Thank you for purchasing the RadioShack 40-Channel Mobile CB with Weather Alert. It 
provides for communication on the citizen’s radio band, lets you tune to local and national 
weather service broadcasts, and lets you connect an optional PA speaker to use the public 
address function. You can monitor the sound of CB or weather alert over a PA system while in 
PA monitor mode. It has the maximum legal power output for the greatest available range, and 
a built-in PLL (phase-locked loop) frequency synthesizer provides consistent, exact tuning.

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.
