Technical Details
How Safety Radar Works
Safety Warning System, or SWS, uses a
modified K-band radar signal. 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.
From the factory, your Passport is
programmed with SWS decoding OFF. If
SWS is used in your area, your Passport will
display the safety messages associated with
the signal. If you wish to detect this system,
use the EZ-Programming feature to turn
Passport's SWS decoding ON.
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 rela-
tively new, and the number of transmitters
in operation is not yet widespread, you will
not receive Safety signals on a daily basis.
Do not be surprised if you encounter emer-
gency vehicles, road hazards and railroad
crossings that are unequipped with these
transmitters. As Safety transmitters become
more prevalent (the number of operating
transmitters is growing every day), these
Safety radar signals will become more
common.
