Hidden calibration menu Indo-AIT Practica edger

Hi, my first post here!

Anyone knows how to access to hidden menus? I need to calibrate the probes in Practica, and there is no option for that in normal menu

All the screens I can see are these ones:

I know there is a combo, pressing STOP button while machine turning on, but there is nothing there to calibrate the probes

Any help is appreciated...
