I had an experience I wonder if anyone else has had. While driving down the expressway, my XTR 695 started to alert X band. This happened at a place where I never get false alarms. Over the hill, I saw a DOT work truck with it's flashers on. Now, whenever I've passed these trucks in the past, I'd get a K band alert from them. I really didn't think much of it, though.
When driving home that same day, I passed by a KNOWN K band speed measuring trailer, and again, my XTR alerted X band. Hmmmmm.....this time I made note of it.
The following day, as fate might have it...again I passed a DOT truck with it's flashers on, and again I was alerted to an X band. This time, however, I turned off the RD with its switch, and turned it back on. When coming home, I passed by the same speed trailer as the previous day, and my RD alerted properly with the K band. It seems turning off the RD with its switch allowed it to reset itself? Why didn't this happend when I turned off the car and thus the power to the RD?
