Hi,

I have an old VF-0 11/94 and because of CRC error, we decided to change the battery............
Before we do that we back up the parameters on pc via RS-232.
After the whole story of changing the battery, we end up with no parameters and a frozen screen with OFFSET CRC ERROR and tha HAAS logo and no keyboard working in that stage.
If I power up the machine with the PRGM\CON button pressed it boots in DOS, the keyboard is working but I don't know any commands.

Please Help.
