Thank you for purchasing the RadioShack TRC521 CB Radio. It provides two-way
communication on the citizen’s radio band and lets you tune to local and national weather
service broadcasts. It provides the maximum legal power output for the greatest available
range, and a built-in PLL (phase-locked loop) frequency synthesizer to reduce congestion.
CB radio provides hours of fun and entertainment! Listen and talk to people from all over the
country while traveling, and make new friends along routes that you regularly travel. It is also a
great way to keep informed of local emergencies, such as traffic accidents, road blocks,
weather alerts and so on.
