3.3 User Responsibility

3.3.1 Mains connection grounding

Your PLM must be connected to a grounded
socket outlet.

3.3.2 Speaker output hazard

PLMs are capable of producing hazardous
output voltages. to avoid electrical shock, do
not touch any exposed speaker wiring while the PLM
is operating. the external wiring connected to the
speaker terminals shall be installed by a trained and
qualified person, or ready-made leads or cords of
appropriate capacity shall be used.
as the power outputs produce high voltage, do
not connect or disconnect speaker cables when
the mains power is on.

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.
4 PLM Series Quick Start and Field Reference
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 electromag-
netic 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 PLM Series device is very powerful and
can be potentially dangerous to both loudspeak-
ers and humans alike. Many loudspeakers can be eas-
ily damaged or destroyed by overpowering them.
always check the speaker's continuous and peak
power capabilities. although the PLM's attenuators
can be used to reduce the overall gain, an increase
of the input signal can result in full channel output
power, which may cause damage to connected
speakers.
3.3.5

Maintenance

For safe and reliable operation, the dust filters 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
malfunctions, any resultant problems will not be
covered by the warranty.
