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?
