Cleaning And Maintenance
NOTICE
External influences may damage or de-
stroy the device.
– If the device is to be left unattended for
a prolonged period of time (e.g. during a
vacation) or if a thunderstorm is forecast,
pull the wall adapter out of the socket.
Otherwise, sudden overvoltage could
cause the device to become defective.
– If possible, only use plain water without
any additives. In case of stubborn marks,
a mild soap solution may be used.
– Do not use caustic cleaning products,
white spirit, thinners, petrol or similar
under any circumstances. Such cleaning
agents may damage the delicate surface
of the housing.

• Ideally, you should remove dust or small amounts
of dirt with a dry, smooth leather cloth.
• Use a damp cloth to rub off stubborn dirt. Make
sure that no liquid penetrates the housing.
• Then immediately wipe the damp surfaces off with
a soft cloth without applying pressure.
