5.6.2 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requir-
ing vessels at sea or other bodies of water to be notified, the NOAA (Na-
tional Oceanographic and Atmospheric Administration) broadcasts a 1050
Hz tone that the HX370S can detect. (Refer to section 5.6.1 “NOAA WEATER
ALERT” on how to use this feature.) This tone, when detected, will produce
a loud beep from the radio speaker to signal that a weather alert is being
broadcast.
In order to test this system, the NOAA broadcasts the 1050 Hz tone every
Wednesday, sometime between 11 AM and 1 PM. Any marine VHF radio
that can detect the weather alert tone, may use this test to verify that this
feature is functioning properly.
NOTICE
Take care not to damage your hearing when operating with the optional
VC-24 VOX Headset or Earpiece. The NOAA Weather Alert Tone will be
emitted at full volume, irrespective of the setting of the POWER/VOL-
UME CONTROL knob.
