I have an XTR-690 rev C. I understand that the X and K bands are swept together, then it looks for a high or low, then decides which band to alert to. My problem is this: On the highway, I pass a K-band construction sign, then after that there are three X-band falses (door openers) in the next 1.5 miles. The 690 hangs on to K-band and alerts K-band at those locations (even though they are X). Kinda annoying. As one member suggested, I turned off X-band but it didn't help at all. So to verify that there is X-band at these locations I temporarily turned off K and the 690 alerts to them as X. The next day I used my X50 to again verify that they are X band. The reason behind this design is to eliminate "rapid switching" between X and K. I don't get it. I have not had a detector do that since I owned a Road Patrol XK. Does anyone else have this concern? Will the XTR-695 use this same technology? Is there anything that can be done? Don't get me wrong, I think this detector is cool and is superior in alerting to Ka, I just don't care for the X and K combined sweep method.
