I have a new single head LPP installed in the lower center of the main grill of my Silver Infiniti G35. I was driving along in Silver Spring MD with a coworker in the car talking about buisness and not exactly paying attention to the PSL which was 30mph. I get an alert, first ever, so it took me a second to realize what it was and hit the brakes, IIRC I was doing 40ish. The alert continued for a while (perhaps a 3-4 seconds) then I saw a motorcycle LEO with a PLIII on the sidewalk perhaps 200' ahead of me, he was not pointing the PLIII at me anymore, but was holding it down looking at the control panel. When I passed by him I looked in the rearview and he was certainly watching me as I passed and watching me drive away. I estimate I was at about 500' when the LEO first shot me and the LPP allowed me enough time to slow down. So I beleive it worked... Would I get a ticket for 40 in a 30 in MD anyway, more than likely yes I would.
The one answer I need is does the LPP turn the audible alert off when it no longer detects laser? Or does the audible alert turn off after the 8 second shut down period is reached. I cant recall because I was so freaked at the time, but I think the audible alert stopped then before 8 seconds was reached. I did hear the LPP reset when it came back on, so I know it did turn off and back on again.
