Normal Mode Operation - Uniden UM355 Owner's Manual

How It Works
In addition to the two main operation modes, the UM355 also provides two different
"watch" modes which you can activate during any of the two basic modes. In the
watch modes, the radio briefly checks for activity on a specific channel, then returns
to its previous mode.
Watch mode What it does:
Triple Watch Checks for activity
on channels 16
and 67 every two
seconds.
Dual Watch Checks for activity
on Instant Channel
every two seconds.
NOTE: You are required to monitor channel 16 whenever your boat is underway.
You should have Triple Watch on at all times.
