3.3 user responsibility

3.3.1 Mains connection grounding

Your amplifier must be connected to a
grounded socket outlet.

3.3.2 Speaker output hazard

Power amplifiers are capable of producing
hazardous output voltages. To avoid electrical
shock, do not touch any exposed speaker wiring
while the amplifier is operating. The external wiring
connected to the speaker terminals shall be installed
by a qualified instructed person or ready-made leads
or cords of appropriate capacity shall be used.
As the amplifier outputs produce high voltage,do
not connect or disconnect speaker cables when
the mains power is on. Also, attach the safety cover
on the speaker terminals for safe operation and to
comply with electrical product approvals.

3.3.3 Radio interference

A sample of this product has been tested and complies
with the limits for the European Electro Magnetic
Compatibility (EMC) directive. This equipment has
also been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference
from electrical equipment. This product uses radio
frequency energy and if not used or installed in
accordance with these operating instructions, may
cause interference to other equipment, such as radio
receivers. However, there is no guarantee that inter-
ference will not occur in a particular installation.
If this equipment does cause harmful interference
to radio or television reception, which can be deter-
mined by turning the equipment on and off, the user
is encouraged to try to correct the interference by
one or more of the following measures:
▸ Reorient or relocate the antenna.
▸ Increase the separation between the equipment
and receiver.
▸
Connect the equipment to an outlet on a circuit
different from that to which the receiver is
connected.
▸ Check if the affected unit complies with the EMC limits
for immunity, (CE-labeled). If not, address the problem
with the manufacturer or supplier. All electrical products
sold in the EC must be approved for immunity against
electromagnetic fields, high voltage flashes, and radio inter-
ference.
▸ Consult the dealer or an experienced Radio/TV
technician for help.

3.3.4 Speaker damage

Your amplifier is very powerful and can be
potentially dangerous to bothloudspeakers and
humans alike. Many loudspeakers can be easily
damaged or destroyed by overpowering them. Always
check the speaker's continuous and peak power
capabilities. Although the amplifier's attenuators can
be used to reduce the overall gain,an increase of the
input signal can result in full output power, which
may cause damage to connected speakers.

3.3.5 Maintenance

For safe and reliable operation, the dust covers behind
the front panel should be cleaned regularly. If the dust
filters are not maintained there will be safety risks.
For example the unit can ignite the dust and a fire
will occur due to high internal temperatures. There
is also a risk that the unit will malfunction since it is
dependent on constant airflow from front to rear. If
the dust filters are not clean and the unit malfunc-
tions, any resultant problems will not be covered by
the warranty.
