Using the Weather Channels
The radio receives ten National Oceanic and Atmospheric Administration weather channels. Although the radio receives all ten, one channel will be received best due to your geographic location.
1.Press WX/ALERT to activate the weather band. The screen displays
Weather Band at the upper left and the channel number. The
frequency of that channel number appears at the bottom of the screen. You can find a complete listing of the weather channels in the Reference pages.
Use ▲ or ▼ to change between WX channels. You will receive one channel in your area better than all others.
Note: the radio’s memory retains the channel that appears when you switch to WX mode in memory 
when you turn off the radio.
. To switch to the Alert mode, press and hold down WX/ALERT for about 2 seconds. WEATHER
ALERT MODE ENABLED scrolls along the bottom of the display.
If the radio receives a weather alert by means of either a S.A.M.E by decoding the entered FIPS code or if the radio is in the marine channel mode, detecting 
the 1050Hz tone, the radio sounds an alarm and displays an alert message at the bottom of the screen, such as
HURRICANE WARNING.
