Uniden MHS450 Radio Owner’s Manual
Both Weather Alert and Triple/Dual Watch in scan mode
You can activate Weather Alert Watch and Triple/Dual Watch
at the same time. The radio performs both checks at their
scheduled time:
Weather mode
The NOAA weather channels now cooperate with the FCC to
alert you of other hazards besides weather (child abduction
alerts, nuclear, biological, etc.). In weather mode, the radio
monitors one of the ten NOAA weather channels. If any type
of alert is received for your area, the radio sounds an alert
tone and displays the type of alert.
Using the radio in weather mode
You cannot transmit while in weather mode.
To enter weather mode, press the
WX-ALERT
button.
Weather mode can filter out alerts that do not affect
your location if the location code (FIPS code) of the
alert is entered in your radio (see page 22). If you have
no FIPS codes programmed into your radio, the radio
will notify you of all alerts in any area.
To turn off the radio’s alert tone, press any button.
To cancel weather mode and return to the previous
marine channel, press the
WX-ALERT
button again.
