Safety notes
Danger
Risk of electric shock!
Faulty installation of electri-
cal equipment or mains volt-
age 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 pow-
er 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 dam-
age.
• 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, dis-
connect 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, other-
wise any warranty claims are forfeit-
ed. Only use parts for repairs which
conform with the original unit specifica-
tions. There are electrical and mechani-
cal 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 serv-
ice address.
• Never touch the mains adapter with
wet hands.
• Check the unit regularly for damage.
