)—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

transmitting devices in areas such as construction zones,
accident sites and detours. These sws

transmitters operate

broadcast uniquely, coded signals which are detected by your
EXPRESS 925.
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 a higher number appearing in the Digital Display
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.

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 the X, K
