INFORMATION TO THE USER
NOTE : This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
TO THE OWNER
As the owner of a new Multi-media Projector, you are probably eager to try out your new projector. Before you do, we suggest
that you spend a little time reading this manual to familiarize yourself with the operating procedures, so that you will receive
maximum satisfaction from the many features included in your new projector.
This owner’s manual will acquaint you with your projector’s features. Reading it will help us too. Through the years, we have
found that many service requests were not caused by problems with our projectors. They were caused by problems that
could have been prevented, if the owner had followed the instructions in the manual.
You can often correct operating problems yourself. If your projector fails to work properly, see “TROUBLESHOOTING”
section on pages 49 ~ 50 and try the solutions marked for each problem.

IMPORTANT SAFETY INSTRUCTIONS
All the safety and operating instructions should be read
before the product is operated.
Read all of the instructions given here and retain them for
later use. Unplug this projector from AC power supply
before cleaning. Do not use liquid or aerosol cleaners. Use
a damp cloth for cleaning.
Do not use attachments not recommended by the
manufacturer as they may cause hazards.
Do not place this projector on an unstable cart, stand, or
table. The projector may fall, causing serious injury to a
child or adult, and serious damage to the projector. Use
only with a cart or stand recommended by the
manufacturer, or sold with the projector. Wall or shelf
mounting should follow the manufacturer’s instructions,
and should use a mounting kit approved by the
manufacturer.
Do not expose this unit to rain or use near water... for
example, in a wet basement, near a swimming pool, etc...
Slots and openings in the back and bottom of the cabinet
are provided for ventilation, to insure reliable operation of
the equipment and to protect it from overheating.
The openings should never be covered with cloth or other
material, and the bottom opening should not be blocked by
placing the projector on a bed, sofa, rug, or other similar
surface. This projector should never be placed near or
over a radiator or heat register.
This projector should not be placed in a built-in installation
such as a bookcase unless proper ventilation is provided.
This projector 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 supplied, consult your authorized
dealer or local power company.
Do not overload wall outlets and extension cords as this
can result in fire or electric shock. Do not allow anything to
rest on the power cord. Do not locate this projector where
the cord may be damaged by persons walking on it.
Never push objects of any kind into this projector through
cabinet slots as they may touch dangerous voltage points
or short out parts that could result in a fire or electric
shock. Never spill liquid of any kind on the projector.
Do not attempt to service this projector yourself as opening
or removing covers may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service
personnel.
Unplug this projector from wall outlet and refer servicing to
qualified service personnel under the following conditions:
a. When the power cord or plug is damaged or frayed.
b. If liquid has been spilled into the projector.
c. If the projector has been exposed to rain or water.
d. If the projector does not operate normally by following the
operating instructions. Adjust only those controls that are
covered by the operating instructions as improper
adjustment of other controls may result in damage and
will often require extensive work by a qualified technician
to restore the projector to normal operation.
e. If the projector has been dropped or the cabinet has been
damaged.
f. When the projector exhibits a distinct change in
performance-this indicates a need for service.
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
original part. Unauthorized substitutions may result in fire,
electric shock, or injury to persons.
Upon completion of any service or repairs to this projector,
ask the service technician to perform routine safety checks
to determine that the projector is in safe operating condition.
This projector is equipped with a
grounding type AC line plug. Should
you be unable to insert the plug into
the outlet, contact your electrician.

this grounding type plug.
GROUND
Follow all warnings and instructions marked on the
projectors.
For added protection to the projector during a lightning
storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet. This will
prevent damage due to lightning and powerline surges.
An appliance and cart combination
should be moved with care. Quick
stops, excessive force, and uneven
surfaces may cause the appliance
and cart combination to overturn.
If the projector is to be built into a compartment or similarly
enclosed, the minimum distances must be maintained.
Do not cover the ventilation slot on the projector.
Heat build-up can reduce the service life of your projector,
and can also be dangerous.
