The touch screen calibration is normally not needed in a reasonable use of the screen
and in standard environmental conditions.
To prevent loss of the touch screen interface, the possibility is meanwhile given to the
user to manually calibrate the XY coordinates necessary to detect button activation.
Warning: Touch screen calibration has to be done carefully with a pen or a stylus in
order to accurately mark and detect the calibration points!
The backlight adjustment menu set the default backlight intensity when the touch
screen is used. After 10 minutes of touch screen inactivity, the backlight intensity returns
to 10%.
