Danger
Risk of electric shock!
Faulty installation of electrical equipment or
mains voltage which is too high can cause
electric shocks.
• The unit is only suitable for use with a power supply
voltage of 230 V~/50 Hz. Make sure that the mains
voltage is correct. For more information, refer to the
nameplate.
• Check the unit regularly for damage.
If the unit’s case or mains cable is defective or shows
other signs of visible damage, disconnect the mains
adapter immediately from the socket and do not oper-
ate the unit.
• The standby button does not disconnect the unit from
the power supply. For this reason, connect it to an eas-
ily accessible socket so that you can quickly disconnect
it from the power supply in the event of faults.
• 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 housing.
Repairs may only be carried out by an authorised spe-
cialist workshop. In the process, only parts may be used,
which correspond to the original unit data. There are
electrical and mechanical parts in this unit which are es-
sential in order to avoid exposure to sources of danger.
• Do not insert any object through the vent slots in the
housing.
• Only use the unit in indoor areas.
• Do not operate the unit in moist areas and protect it
from drops of water or splash water.
Ensure that no vases or other vessels containing
liquids are on the unit or in its vicinity so that no liquid
penetrates the housing. Should water or any other
foreign object penetrate the unit, immediately disconnect
the mains plug and, if applicable, remove any batteries
present. Then send the unit to our service address.
• Never touch the mains plug with wet hands.

pervised.

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 maxi-
mum 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 chemical burns!
Leaking battery acid may lead to chemical
burns.
• Do not allow battery acid to come into contact with
skin, eyes or mucus membranes. In case of contact
with acid rinse the affected locations immediately with
plenty of plain water and (if necessary) see a doctor.
Danger

• Never use the unit unmounted in vehicles, in instable
locations, on wobbly stands or furniture, with attach-
ment fixtures that are too small etc. The unit could
topple over or fall, injuring persons or causing damage
to the unit itself.
• Set up the speakers so that there is no risk of them
tipping over and the cables don’t represent a tripping
hazard.
• Ensure that any wall mounting is performed in a profes-
sional manner.
• Only use suitable wall brackets for mounting. Check
the carrying capacity of the walls.
• Do not place the unit near sources of heat (e.g. heat-
ers, ovens, other heat generating equipment such as
amplifiers etc.).
