Scan mode keeps hopping through your saved channels and stops when it hears someone talking.
Imagine a security guard watching ten screens at once. Scan mode is like that, but for channels. Your radio jumps from channel to channel — usually a few channels per second — and the moment it detects any transmission on one of them, it stops and lets you listen. When the transmission ends, it starts hopping again.
What is scan mode useful for, really? Mostly for listening. If you’re monitoring a team spread across different channels, or you just want to hear what’s happening on the air, scan on walkie talkie mode beats manually clicking through every channel. Here’s the catch though: if you have a lot of channels programmed in, the radio can take a couple of seconds to loop back around. Someone could talk and you’d miss the start of it. It’s a tradeoff.
Most radios scan whatever channels are in your scan list. Some let you add or remove channels from that list, some just scan everything you’ve got. And if your radio has a priority channel feature, that’s the one it keeps checking even while it listens to others. Not every model has that, so check your manual.
