2.1.7 Main Menu Mode
Select main menu mode by pressing the [Main Menu] key. The readout
below appears on the display.
The middle and bottom sections on the display show a list of parameter
groups which can be chosen by toggling the up and down buttons.
Each parameter has a name and number which remain the same regardless of the programming mode. In main menu mode, the parameters are divided
into groups. The first digit of the parameter number (from the left) indicates the parameter group number.
All parameters can be changed in the main menu. However, depending on the choice of configuration (par.1-00
Configuration Mode ), some parameters
can be hidden.
