Weather Radio Mode
Weather radio mode allows you to receive weather broadcasts from your
local weather service anytime of the day.
To use weather radio mode, simply press the WX button on the keypad.
The scanner will quickly scan and lock on to the first active weather
radio frequency it receives. You can use the 5 or 6 keys on the 5-way
pushbutton pad to force the radio to look for other weather radio
transmitters. It is generally best to select the weather radio transmitter that
provides you with the strongest signal. You can use the signal meter to help
you chose the best weather radio transmitter for your area. While operating
in Weather Radio Mode, your scanner will alert on SAME messages that
match the SAME location codes you have entered, or all SAME messages if
you do not enter any SAME location codes.
Weather Priority Mode
Weather Priority mode samples the specified weather frequency periodically
while scanning to see if the All Hazards 1050 Hz Warning Alert Tone (WAT)
is present. If the WAT is present, the scanner will sound an alarm and tune
to the specified weather frequency to monitor the nature of the alert.
To activate Weather Priority Mode, follow the steps above listed above in
Weather Radio Mode to find the strongest weather radio transmitter for your
area. Once the radio is tuned to the strongest weather radio transmitter for
your location, press the PRI key on the keypad. When in Scan Mode, the
radio will check the specified weather frequency periodically for the 1050
Hz Warning Alert Tone (WAT). If WAT is found, the radio will sound an alarm
and monitor the weather alert audio.
