Touch display
The display can be scratched by
pointed or sharp objects, e.g. pens.
Only touch the touch display with
your fingertips.
Touching the display with your finger
creates a tiny charge which releases an
electrical impulse. This impulse is
recognised by the touch display.
The touch display does not react to
contact with objects.
It is possible for the touch display to
fail to react to finger contact if your
fingers are cold.
The touch display is divided into three
sections:
The top row shows you where you are
in a menu. The time of day is shown on
the right-hand side.
The middle row shows the current
menu and options. The most popular
drinks are depicted with symbols in the
Drinksmenu. See "Symbols in the
display" for an explanation of the
symbols.
You can scroll to the right or left using
the and arrows at the bottom.
Context-dependent functions and
menus can be found to the left and right
of the arrow sensors.
