My alarm beeps at every loud noise or slight vibration when its set. I can un-arm then reset and it starts all over again. Just last night it started beeping one single beep about every 2-3 minutes for no reason. I had to pull the fuse to get it to stop. Now I have to push the kill switch over ride to start it. I am not a slim guy any more so it's getting a little ( ok..... A LOT ) uncomfortable to start. Is there away to set the sensitivity ? Under the dash is a black box with what looks like an adjustment knob ( small, round white knob with a slot for a screwdriver ) on it. What is that for? It says something about I.R. code on it...
