PART II
1 Parameter
The parameter overview is help a sought-after parameter for finding fast and changing. The construction of the list
has already been explained in the list using structure.
There are parameters, which can be found in the technicians' and developers' level both different consequences,
however, have. All settings in the developers' level aren't accessible for using staff and service technicians but are
adjusted by the software developers to the certain hardware once.
