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 elec‐
trical impulse. This impulse is recognised by the touch display. The touch display
does not react if you touch it with an object.
If your fingers are cold, the Touch display may not react.
The touch display is divided into three sections:
The top row shows you where you are, with the menu you are in highlighted in
white. Open the menu you want by touching the menu name. The time of day is
shown in the top right-hand corner.
The middle row shows the current menu and options. You can scroll to the right or
left by swiping your finger across the display to the right or left.
The and arrow sensors at the bottom of the screen are used for scrolling to
the left or right.
The number of small squares between the arrows indicates the number of pages
available and your position within the current menu.
