I am a owner of an VMC-855 Machining Center.

I had been away from my workplace for some time so the machine was off all the time and when I got back and tried to turn my machine on, the fans were working but the screen/menu wouldn't open, it would just stay on a blank page with a blinking input line.

I have been told that the machine's code may be gone due to inactivity. Please help me regarding this issue.*

Thank you!
