Prob a safety driven issue which is prob not a bad thing. It's amazing to have a charger that looks out for itself. Just takes some getting used too - if 0610i Net/Duo had a well documented manual that mentioned this kind of stuff it wouldn't make it as bad.

My only clue was the new firmware and the error - last pg on 'manual' said the msg meant battery not connected. So I started to suspect the output leads I was using.
