Greetings, dear colleagues, specialists, professionals! I’ve created a topic here with a different problem, people helped me a lot and I am grateful to the whole community also.

Now I have a problem again that I can’t solve because in this case I’m doing what I didn’t study for. I am a process engineer, but I am also engaged in the selection of equipment, its purchase, I participate in the launch of machine tools for the family business.

Machine: Boehringer CM250, year 1997, CNC Siemens 840C, without driven tool and without tailstock. Problem: The memory battery ran out during shipping.
I'm trying to initialize (there is a process on the video)
In my opinion, everything is going well, except for the error at 9:52. I can be wrong, but in my opinion, because the drives on the machine are analog, not digital, the error does not mean anything bad. Again, I could be wrong...
I finish all the procedures according to the instructions and the machine offers to set zeros.
I have little experience, I do not know what to do next. In another instruction (I also did it, the effect is the same as on the video) it says that I should run the L965 program to set zeros, but there is no such program in the machine, just like there is no tool eye.

In the video with an attempt to initialize after the reset, I used the official instructions, it says nothing about the L965 program.
I tried to get the turret to the limit switches above the spindle and on the other side of the z-axis, pressed various buttons, spent a lot of time with this, but nothing comes out ...
I showed the parameters and two existing errors in videos (I don’t think that this is the case, since the machine was in working condition before shipping).

Can you please help, explain what I should do next, as for a beginner, and did I do the reset and initialization correctly?
