And like we post the 3 sides of the radio. You can set up the quick functions on the side buttons in the software.

Monitor function. This function can also define on the side keys.

The scan is a carrier scan. That means if there is a signal on the current channel, you can receive it. And you can talk to others when the tones are the same, or you cannot hear the voice, but the indicator turns green. And if the signal disappears, your radio will keep scanning after 5 seconds.
