Uniden MHS450 Radio Owner’s Manual
Some channels (for example, channels 13 and 67) limit
the power of transmission to 1 Watt so that there is less
interference between boaters attempting to use the channel
at the same time. If you switch to one of these channels, the
radio changes back to 1 Watt automatically. See the tables
starting on page 28 for a list of power-restricted channels.
Choosing Triple Watch or Dual Watch
In Triple Watch mode, the radio checks channels 16 and 9
every two seconds. In Dual Watch mode, the radio checks
channel 16 only. Generally, Triple Watch is used in areas
where channel 9 is used as a hailing frequency, while Dual
Watch is used in areas where channel 16 is used for distress
