Change the operating mode by marking the desired mode and pressing
the OK button. When an operating mode is selected it shows what in the
control module is permitted (crossed out = not permitted) and selectable
alternatives to the right. To select selectable functions that are permitted
or not, mark the function using the control knob and press the OK button.
