MS 510 time setting after every power on

[i-have-fax-problems]

Hello,

I have an older MS510 which shows time input after every power on.
Is there a battery which is defect or what can I do. All other data are
not lost only the time must be set, which was not the case in recent years.

I would start by replacing the lithium battery on the control board. We only see a Lexamrk lose the date-time when they have sat unlpugged for very long periods of time.
