Hi,

I don’t know the machine but looking at the service manual the backup battery is a CR2032 T34 battery (supplier example only) that is soldered onto the Control board. Just search for CR2032 T34 to find suppliers that suit you best

You would have to disassemble the machine to access the Control pwb board - see p.36 of the manual. Check how the battery is connected before unsoldering it from the board so that you install the new battery in the same way, as its polarity is important.

Also be aware that on p.72 it states:

Shading paper:

The white and black basis is applied to remember the shading wave-form. Be sure to perform this operation when replacing the battery or replacing the control PWB. Execute in the shading mode of DIAG mode. (See p.11 of the manual for how to enter the Diagnostic mode - Shading mode is Item #8)

Hopefully this is of some help.
