Cleaning the Touch Screen
CAUTION!
Before cleaning the touch screen, the terminal must first be turned off to avoid unin-
tentionally triggering functions or commands!
The terminal's touch screen can only be cleaned with a soft, damp cloth. To dampen the
cloth, a screen-cleaning solution such as an antistatic foam, water with detergent or alcohol
should be used. First spray the cleaning fluid on the cloth and not directly on the terminal.
The cleaning solution should not be allowed to reach the terminal electronics, for example,
through the ventilation slots.
No erosive cleaning solutions, chemicals, abrasive cleansers or hard objects that can
scratch or damage the touch screen may be used.
If the terminal is soiled with toxic or acidic chemicals, quickly and carefully clean the termi-
nal to prevent corrosion.
To ensure the optimal function of the terminal, the touch screen should be cleaned
at regular intervals!
To extend the lifespan of the touch screen as much as possible, using the fingers to
operate the terminal is recommended.
