    Maho Graziano GR200E lathe, Philips 432T problem with the start

    I bought a Maho Graziano GR200E lathe with a Philips 432T control, the machine is in perfect technical condition, only 2700 hours of work, but the backup battery only had about 0.5V instead of 6V. I assume that the machine parameters have been lost. After starting, the machine performs a POWER-UP CHECK and according to the instructions, after this test is completed, it should automatically go to MANUAL REF.POINT. Unfortunately, it stops at POWER-UP CHECK (see photo) and nothing can be done, all buttons on the desktop are inactive. How can I go further or complete the machine parameters?

    The machine is very old (beginning of the 90s) but it is so perfectly preserved that I would regret scrapping it so I decided to repair it.

    Update, after switching the button in the wardrobe I was able to enter the MACHINE CONSTANS preview, as you can see they are all incorrect. How do I enter them manually? I will also add that the buttons on the keyboard work bad, i.e. for example I press 1 and it appears 3 or nothing at all.
