Technical Details ALERT EXPLANATION V945 receives weak signals. These signals may be a little stronger as you pass large, roadside objects. The signals increase in frequency. A moving patrol car with continuous radar is overtaking you from behind. Because these signals are reflected (reflections are increased by large objects), they may or may not eventually melt into a solid point even when the patrol car is directly behind you. V945 alerts slowly for awhile and then abruptly jumps to a strong alert. You are approaching a radar unit concealed by a hill or an obstructed curve. V945 alerts intermittently. Rate and strength of alerts may be consistent or vary wildly. A patrol car is traveling in front of you with a radar source aimed forward. Because signals are sometimes reflected off of large objects and sometimes not, the alerts may seem inconsistent. V945 alerts intermittently. Rate and strength of signal increases with each alert. V945 gives an X-band, or K-band alert intermittently. A patrol car is approaching from the other direction, sampling traffic with instant-on radar. Such alerts should be taken seriously. You are driving through an area populated with radar motion sensors (door openers, burglar alarms, etc.). Since these transmitters are usually contained inside buildings or aimed toward OR away from you, they are typically not as strong or lasting as a real radar encounter. CAUTION: Since the characteristics of these alerts may be similar to some of the preceding examples, overconfidence in an unfamiliar area can be dangerous. Likewise, if an alert in a commonly traveled area is suddenly stronger or on a different band than usual, speed radar may be set up nearby. 17
