DPO70604B Calibration Procedure issues

I'm having some issues when running calibration procedure on my DPO70604B. While running the calibration on the unit, the screen shows that it is "Running FDC" then immediately fails following this message. I'm not sure what the 'FDC' means and am wondering if this could be the issue, as I have tried the calibration multiple times with the same outcome.

Hello Joshua,
Assuming this is the SPC calibration from the Utilities menu, disconnect all inputs, adaptors etc., do a default setup then run.

If still failing SPC, there is a hardware failure and a repair will be needed.
