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 PASSPORT is
programmed with safety radar decoding
OFF. If Safety Radar is used in your area,
your PASSPORT will display these signals
as K-band radar signals instead of safety
radar unless you use the Preferences to
turn PASSPORT’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 PASSPORT 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 PASSPORT’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.
