14 Maintenance
During maintenance as well as servicing, the safety instructions from chapter
2 must be observed.
14.1 Cleaning the Touch Screen
CAUTION
Before cleaning the touch screen, the ETT must be turned off in order to
prevent triggering functions or commands unintentionally!
The touch screen can only be cleaned with a soft, damp cloth. To dampen the cloth, we
recommend a mild cleaning solution such as antistatic foam cleaner. To avoid fluids/cleaning
solutions from getting into the housing, the device must not be sprayed directly. To clean, no
erosive cleaning solutions, chemicals, abrasive cleansers or hard objects that can scratch or
damage the touch screen may be used. The use of steam jets or compressed air is prohibited.
WARNING
If the device is contaminated with toxic or erosive chemicals, it must be
carefully cleaned as quickly as possible to prevent personal injury and
machine damage!
To ensure the optimal function of the panel, the touch screen should be
cleaned in regular intervals!
