by scanning, you can monitor channels and codes for transmissions and lock in on the one that interests you. more importantly, you can find someone in your group who has accidentally changed channels and is talking during your scan.

   

    code is set to 0, then the radio will check for activity on each channel regardless of the code in use on that channel. if you activate scan while the code is set on 1 to 38, the radio will check for activity on each channel, but only for codes 1 to 38.

    transmissions using code 0 are ignored. when the radio detects channel activity, it stops on that channel and displays the code in use.

   

    activity is detected on a channel, the radio will stop scanning and you will hear whatever transmissions are detected. the radio's display will show the channel and code on which activity was detected.
