Customer has a DX-80, much has been replaced over the years. Phone time is correct. Still the original VM. It's not keeping time. Pretty erratic. Anything I can do? I just popped a new battery into the VM the other day. Doesn't seem to make a difference.

FYI Tech Support says this is a failing card that needs replaced or repaired

I have quite a few if you need one. PM me for details.
