the signal received. As the strength of the Radar signal increases, the audio alert becomes more rapid and the flashing of digit #3 or #4 or the flashing of all leds (left to right) will occur. This indicates a 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. . Stationary Radar aimed around a corner Under this circumstance, reaction time is considerably reduced. Since the Radar signals are transmitted across your line of travel, there is generally no signal available to receive until you are relatively close to the source. Once an alert is received, expect the strength of the signal to increase very quickly. Advanced warning in this situation may be reduced. . Stationary Radar concealed by the crest of a hill aimed in your direction. Radar signals travel in a straight line and do not pass through  earth. Consequently, police Radar aimed at the crest of a steep
