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.
• Only use the enclosed mains adapter.
When connecting, make sure that the
right voltage is present. 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 pull the mains adapter
out of the socket if the casing is defec-
tive or exhibits other visible damages.
• 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 housing.
Repairs may only be carried out by an
authorised specialist workshop, other-
wise any warranty claims are forfeit-
ed. Only use parts which conform with
the original unit specifi cations. There
are electrical and mechanical parts in
this unit which are essential in order to
avoid exposure to sources of danger.
• Only use accessory products, which
are exclusively specifi ed by the manu-
facturer.
• Do not insert any objects through the
vent slots into 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 fi lled with liquid on
or near the unit in order to avoid liq-
uid getting into the housing. If water
or other foreign bodies should enter
the unit, disconnect it immediately from
the mains power supply. Send the unit
to our service address in this case.
• Never touch the mains adapter with
wet hands.
