D D Weather alert
A 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
the "WX ALT" indicator blinks until the transceiver is operated.
The previously selected (used) weather channel is checked
any time during standby or while scanning.
• "WX ALT" appears instead of "WX" indication when the function is
set ON.

If a distress signal is received on Channel 70, the transceiver

DSC watch pauses until the signal disappears.
This function may not be available for some channel
groups depending on dealer setting.
