Using the All Hazards/Weather Radio
Your radio functions as an all hazards/weather warning radio. This is
especially useful when your area is expecting severe weather conditions
any time of day. It emits a loud tone whenever your local NOAA weather
station broadcasts a severe emergency tone. You have the option of
listening to the emergency/weather broadcast or not. Even though you
may not be listening to the broadcast, the radio still responds to the
emergency tones from the local weather station.

Testing the Weather Alert Radio
NWR stations conduct regular tests of Alert broadcasting. Tests normally
occur on Wednesdays between 10AM and 12PM unless threatening
weather is occurring. Your local station can be contacted to find out
exact dates and times of tests.
You should make sure your WX500 receives these Test Alerts in its
installed location. This is very important because an emergency alert
broadcast might not trigger your radio even when it seems to be
receiving broadcasts fairly clearly....
