I have had the 06045 lighting detector for about a month. I have it paired with the HD display. I get a warning yellow light and a warning on the HD display of interference while the red lightning banner is displayed. I have moved the sensor all over the yard, and still get the same yellow light. It is not constant, but erratic. Maybe once every 15-30 mins. I live in the timber, in the mountains with no "close" neighbors. I have the sensor about 25 feet outside and in clear view of the HD display through a sliding glass door. I have also tried all 3 channels, with no improvement. I also notice the green light blinks on the 8 sec interval regardless of the outside weather. Sometimes the green light flash with be significantly dimmer than the normal flash. During lightning yesterday, the lightning would have to be pretty close for the detector to catch it, and even then only caught about half of the flashes/thunder that I heard in person. I did get a yellow light simultaneously with the red light flash on a lightning strike. Almost like the strike caused the interference led to light up. Not having any other experience with a lightning detector, does this sound normal or did I get a defective sensor? I have a few days left to exchange it if it sounds goofy.
