the alert is issued. When the designated time has passed the display message and LED will be reset to their normal state.

Reviewing Overlapping Alerts

The 74-250 radio can store up to five different alerts (with overlapping effective times) in its memory. If the radio receives a new alert while a previous alert is still in effect, the radio automatically displays the alert description and sounds the alert for the new alert message. To scroll backward and forward through the radio’s memory and review all the effective alerts, press the “UP /DOWN” Buttons. Each alert will be displayed with the time it was received.

When a Test or Demo Alert Occurs

To find out the test schedule of for your area, contact the local NOAA or NWS office. Look for the number under US Government, Department of Commerce.
