Error code 4 on original AlphTrak meter

[Larry and Kitties]

What does error 4 mean? I can't download a manual. I can get a link to the manual but it says 4040- Not Found

Larry,

I found this thread on another blog. It doesn't look like it's terribly clear what error 4 is.

Thanks, the answer was the last post, weak battery. Replaced battery and all is fine.
