Clean the subwoofer and the satellites regularly with a
soft, damp microfi ber cloth. When doing so, please be
absolutely sure to observe the following instructions:
Danger
Risk of electric shock!
In contact with live parts, water can lead to
electric shock or short circuit.
• Make sure that no liquid penetrates the unit.
• Disconnect the mains plug before cleaning.
Attention
Risk of damage!
Using the wrong cleaning materials may dam-
age the delicate surface of the case.
• If possible use only plain water with no cleaning prod-
ucts. In case of stubborn marks, a mild soap solution
may be used.
• In no circumstances should caustic cleaning products,
white spirit, thinners, petrol or similar be used for
cleaning.
Disposing of the unit
Used units must not be disposed of with house-
hold waste.
If the unit is no longer operational, every
consumer is required by law to dispose of
used devices separate from household waste,
e.g. at a collection point run by the communal author-
ity/borough. In this way, used devices can be recycled
and waste materials disposed of in an environmentally
friendly manner.
For this reason, electrical equipment is labelled with the
displayed symbol.
Protecting the environment
Batteries and rechargeable batteries

they contain harmful substances*) or not, to a collection
point run by the communal authority or borough or run
commercially, so that they can be disposed of in an envi-
ronmentally friendly manner.
Please only hand in fully discharged batteries and stor-
age batteries!
