8563E Err 704 help

Hello!

  I have a spectrum analyzer that has started powering up with "err 704". 

  I am missing the service manual, but I have the manual that lists the error codes.  The information for "Err 704" states:  "checksum error of customer preselector peak data, external preselector data recalled in internal mode, or internal preselector data recalled in external mode"

  So far we haven't noticed the unit actually messing up other than the error message showing up. 

  Does anyone have any experience with this issue or know the most likely culprit for this error?

Thanks in advance for any helpful information!
