k Safety Warning System ® (SWS )—What is it?The Radio Association Defending Airwave Rights, Inc.(R.A.D.A.R.) conceived and developed the SafetyWarning System ® . The concept behind this system isto warn motorists of potential road hazards byemploying Safety Warning System ® transmitters in areassuch as construction zones, accident sites anddetours. These SWS transmitters operate withinthe 24 GHz portion of the K band frequency, andbroadcast uniquely coded signals that are detected byyour unit.IInterpretation of AlertskRadarAlertsThe alerts provided by your unit are affected both bythe type of transmission (continuous wave or instanton),and the position of the Radar source. Generally,when you drive closer to a Radar source, the intensityof the received signal increases, resulting in theincrease of the number of bar graph segments as wellas numerical digit 1- 9 and a corresponding increasein the audio alert rate. Described below are fivecommon types of Radar encounters and the alertsyou will typically receive.1. Stationary or moving Radar,straight ahead or aimed in your direction20Since Radar signals travel in a straight line, thisRadar encounter potentially offers maximum warningrange. Once the signal is received, the initial warningconsists of an X, K or Super Wideband Ka audio
