Get this, every Sunday early, early morning at 3:00 a.m. my 750 alarms 5 to 6 times with the weirdest sounding alarm I've ever heard - it sounds like a wounded animal. For a couple of weeks I thought my house was haunted. Scared the crap out of me. There is nothing set for that time and the only message is "Alarm: X". Anybody know how to turn this off?? - I've already reset. All I know to do is make sure I turn the blasted thing on vibrate to keep from getting woke up on Sunday's at 3:00 a.m.
