LISTENING TO THE WEATHER 

BAND

The National Oceanic and Atmospheric Administration 
(NOAA) broadcasts local forecast and regional weather 
information on one or more of seven channels in the US. 
We have pre-programmed your CB with all seven of these 
frequencies.

To listen to a weather broadcast or alert, slide 

CB/WX

 to 

WX

Rotate 

CHANNEL

 to select a frequency.  

Ô

To verify reception, your radio must receive a test or 
emergency alert broadcast. The National Weather Service 
broadcasts a test alert every week. To find the specific test 
schedule in your area, contact your local NOAA or National 
Weather Service office.

When in CB mode, the radio automatically sounds an alert if 
a weather alert signal is detected. This is especially useful 
when your area is expecting severe weather conditions.

When your local weather station broadcasts a severe 
weather alert, the CB sounds a tone corresponding to the 
alert type and 

WX/ALERT

 lights.

 NOTE

PTT does not work when 
CB/WX is set to WX. You can 
only send transmissions when 
in CB mode.

You cannot transmit while WX/
ALERT
 flashes in CB mode.

The alert tones for a Test and 
EAT (Emergency Action 
Termination) sound very similar. 
We suggest you switch to WX 
mode immediately to listen to 
the weather broadcast.

Because of atmospheric 
conditions, you may receive 
signals that do not contain 
information relevant to the 
emergency level. This is normal.

The radio sounds an alert 
regardless of the channel 
setting.

The CB will not sound an alert 
while you are transmitting.

If you are in a rural or fringe 
area, your radio might be 
triggered by an alert broadcast 
in one area, but not be triggered 
if you travel to another area 
(even close by).
