Detection Technology
How Safety Radar Works
From the factory, your Road Tech 75 is programmed with Safety Warning Sys-
tem (SWS) decoding OFF. If SWS is used in your area, your Road Tech 75 will
display these signals as K-band radar signals instead of safety radar unless
you use the EZ Programming to turn Road Tech 75’s SWS decoding ON.
The SWS safety radar system has 64 possible messages (60 currently allo-
cated). The SWS messages displayed on your Road Tech are listed below.
NOTE
Some of the safety messages have been condensed, so each message can
be displayed on one or two screens on Road Tech 75’s eight character display.
Since SWS is relatively new and the number of transmitters in operation is not
yet widespread, you will not receive SWS alerts 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.
