to an external CB radio antenna.

Note: The TRC-494 comes with a telescoping antenna that you can at- tach directly to the CB. You can also attach it to the supplied magnet- mount base for use when your vehi- cle is not moving. If you plan to use the CB when your vehicle is moving, we recommend that you purchase a standard mount antenna.

Important: REACT is a nationwide 24-hour net- work that monitors Channel 9. Switch to Channel 9 in an emer- gency, and report the problem.

Note: REACT might not be available in all areas.
