What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications (listed below) do not transmit continuously. The BC350C scans programmed channels at the rate of up to 100 channels per second until it locates an active frequency. When scanning stops on an active frequency, it remains on that channel as long as the transmission continues. When the transmission ends, the scanner stays on the channel for 2 more seconds, waiting for another transmission. If no response is detected, the scanning cycle resumes until anoth-er transmission is received.
