bathtub, washbowl, kitchen sink, or laundry tub, in a wet
basement, near a swimming pool, etc. Never spill liquid into
the projector.
Do not place the projector on an unstable cart, stand, or
table. The projector may fall, which may cause serious injury
to a child or an adult and/or serious damage to the unit. Use
only with a cart or stand recommended by its manufacturer
as being suitable for use with a projector.
Ceiling, wall or shelf mounting should be done with a
mounting kit approved by the manufacturer for use with a
projector and should follow the manufacturers instructions.
Projector equipment and cart combinations should be moved
with care. Quick stops, excessive force, and uneven surfaces
may cause the equipment and cart combination to overturn.
Slots and openings in the sides and bottom of the cabinet
are provided for ventilation. To ensure reliable operation of
the projector and to protect it from overheating, these
openings must not be blocked or covered. These openings
should never be covered with cloth or other material. The
bottom opening should not be blocked by placing the
projector on a bed, sofa, rug, or other similar surface. The
projector should not be placed near or over a radiator or
heating vent. The projector should not be placed in a built-in
installation such as a bookcase unless proper ventilation is
The projector should be operated only from the type of
power source indicated on the side of the projector or in the
specifications and with the appropriate mains lead. If you are
not sure of the type of power supplied to your business or
the right type of mains lead, consult your projector dealer or
local power company.
Do not allow anything to rest on the power cord. Do not
place the projector where the cord will be walked on.
Follow all warnings and instructions marked on the projector.
As a safety feature, this projector is equipped with mains
lead with a 3-pin grounded plug (for USA-versions only) or a
2-pin grounded plug (for European versions only). The 3-pin/2-
pin grounded plug will fit only into a grounding type power
outlet. If the plug does not fit, use an adapter that is properly
grounded or have an electrician install a grounded type
outlet. Do not attempt to modify this AC plug.
For added protection of the projector during a lightning
storm, or when it is left unattended or not in use for long
periods of time, unplug it from the wall outlet and disconnect
any cable systems. This will prevent damage to the projector
due to lightning and power-line surges.

performance (this indicates a need for service).
Upon completion of any service or repairs to the projector,
ask the service technician to perform a routine safety check
to check that the projector is in safe operating condition.
When replacement parts are required, be sure the service
technician has used replacement parts specified by the
manufacturer that have the same characteristics as the
