Operation
When you touch a button on the touch-
screen, the button in question is briefly
shown outlined in red to confirm the se-
lection.
If you touch a button that is not active at
the moment, a short signal tone sounds.
Calibration
If the touch screen starts responding im-
precisely and e.g. buttons have to
be touched off-centre in order to be actu-
ated, calibration should be undertaken.
The calibration function is started from
