POP is a feature of certain radar guns that is intended to defeat radar detectors. It emits radar in very short bursts - on the order of 67 miilisecods - to take an initial reading of your speed so quickly that the radar detector doesn't have time to recognize the presence of radar and signal an alert. Presumably the police officer can use POP on a series of cars without any radar detectors ever knowing that it's being used. That initial reading is not very accurate, but if it shows you are probably speeding the officer switches his radar gun to standard mode to get a longer and more accurate reading of your car's speed. Of course now your detector will indeed react, but since he's already got you in his sights you are nabbed before you have time to slow down.



Radar detector manufacturers have responded by setting quicker reaction times to the initial burst of radar energy. Thus if POP is used on a car in front or behind yours, your detector will sense it and signal a warning - hopefully before the officer aims it at you. But this change has the adverse effect of causing more false alarms from noisy devices such as commercial alarm systems, radar detectors in other cars, and Audi's Side Assist feature. The culprit is the Audi Side Assist warning system, not park distance control (not sure, but I think all park control systems use high frequency sound, not radar). It interferes with your V1's POP feature, and unfortunately for those of us who own an Audi you can't turn it off (there's a switch that turns off the alerts, but the radar system still stays active). So when I first used my V1 in the Audi it was going off continually. The solution is to disable the POP feature in the V1. If you want to try it see: http://www.valentine1.com/Lab/techreport3.asp - you would disable feature "J."POP is a feature of certain radar guns that is intended to defeat radar detectors.
