360 Herndon Parkway Suite 1400 Herndon, VA 20170 http://www.rheintech.com FCC Certification Report Rev: 2 Page 46 2000500 Radio Shack Corporation TRC-520 19 MANUAL FEATURES You RadioShack TRC-520 40-Channel Mobile CB Radio provides two-way communications on the citizen’s radio band and also lets you tune to local and national weather service broadcests. This CB is perfect for recreational,busi- ness , or emergency use. You can call other people who have CBs at home,in Their venicles, or at campsites, (for ex- ample) You can also connect optional equipment to you CB such as external speakers , or a DC power supply and base station antenna to set up a base station in your home, The built-in 40- channel PLL (phase –locked loop) fre- quency synthesizer uses a precise fre- quency reference crystal for reliable and exact tuning. Your CB has these features: ACE(Audio Clarity Enhancer)– sup- presses noise levels while leaving the Signal intact during reception. It enhanc- es the transmission and provide a sig- nificant reduction in transmission and reception noise. WX/CB/Compass Switch – lets you quicklyselect among normal CB opera- tion,Weather mode,E.compass mode. NOAA 7 Channel WX band Receiver --lets you tune to seven national weather service frequencies which provide lo- cal weather conditions and forecasts. WX / Signal Indicator– showa the CB is ready to receive and indicates the reception of a weather alert Digital Weather Alert – uses Specif- ic Ares Message Encoding (SAME) Digital information to determine and display the level of weather events (does not limit alerts to a specific ar- ea). Convenient On-Microphone Chan- Nel Up/Down Controls–let you quick- ly scan the band for communications. Universal Mounting Bracket - lets You mount your CB securely in your ve- hicle. Specialized Squelch Circuit – com- pensates for fading signals and elimi- nates signal shopping during reception RFGain Control -prevent overload- Ing due to strong RF signals Maximum Allowable Legal Power Output –gives you the greatest avail- able range. TX Indicator- light to show when the radio is transmitting. Digital Channel Display-makes the channel number easy to see. 1 FEATURES Dual/MEM –lets you activeta Dual Watch Mode External Speaker Jack – Lets you connect your CB to an external speaker. Screw-On Mic Connector-ensures a seure microphone connection. To use this CB,you need a mobile or Base ststion antena Your local Ra- DioShack store has a wide variety of an- tennas. For more information,see “Connecting an Antenna”on page 6. The Federal Communications Commis- Sion(FCC)does not require you to have A license to operate this CB,However, You must know part 95 of FCC Rules.It Explains the proper operation of a Class D citizen’s band CB. We enclosed a Copy of part 98 with you CB radio. We recommend you record your CB’s Serial number here. The number is on The back of the CB. Serial Number: 2001 RadioShack corporation.
