Sensitive surfaces and components
The device can be damaged if it is not appropriately cleaned.
Possible consequences:
ƒ The housing or the screen gets scratched or dull if you use alcoholic,
solvent−containing or scouring cleaning agents.
ƒ Electrical components can be damaged ...
– by a short circuit caused by humidity.
– by static discharge.
Protective measures:
ƒ Observe the following notes.
ƒ Before cleaning, disconnect the device from the power supply as otherwise
unintentional commands may be activated via the touchscreen, for example a
response of the control.
ƒ Clean the device front (screen and frame) as follows:
– Use a clean, lint−free and soft cloth.
– Moisten the cloth with the detergent. Do not spray the detergent directly on the
device.
– Only use water with a fluid addition as detergent or a detergent declared
especially for flat screens.
ƒ Clean the rear side of the device with a clean, lint−free and soft cloth. Do not use
liquid or foaming detergent since it may enter the housing or terminals.
