Pristine 3585a analyzer, unhappy calibration errors 02, 07

I found this beautiful, pristine clean 3585a whose only problems are

"calibration error 02" at any sweep width


"calibration error 07" at sweep widths less than or equal to 100kHz.

Does anyone know what these mean, or could suggest a place to begin looking.  I'd really like to save and preserve this excellent instrument in top notch operation.

Someone suggested the power supplies might be slightly out of regulation.

Any ideas or help appreciated!
