Weather Alert
In the event of severe weather condi-
tions, the National Weather Service
broadcasts a special 1050 Hz tone. The
TRC-446 sounds this tone if it is turned
on and
CB/WX/PA
is set to
CB
or
WX
.
The tone does not sound if the radio is
set to
PA
. When the radio receives this
signal tone, WX/ALERT lights orange
regardless of the position of
CB/WX/PA
.
NOAA transmits this tone for 5 to 10
seconds. If the TRC-446 is set to
CB
or
PA
, the orange light remains on even af-
ter transmission ceases. You do not
have to be present when the signal is re-
ceived to be aware of an alert.
However, WX/ALERT turns off if you
turn to
WX
or move out of the range of
that NOAA channel. To turn off the indi-
cator you can also turn power off, then
on.
The orange indicator means switch to
WX to hear special severe weather in-
formation and warnings.
