Safety instructions and additional information

2.6 Operating the capacitive single-touch screen

2.6 Operating the capacitive single-touch screen
The capacitive touch screen of the HMI device differs fundamentally in its behavior from a
resistive touch screen, for example:
● The touch screen reacts to contact on its surface, not to pressure.
● The touch screen is operated with the fingertips.
● The touch screen is optimized for robust touching, even with a light film of moisture.
● Operation with a touch pen is not recommended.
NOTICE
Damage to the touch screen
The glass surface of the touch screen is sensitive to touch. Improper operation might
damage the touch screen.
• Never touch the touch screen with pointed or sharp objects.
• Do not operate the touch screen with tools, for example a screwdriver.
• Do not operate the touch screen with chain gloves.
Avoid sudden contacts of the touch screen with hard objects. This can substantially reduce
the useful life of the touch screen and even lead to total failure.
