Uniden UM425 VHF DSC 사용자 설명서

You can save channels into memory and then use scan mode to monitor 

those channels. When the radio detects a signal on a channel, it pauses on 

that channel as long as the signal is received; when the transmission stops, 

the radio will continue scanning.

The radio scans about 

5 channels in 1 second.

When it detects a signal, the radio stays on the 
channel until you press the 

 button or the 

signal stops.
