13 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. A screen cleaning
solution such as an anti-static foam, water with a mild detergent or alcohol should be used
to dampen the cloth. The cleaning solution should be sprayed onto the cloth and not directly
on the terminal. The cleaning solution should not be allowed to reach the terminal electron-
ics, 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 comes in contact with toxic or erosive chemicals, carefully clean the terminal
immediately 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.
