I had same problem at one time and had to send the unit back as the problem involved broken battery connections.

I tried other new batteries. I tried leaving the batteries out for a while. I tried reset, and still nothing. I have had my bookcourier for 3 years now without a problem. Anyone out there have anything else I can try? Thanks Aerial Gilbert
