Hi everyone,



I am an independent biomedical service technician. I have a client with a "MAICO easyTymp" handheld tympanometer showing a "Calibration Overdue" message on startup.



The local dealer's calibration/service fees are extremely high for the client, so I am looking for an alternative solution to bypass this message or reset the annual calibration counter independently.



Could anyone share or sell the Maico Service Software, or provide the Service Menu Password/procedure required to clear this error?



Device Details:

- Model: MAICO easyTymp



Any help, software links, or technical advice would be highly appreciated.



Thank you!

Equipment: Maico easyTymp
