Uniden UM425 VHF DSC 사용자 설명서

Every 2 seconds, the radio 

checks channels 9 & 16.

Press and hold the 

 button (on the radio or the microphone) for two 

seconds to turn Triple/Dual Watch on or off. (To change between Triple or 

Dual Watch, see page 21.)

If you activate Triple Watch while operating in normal mode, the radio checks 

channels 16 and 9 every two seconds; with Dual Watch turned on, the radio 

only checks channel 16. The radio will not check channels 16 or 9 while you 

are actively transmitting; it waits until your transmission is finished and then 

checks the channels.
