Testing the Weather Alert
Follow these steps to test the weather
alert — to hear how it sounds and en-
sure that the circuitry is working.
Note: This test does not ensure that
your scanner will sound an alert when
the weather service transmits an
emergency signal (see “Weather
Alert” on Page 25). Proper operation
is affected by the strength of the
weather service’s signal.

Traffic Safety
Do not wear an earphone or head-
phones while operating a motor vehi-
cle. This can create a traffic hazard
and can be illegal in some areas.
Even though some earphones and
headphones let you hear some out-
side sounds when listening at normal
volume levels, they still can present a
traffic hazard.
CONNECTING AN 
AMPLIFIED EXTENSION 
SPEAKER
In a noisy area, an amplified extension
speaker might provide more comfort-
