6.5 NOAA WEATHER CHANNELS
In the event of a major storm or other appreciable weather condition requir-
ing vessels at sea (or other bodies of water) to be notied, the NOAA (Na-
tional Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz
tone which the HX400IS can detect and alert you of pending storm warnings.
The 1050 Hz tone, when detected, will produce a loud beep in the speaker of
the HX400IS, to signal that a Weather Alert Broadcast is being received.
1. To receive a NOAA (National Oceanic and Atmospheric Administration)
weather broadcast, press and hold the
key. The
transceiver changes to the weather channel mode
and recalls the last used NOAA weather channel.
This mode consists of a preset memory bank contain-
ing 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 key. The
transceiver will revert to the channel you were using prior to switching to
the weather channel mode.
6.5.1 NOAA WEATHER ALERT
In the event of extreme weather disturbances such as storms and hurri-
canes, 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
key to
stop the beep tone and listen to the weather reports.
6.5.2 NOAA WEATHER ALERT TESTING
In order to test this system, NOAA broadcasts the 1050 Hz tone every
Wednesday sometime between 11 AM and 1 PM local time. You may use
this opportunity to test your HX400IS periodically to conrm that the Weather
Alert feature is working, or for training crew members on how to congure
the HX400IS to receive the NOAA Weather Alerts.
