Operating Touch Elements

Operating concept
The screen is used to observe the operating status of the machine or system being
monitored and, at the same time, to intervene directly in the process running
simply by touching the buttons and input fields displayed.
Definition
Touch elements are contact–sensitive operating elements provided on the touch
panel screen, such as buttons and input fields. Their operation is basically no
different from pressing conventional keys. Touch elements are operated by
touching them lightly with your finger or a suitable object.
Note
Never use pointed or sharp instruments to operate the Touch Panel to prevent
damage to the plastic surface of the touch screen.
Caution
!
Never touch more than one touch panel screen element at a time. If you do, an
unintended action may be initiated.
