How SWS Works
There are two separate Safety Radar
systems in limited use today: Safety Alert,
and Safety Warning System (SWS). Both
systems use modified K-band radar signals.
From the factory, your RX45 is
programmed with safety radar decoding
OFF. If Safety Radar is used in your area,
your RX45 will display these signals as K-
band radar signals instead of safety radar
unless you use the Preferences to turn
RX45’s safety radar decoding ON.
The Safety Alert safety radar system
has three possible alerts:
• Safety Vehicle
• Road Hazard
• Train Nearby
The SWS safety radar system has 64
possible messages (60 currently allocated).
The SWS messages your RX45 can display
are listed on the facing page.
NOTE: Some of the safety
messages have been condensed, so
that each message can be displayed
on one or two screens on RX45’s eight-
character display.
Since Safety radar technology is
relatively new and the number of
transmitters in operation is not yet
widespread, you will not receive Safety
signals on a daily basis and should not be
surprised to encounter emergency
vehicles, road hazards and railroad
crossings that are unequipped with these
transmitters and, therefore, fail to provide
a signal.
As Safety transmitters become more
prevalent (the number of operating
transmitters is growing every day), these
Safety radar signals will become more
common.
