2What is Scanning?Unlike standard AM or FM radio stations, most two-way com-munications (listed below) do not transmit continuously. TheBC350C scans programmed channels at the rate of up to 100channels per second until it locates an active frequency.When scanning stops on an active frequency, it remains onthat channel as long as the transmission continues. When thetransmission ends, the scanner stays on the channel for 2more seconds, waiting for another transmission. If noresponse is detected, the scanning cycle resumes until anoth-er transmission is received.Types of CommunicationYou will be able to monitor communication such as:• Police and fire departments (including rescue and para-medics)• NOAA weather broadcasts (8 pre-programmed channels)• Citizens Band (CB)• Business/industrial radio• Motion picture and press relay• Utility• Land transportation frequencies, such as trucking firms,buses, taxis, tow trucks, and railroads• Marine and amateur (ham radio) bands• Air band• And many more in the 25-54 MHz, 108-174 MHz, and 406-512, and 806-956∗ MHz ranges∗ Excluding Cellular Telephone Band
