ESG E4432B Attenuator Repair Question

My E4432B developed a defective section in its output attenuator, so I replaced it and after recalibration the ESG is working fine. I notice that on the "Instrument Info" page, the attenuator cycles counter did not revert to zero after I installed the new attenuator, and I couldn't find any information about zeroing that counter in any of the service documentation.

Is it possible to reset the attenuator cycles counter, and if so, how?
