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 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. 1. Stationary or moving Radar, straight ahead 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 Wide band Ka audio alert coupled with simultaneous identification of the Radar band (X, K or Ka) and signal strength in the Text Display. The number of bar graph segments displayed depends upon the strength of the signal received. As the strength of the Radar signal increases, the audio alert becomes more rapid and the bar graph will display the maximum number of five segments to indicate maximum signal strength. Assuming the Radar signal remains uninterrupted, the audible and visual alerts will clearly indicate a "weak" signal becoming stronger as you drive closer to the Radar source. Remember, when the police Radar source is moving toward you, the Radar signal strength will increase much more rapidly than if you are approaching a stationary source. 
