4.3.1 Input options with the multifunc-
tion button
The multifunction button (see Fig. 27) is an
all-purpose "operator device" that, together
with the display, offers new possibilities for
machine operation.
4.3.2 Operating principle
To operate a machine via the display and
multifunction button, the machine functions
are displayed in the form of lines of text
(menu) or graphically in the form of picto-
grams. By displaying a certain text line or an
individual pictogram with brightness/color
highlighting or by means of a cursor, a cer-
tain function is highlighted – the highlighted
function is in "focus". Use the pointing device
(e.g. computer mouse, track ball, touchpad)
to move the focus from function to function,
i.e. to select a certain function. To execute
the function, confirm the selection by either
briefly pressing a button once (click), briefly
pressing a button twice (double-click) or hold-
ing and pressing down a button.
The multifunction button
can be moved along
four axes. The following functions are allo-
cated to the movement axes:
Turn button
During rotation, the rotary knob snaps into 20
positions per rotation. When the knob is
turned forward or backward by one or more
notch positions, the focus is moved forward
or backward in individual steps, i.e., a func-
tion is selected or settings (numeric values)
are changed, e.g., preset speed for the diesel
engine.
