8.1.2 Menu keys
The menu keys allow you to directly access the first menu level (Operation 1-x-x-x,
Diagnosis 2-x-x-x, Settings 3-x-x-x, and Information 4-x-x-x).
The parameter numbers contain the navigation path, which helps you find a
particular parameter quickly and easily. The first digit of the parameter number
indicates the first menu level, which is called up directly via the four menu keys.
