Maintenance/Upkeep
Cleaning the screen
Clean the operating unit screen at regular intervals using a damp cloth. Before
starting, either switch off the unit or deactivate the screen. The way to deactivate
the screen is described in chapter 6.3. This ensures that functions are not
triggered inadvertently by coming into contact with the screen.
Only use water and washing up liquid or screen cleaning foam to dampen cloths.
Never spray the cleaning agent directly onto the screen, but onto the cleaning
cloth. Never use aggressive solvents or scouring powder.
Protective foil
A protective foil is available for the operating unit (refer to the ST80 catalog). The
foil prevents the screen being scratched and soiled.
