Guide :Vehicle Parts & Accessories : BEL 915R Radar Detector
Start up beeping with lights
When the radar detector is turned on with the car first thing in the morning after being off all night the detector goes through its normal start up testing, but then every 3 seconds there is a single "beep" with the X,K,Ka lights lighting up for a single flash. this goes on for about 30 seconds then stops and then the radar seems to be functioning normally. Any ideas?
