Access code to change the access levels in eurotherm 2416

I am currently facing the problem to change the ACCESS LEVEL. Based on the manual, the code should be either 1 or 0, but both don't work to access the GOTO display.

Is there anyway to reset the code or others?

In addition, ultimately I would like to change the highest temperature limit. Can you let me know how to do it?
