They have their very own website now,
www.concertone.com, where you can buy a new unit- if desired, or you can contact them to discuss the problem. From what I've heard of the ZX 75, a LOT of folks have problems with that alarm going off on a daily basis, with no way to stop it. I have the ZX 600,(no alarm, AM/FM/CD-DVD surround sound w/sub) I've replaced it once, and it's been good ever since. Good luck, Randy
