Maybe anyone of you know an idea to delete or reset this password?

Page 78 of the manual (298 pages) discusses enabling or changing the password. It looks as though you need to know the password to disable the password.

There may be a factory reset button somewhere.

Or, this may the kind of appliance that resets if you disconnect power for several days.

Unfortunately i didn't find any reset button, here is some jumpers but without clearly description. Also unit was off from power around one month,
