Scan Mode - West Marine VHF490 Owner's Manual

Scan Mode

You can save channels into memory and then use scan mode to monitor those channels. When the radio detects a signal on a
channel, it pauses on that channel as long as the signal is received; when the transmission stops, the radio will continue scanning.
In scan mode, you can get the following information from the display (some indicators will not always be displayed).
Using the radio in scan mode
• You cannot transmit while in scan mode.
• You must have two or more channels in memory to start a scan.
• To save a channel into memory, select the channel, then press and hold WX-MEM for two seconds. Memory will show on the
display.
• To remove a channel from memory, set the radio to that channel, then press and hold WX-MEM for two seconds. Memory will
no longer show on the display.
• To activate scan mode, press and hold CLR-SCAN. Press and hold CLR-SCAN again to return to the previous mode.
• When the radio automatically stops on a channel, press CHANNEL UP to leave that channel and resume scanning.
• To end the scan, press the microphone' s PUSH TO TALK, CALL-MEM, or WX-MEM buttons. The radio remains on the last
scanned channel.
Scan mode with Weather Alert Watch
If you activate Weather Alert Watch while operating in scan mode, the radio checks the most recently-used weather channel every
seven seconds, then continues scanning the next channel in memory.
To turn Weather Alert Watch on or off, press and hold CALL-MENU while the radio is idle. Select Setup and then WX-Alert Mode.
Use CHANNEL UP and CHANNEL DOWN to choose WX Alert Mode setting On or Off.
