I recently started noticing my RX65 would stop alerting to all K band door openers, signs, and my RD K band tester, so naturally, I checked to make sure it was enabled. It was, as soon as I checked, it started alerting K band again (usual door openers and such). Then it has started doing the same thing again, no K band alerts, and it takes about 2-3 seconds to alert for laser (from a laser tester), thanks for making the device GOL!. This has become a regular problem lately, and not sure how to fix it. I dont know when it stops detecting K band because of course I dont have a "scanning dot" or anything indicating its "alive". I bought it from Radar Roy and its within its 1 year warranty. Maybe I should send it back to BEL? Any ideas on whats going on?
