test the alarm 5 times in a row now and see if it works. If it does, maybe you have the same problem as many people: alarm goes off and you turn it off so quickly it doesn't even register...within seconds you are sawing logs again! I knew a guy who always had alarms that "didn't work". Now he puts his alarm on the other side of the room, requiring him to get up to turn it off, and guess what, his alarm works all the time now! The other thing that I've done is set the alarm for 5 p.m. rather than 5 a.m....man that sucks, especially when fishing was on the agenda.
