Note
Access authorization
If access rights have been assigned for functions and the protection level is "less" than that
assigned, then the softkey is not displayed in the operator interface and the function cannot
be called.
This applies to all functions. If for example, the "Tool cabinet" function is barred from
operation, then its softkeys are not displayed.
