10. Ventilation
Slots and openings in the cabinet are provided for
ventilation to ensure reliable operation of the product and
to protect it from overheating. The openings should never
be covered or blocked by placing the product on a bed,
sofa, rug, or other similar surface. This product should

12. Grounding or Polarization
This product is equipped with a three-wire grounding-type
plug, a plug having a third (grounding) pin. This plug will
only fit into a grounding-type power outlet. This is a safety
feature. If you are unable to insert the plug into the outlet,
contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the grounding-type
plug.13. 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.
14. Lightning

operation.
e. If the product has been dropped or damaged in any
way.
f. If the product exhibits a distinct change in
performance, this indicates a need for service.
19. Replacement Parts

Information
Usage Guidelines
The laser pointer on the remote control emits a laser beam from the laser
pointer window. This is a Class II laser which may impair your sight if directed
into the eyes. The three marks shown on the left are caution labels for the
laser beam.
• Do not look into the laser pointer window or shine the laser beam on yourself or
others. (The laser beam used in this product is harmless when directed onto
the skin. However, be careful not to project the beam directly into the eyes.)
• Always use the laser pointer at temperatures between 41°F and 95°F (
5°C
and 
35°C).
• Use of controls or adjustments, or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Cautions Concerning the Laser Pointer
Cautions Concerning the Setup of the Projector
For minimal servicing and to maintain high image quality, SHARP recommends
that this projector be installed in an area free from humidity, dust and cigarette
smoke. When the projector is subjected to these environments, the lens and
filter must be cleaned more often. Periodically the filter should be replaced
and the projector should be cleaned internally. As long as the projector is
properly maintained in this manner, use in these environments will not reduce
the overall operation life. Please note that all internal cleaning must be
performed by an Authorized Sharp Industrial LCD Products Dealer or Service
Center.

Temperature Monitor Function
If the projector starts to overheat due to setup problems or a dirty air filter, “TEMP.”
and “” will flash in the lower-left corner of the picture. If the temperature continues
to rise, the lamp will turn off, the TEMPERATURE WARNING indicator on the
projector will flash, and after a 90-second cooling-off period the power will shut
off. Refer to “Lamp/Maintenance Indicators” on page 47, for details.
•The cooling fan regulates the internal temperature, and its performance is
automatically controlled. The sound of the fan may change during projector
operation due to changes in the fan speed.
Notes on Operation
•The two marks shown on the left are caution labels for parts of the projector
that emit intense heat during operation.
•The exhaust vents, the lamp cage cover and adjacent areas may be extremely
hot during projector operation. To prevent injury, do not touch these areas until
they have sufficiently cooled.
•Allow at least 4 inches (10 cm) of space between the cooling fan (exhaust
vent) and the nearest wall or obstruction.
•If the cooling fan becomes obstructed, a protection device will automatically
turn off the projector lamp. This does not indicate a malfunction. Remove the
projector power cord from the wall outlet and wait at least 10 minutes. Then
turn on the power by plugging the power cord back in. This will return the
projector to the normal operating condition.
