After I installed my ALP system with three heads in the front and custom settings,ie:silent start up, dim LED, Loud alarm I was very satisfied. However, now whenever I start up I get a voice message...WARNING restore defaults and memorize sensors. Then it goes to blue mode. I dont have a lazer tester but I do get a parking alert on each sensor when I sweep my hand in front of them. My question is this just an annoying software glich or am I really at risk? I think it's just software. After all I did change default settings on purpose and all sensor are working at least for parking mode. Any comments appreciated Bill
