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 V955 can display are listed on the
facing page.
From the factory, your V955 is
programmed with SWS decoding OFF. If
SWS is used in your area, your V955 will
display the safety messages associated with
the signal. If you wish to detect this system,
use the Programming feature to turn the
V955’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
the V955’s eight-character display.
Since Safety radar technology is
relatively new, and the number of
transmitters in operation is not yet wide-
spread, you will not receive Safety signals
on a daily basis. Do not be surprised if you
encounter emergency 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.
