Weather

The NOAA weather channels now cooperate with the FCC to alert you of other hazards besides weather (child abduction alerts, nuclear, biological, etc.). In weather mode, the radio monitors one of the ten NOAA weather channels. If a weather alert signal is received in Weather Alert mode, the radio sounds an alert tone and the display blinks.

Using the radio in weather mode

xx You cannot transmit while in weather mode. xx To enter weather mode, press WX/SOS.

xx To turn off the radio’s alert tone, press any button.

xx To cancel weather mode and return to the previous marine channel, press WX/ SOS again.

Weather mode with Weather Alert Watch

If you activate Weather Alert Watch while operating in weather mode, it operates as a type of “sleep mode:” the radio stays on the weather channel and mutes the speaker. If an alert is detected, the radio sounds an alert tone and turns the speaker back on. This mode is very useful when you are anchoring for the night but want to keep informed of hazards.
