DVANCED FUNCTIONS
10.1 Channel scanning
This function is particularly helpful when multiple channels have been programmed. It allows you to follow radio
traffic, as well as to respond to calls from different channels. When the radio picks up a valid signal during
scanning, it pauses on that channel and communication is heard on the speaker. When the signal ends, scanning
begins again automatically.
If CTCSS/DCS or selective calls have been previously programmed, the device can be programmed to pause only
at incoming signals containing the appropriate signals.

you release the PTT, the scanning will begin again automatically.
