Weather alert

An NOAA broadcast station transmits a weather alert tone be- fore important weather information. When the weather alert function is turned ON, the transceiver detects the alert, then ﬂashes the “WX ALT” indicator until the transceiver is oper- ated. The previously selected (used) weather channel is checked any time during standby or while scanning.

•“WX ALT” appears instead of “WEATHER” indication when the func- tion is set ON.
