Normal mode with Triple and Dual Watch
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 nished and then
checks the channels.
