Safety Instructions
Caution!
Keep this device away from rain and moisture!
Caution!
Be careful with your operations. With a dangerous
voltage you can suffer a dangerous electric shock
when touching the wires!
Health hazard!
By operating an amplifying system, you can produce
excessive sound pressure levels that may lead to
permanent hearing loss.
This device has left our premises in absolutely
perfect condition. In order to maintain this
condition and to ensure a safe operation, it is
absolutely necessary for the user to follow the
safety instructions and warning notes written in this
user manual.
Damages caused by the disregard of this user
manual are not subject to warranty. The dealer will
not accept liability for any resulting defects or
problems.
Unpacking
•
Please make sure that there are no obvious transport
damages. Should you notice any damages on the
connection panel or on the casing, do not take the
speaker system into operation and immediately
consult your local dealer.
•
Keep the packaging. To fully protect the device
against
vibration, dust and moisture during
transportation or storage use the original packaging.
Protection Class
•
This device falls under protection class I. The power
plug must only be plugged into a protection class I
outlet. The voltage and frequency must exactly be the
same as stated on the device. Wrong voltages or
power outlets can lead to the destruction of the device
and to mortal electrical shock.
Power Cord
•
Always plug in the power plug least. The power plug
must always be inserted without force. Make sure that
the plug is tightly connected with the outlet.
•
Never let the power cord come into contact with other
cables! Handle the power cord and all connections
with the mains with particular caution! Never touch
them with wet hands, as this could lead to mortal
electrical shock.
•
Never modify, bend, strain mechanically, put pressure
on, pull or heat up the power cord. Never operate next
to sources of heat or cold. Disregard can lead to
power cord damages, fire or mortal electrical shock.
•
The cable insert or the female part in the device must
never be strained. There must always be sufficient
cable to the device. Otherwise, the cable may be
damaged which may lead to mortal damage.
•
Make sure that the power cord is never crimped or
damaged by sharp edges. Check the device and the
power cord from time to time.
•
If extension cords are used, make sure that the core
diameter is sufficient for the required power
consumption of the device. All warnings concerning
the power cords are also valid for possible extension
cords.
•
Always disconnect from the mains, when the device is
not in use or before cleaning it. Only handle the power
cord by the plug. Never pull out the plug by tugging
the power cord. Otherwise, the cable or plug can be
damaged leading to mortal electrical shock. If the
power plug or the power switch is not accessible, the
device must be disconnected via the mains.
•
If the power plug or the device is dusty, the device
must be taken out of operation, disconnected and
then be cleaned with a dry cloth. Dust can reduce the
insulation which may lead to mortal electrical shock.
More severe dirt in and at the device should only be
removed by a specialist.
Liquids
•
There must never enter any liquid into power outlets,
extension cords or any holes in the housing of the
device. If you suppose that also a minimal amount of
liquid may have entered the device, it must
immediately be disconnected. This is also valid, if the
device was exposed to high humidity. Also if the
device is still running, the device must be checked by
a specialist if the liquid has reduced any insulation.
Reduced insulation can cause mortal electrical shock.
Foreign Objects
• There must never be any objects entering into the
device. This is especially valid for metal parts. If any
metal parts like staples or coarse metal chips enter
into the device, the device must be taken out of
operation and disconnected immediately. Malfunction
or short-circuits caused by metal parts may cause
mortal injuries.
Avoiding Hum
•
Never install the amplifier next to highly sensitive
devices like pre-amplifiers or tape-decks, as the
strong magnetic field of the amplifier can produce
hum in these devices. The magnetic field is strongest
directly above or below the amplifier. If a rack is used,
the amplifier should be installed at the bottom and the
highly sensitive devices at the top.
