Yep. We did all that this evening. Like I said - a dry run

Hi All,

I ran into a unrecoverable memory error at 007B today, but next to that I suspect some more memory issues.
Before the memory error occurred already, when I looked at the tool table, the DT command shows very weird values (see attached picture)
Also the parameters and the BL values were lost which I have to re-enter every time the machine starts (looks like at least a broken backup battery)

Would a zero memory procedure be sufficient here or would these issues mean a new CPU board?

Any help is very much appreciated

I got some really weird stuff on the screen after I pulled the memory board out to replace the battery. It took a few restarts before I could even get it to start up so I could zero the memory.

I would definitely try the zero memory procedure. I would also recommend replacing the memory board battery if you don't know how old it is.

This video shows how to replace the battery.

Hi All,

Thank you so much for the advice.
I ran the zero memory procedure and everything is back to normal again.
The battery most likely will need to be replaced soon, so that's high on my todo list.

Best regards & thanks again
