Safety Warning System
®
(SWS
™
)—What is it?
The Radio Association Defending Airwave Rights, Inc.
(R.A.D.A.R.) conceived and developed the Safety
Warning System
®
. The concept behind this system is
to warn motorists of potential road hazards by
employing Safety Warning System
®
transmitters in areas
such as construction zones, accident sites and
detours. These SWS
™
transmitters operate within
the 24 GHz portion of the K band frequency, and
broadcast uniquely coded signals that are detected by
your unit.

Interpretation of Alerts
Radar Alerts
The alerts provided by your unit are affected both by
the type of transmission (continuous wave or instant-
on), and the position of the Radar source. Generally,
when you drive closer to a Radar source, the intensity
of the received signal increases, resulting in the
increase of the number of bar graph segments as well
as numerical digit

and a corresponding increase
in the audio alert rate. Described below are five
common types of Radar encounters and the alerts
you will typically receive.

Stationary or moving Radar,
straight ahead or aimed in your direction
Since Radar signals travel in a straight line, this
Radar encounter potentially offers maximum warning
range. Once the signal is received, the initial warning
consists of an X, K or Super Wideband Ka audio
