:? Hi. Just got a Snooper S5r which is working fine, but tonight on the way home I passed a cell phone mast and it gave its normal little beep, a few seconds later it started again until it was reading between k4 and k5. The only thing I could see was the headlights of a car behind me. Could this have been a police car with a radar on me even though my detector is faceing the front of the car, or something else. It went back to its normal state once the other car went off in a different direction???
