what mode do you use? I'm asking because I've used autoscan since I've got it, and I'm worried about the sensitivity on it. today while at work I noticed a cop sitting in the parking lot across the street from me. since my job is slow and boring (video store) I went to my car to turn my RD on just to see if he was using radar. it took about 3-4 seconds for it to react after I turned it on to the cops ka band. btw, I'm using a bel rx55, and now I have it on highway mode.
