6.8 NOAA WEATHER CHANNELS

1. To receive a NOAA (National Oceanic and Atmospheric Administration)
weather broadcast, press and hold the [ CLR ( WX )] key.
The transceiver changes to the weather channel mode,
and recall the last used NOAA weather channel. This
mode consists of a preset memory bank containing the
NOAA weather channels.
2. Press the [ ] or [ ] key to change to other weather channels.
3. To exit from the weather channel mode, press and hold the [ CLR ( WX )]
key. The transceiver will revert to the channel you were using prior to switch-
ing to the weather channel mode.
6.8.1 NOAA WEATHER ALERT
In the event of extreme weather disturbances such as storms and hurricanes,
NOAA sends a "weather alert" consisting of a 1050 Hz tone, followed by weather
reports on the weather channels.
When a "weather alert" is received on a weather channel, the transceiver emits
a beep tone. Press the [ CLR ( WX )] key to stop the beep tone and listen to the
weather reports.
Four options for the Weather Alert feature are available, refer to section
"8.10 WEATHER ALERT" for details.
6.8.2 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requiring
vessels at sea (or other bodies of water) to be notified, the NOAA (National
Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone
which the HX851 can detect and alert you of pending storm warnings (refer to
section "6.8.1 NOAA WEATHER ALERT" for a discussion of how to use this
feature). The 1050 Hz tone, when detected, will produce a loud beep in the
speaker of the HX851, to signal that a Weather Alert Broadcast is being re-
ceived.
In order to test this system, NOAA broadcasts the 1050 Hz tone every Wednes-
day sometime between 11 AM and 1 PM local time. You may use this opportu-
nity to test your HX851 periodically to confirm that the Weather Alert feature is
working, or for training crew members on how to configure the HX851 to re-
ceive the NOAA Weather Alerts.
