Hey, thanks a lot for leaving the solution!
Had exactly this issue today, the battery went and caused errors 6 and 10.
The manual is not very specific about this error, only showed something like "Internal special tables for option xx have been lost".
I was starting to have Vietnam flashbacks, my gosh it's gonna take 2 days and 400 calibration steps!
Thankfully all it needed was Shift+Special+68+Enter.
40 seconds later, done!
