Information

When CB/WX is on WX position Weather Receiver
is activated.

Place CB/WX Switch in the WX position.
Turn the Weather Channel Selector (1-7) until
you find the Weather Channel with the clear-
est reception. Sometimes more than one
channel can be received, however, the closest
broadcast to you will be the one with the
clearest signal.

Note

For a list of weather frequencies

Transmitter locations, contact
your nearest National Weather.

Service Office, or write to:

For ideal weather reception use
a dual band antenna (center

What You Should Know About  Weather

If threatening weather is nearby, the National
Weather Service may broadcast a 10 second alert
tone. This tone will be heard through the CB, even
if the CB/WX Switch is in the CB mode or the unit
is turned off.

This enables you to monitor CB frequencies and
still be warned by the National Weather Service
Emergency Alert. When you hear the aler t, place
the CB/WX switch in the WX position. You will
then be able to hear the Weather Warning
Broadcast.

You can completely disable the Emergency
Weather Alert feature by turning the Weather
Channel Selector to the     position.

Your 29 WX NW ST has a special auto squelch cir-
cuit for weather transmission which disables your
squelch control.

If you are using the CB mode, remember to
change the CB/WX Switch from CB to WX every so
often to make sure you are continually tuned to
the clearest/closest weather band channel in case
an alert is broadcast.
