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.
