the product and in the operating
instructions should be adhered to.
4. Follow Instructions.

example, near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet
basement or near a swimming pool,
and the like.
6. Accessories. 
Do not place this
product on an unstable cart, stand,
tripod, bracket or table. The product
may fall, causing serious injury to a
child or adult, and serious damage
to the product. Use only with a
cart, stand, tripod, bracket or table
recommended by the manufacturer,
or sold with the product. Any
mounting of the product should 
follow the manufacturer’s instruc-
tions, and should use a mounting
accessory recommended by the 
manufacturer.
7. Wall or Ceiling Mounting. 
The
product should be mounted on a
wall or ceiling only when and as
recommended by the manufacturer.
8. Ventilation. 
Slots and openings
in the cabinet are provided for 
ventilation and to ensure reliable
operation of the product and to 
protect it from overheating, and
these openings must not be blocked
or covered. The openings should
never be blocked by placing the
product on a bed, sofa, rug or other
similar surface. This product should
not be placed in a built-in installa-
tion such as a bookcase or rack
unless proper ventilation is provided
or the manufacturer’s instructions
have been adhered to.
9. Heat.
The product should be 
situated away from heat sources
such as radiators, heat registers,
stoves or other products that 
produce heat. If placed near an
amplifier, check with the 
manufacturer for applicability.
10. Power Sources.
This product
should be operated only from the
type of power source indicated on
the marking label. If you are not
sure of the type of power supply to
your home, consult your product
dealer or local power company. For
products intended to operate from
battery power, or other sources,
refer to the operating instructions.
11. Grounding or Polarization.
This product may be equipped with
a polarized alternating-current line
plug (a plug having one blade wider
than the other). This plug will fit
into the power outlet only one way.
This is a safety feature. If you are
unable to insert the plug fully into
the outlet, try reversing the plug. If
the plug should still fail to fit, con-
tact your electrician to replace your 
obsolete outlet. Do not defeat the
safety purpose of the polarized
plug.
12. Power-Cord Protection.
Power-
supply cords should be routed so
that they are not likely to be
walked on or pinched by items
placed upon or against them, 
paying particular attention to cords
at plugs, convenience receptacles
and the point where they exit from
the product.
13. Cleaning.
Unplug this product
from the wall outlet before clean-
ing. Do not use liquid cleaners or
aerosol cleaners. Use a damp cloth
for cleaning.

The power
cord of the product should be
unplugged from the outlet when
left unused for long periods of time.
15. Lightning.
For added protec-
tion for this product during a light-
ning storm, or when it is left unat-
tended and unused for long periods
of time, unplug it from the wall
outlet and disconnect the antenna
or cable system. This will prevent
damage to the product due to light-
ning and power-line surges.
16. Overloading.
Do not overload
wall outlets, extension cords or
integral convenience receptacles, as
this can result in a risk of fire or
electric shock.
17. Object and Liquid Entry.

Speakers and electronics ter-
minals have corresponding (+)
and (–) terminals. It is impor-
tant to connect both speakers
identically: (+) on the speaker
to (+) on the amplifier and
(–) on the speaker to (–) 
on the amplifier. Wiring “out
