Safety notes
Danger
Risk of electric shock!
Faulty installation of electrical equipment or
mains voltage which is too high can cause electric
shocks.
• Use only the supplied mains adapter.
Make sure that the mains voltage is
correct. More detailed information is
available directly on the mains adapter.
• The switch in the volume control does
not disconnect the unit from the power supply. For this reason, connect it
to an easily accessible socket so that
you can quickly disconnect it from the
power supply in the event of faults.
• Immediately disconnect the mains
adapter from the socket if its casing is
defective or exhibits other visible damage.
• Set up the unit so that the mains plug is
easily accessible and no vent slots are
blocked.
• If the unit emits smoke or smells of
burning or other unusual odours, disconnect it immediately from the power
supply and do not operate it.
• Never open the unit’s housing.
Repairs may only be carried out by an
authorised specialist workshop, otherwise any warranty claims are forfeited. Only use parts for repairs which
conform with the original unit specifications. There are electrical and mechanical parts in this unit which are necessary
in order to avoid exposure to sources of
danger.
• Use only accessories specified by the
manufacturer.
• Do not insert any objects through the
vent slots in the housing.
• Only use the unit in indoor areas, do
not use it in moist areas and protect it
from drops of water or splash water.
Also take care not to stand vases or
other containers filled with liquid on
or near the speaker in order to avoid
liquid getting into the case. If water or
other
foreign bodies should enter the
unit, immediately disconnect the mains
adapter. Then send the unit to our service address.
• Never touch the mains adapter with
wet hands.
• Check the unit regularly for damage.

in the packing film when play-
ing and suffocate.
• Do not allow children to play with the
unit or the packing film. Danger of
suffocation.
• Ensure that children do not remove
small parts from the unit or take them
off of the unit (e.g. control knobs or
the like).They could swallow the parts
and choke. Never allow children to
operate electrical units unsupervised.
Danger to hearing
Extended listening at high volumes may lead to hearing loss.
• To avoid damage to health, avoid extended listening at high volumes.
• When the volume is set high, always
keep a certain distance from the unit
and never place your ear directly on
the speaker.
• Particularly when the subwoofer has
been set to maximum volume and
the unit is activated, very high noise
pressure may suddenly be produced.
This may have psychological consequences and also cause physical injury. Children and pets are particularly at risk. Set your signal source unit
volume control to a low setting before
turning on the power.
Danger
Danger of injury/damage!
Selecting an unsuitable loca-
tion may result in damages.
• Never use the unit unmounted in vehicles, in unstable locations, on wobbly stands or furniture, on underdimensioned brackets etc. The speakers
could tip or fall down and cause injury to persons or be damaged.
• Place the speakers in such a way that
they cannot be knocked over unseen
and make sure that the cables do not
pose a trip hazard.
• Do not place open flames such as
burning candles or similar on the
speakers.
• Do not place the speakers near sources of heat (e.g. heaters, ovens, other heat generating equipment such as
amplifiers etc.).
Attention
Risk of damage!

stroy the unit.
• If the unit is to be left unsupervised
for a long period (e.g. during a holiday), or if a thunderstorm is forecast,
