Controls and input methods
Tabs
Tabs divide up the functions of the coee machine. They act as the main menu level. Clicking
on a tab symbol takes the user to the corresponding menu. The meanings of the symbols are
explained in „Übersicht der Registerkarten im Menü Service“ auf Seite 10-8.
Input buttons
Input buttons either trigger an action directory or take the user to a lower-level menu. Most menu
windows feature an X symbol [0] in the top right corner, which is used to close the window. To
make things clearer, the X symbols are not shown on the windows in this chapter.
Parameter elds
Parameter elds are used to display or change texts and parameter values. Some elds, such
as checkboxes, can be modied directly by clicking on them. With other elds, clicking on them
opens another window, where the corresponding values for the eld can be adjusted and then
saved. Values can usually be entered via a keyboard window [1]. If a button is pressed for longer
than 1 s, the special characters assigned to it appear. "Suggestion lists" [2] have been created
for more complex elds; the user can select the value they want from this list and then save it.
For optional settings, an option selection window [3] opens.
Graphical controls
With graphical controls, values can be changed directly using the on-screen symbol (example)
[4]. Change the values by tapping or moving the elements, for example.
