For your own protection and prolonged operation of your projector, be sure to read the following “Important
Safeguards” carefully, before use.
This projector has been engineered and manufactured to ensure your personal safety. But IMPROPER USE CAN
RESULT IN POTENTIAL ELECTRICAL SHOCK OR FIRE HAZARDS. In order not to defeat the safeguards
incorporated into this projector, observe the following basic rules for its installation, use and servicing.

17. Unplug the projector equipment from the 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 when

you follow the operating instructions. Adjust only
those controls that are covered by the operating
instructions, as improper adjustment of other
controls may cause 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.

18. When replacement parts are required, be sure the ser-

vice technician has used replacement parts specified by
the manufacturer that have the same characteristics as
the original parts. Unauthorised substitutions may result
in fire, electric shock, or other hazards.

19. This projector is provided with one of the following types

of plugs. If the plug should fail to fit into the power outlet,
please contact your electrician.
Do not defeat the safety purpose of the plug.

a. Two-wire type mains plug.

b. Three-wire grounding type mains plug with a

grounding terminal.
This plug will only fit into a grounding type power
outlet.

1. Unplug the projector from the wall outlet before

cleaning.

2. Do not use liquid cleaners or aerosol cleaners. Use a

damp cloth for cleaning.

3. Do not use attachments not recommended by the

projector manufacturer, as they may cause hazards.

4. Do not use the projector near water; for example, near a

bathtub, washbowl, kitchen sink, laundry tub, in a wet
basement, near a swimming pool, etc. Never spill liquid
into the projector.

5. 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.

6. Wall or Ceiling Mounting—The product should be

mounted to a wall or ceiling only as recommended by
the manufacturer.

7. 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.

8. Slots and openings in the cabinet back and bottom 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. The openings
should never be covered with cloth or other material.

9. This projector should never 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 provided.

10. The projector should be operated only from the type of

power source indicated on the back of the projector or in
the specifications. If you are not sure of the type of power
supplied to your home, consult your projector dealer or
local power company.

11. Do not place the projector where the cord will be abused

by persons walking on it.

12. Follow all warnings and instructions marked on the

projector.

13. To prevent damage to the projector due to lightning and

power-line surges, unplug the projector from the power
outlet, when not in use.

14. Do not overload wall outlets and extension cords with too

many products, because this can result in fire or electric
shock.

15. Never push objects of any kind into the projector through

the cabinet slots as they may touch high-voltage points
or cause a short circuit. This could result in a fire or electric
shock.

16. Do not attempt to service the projector yourself. Opening

or removing covers may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service
personnel.

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 two 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 

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.

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. If the projector is used in these environments, the lens and filter will
need to be cleaned (or the filter replaced) more often, and internal cleaning
may become necessary. As long as the projector is regularly cleaned, use in
these environments will not reduce the overall operation life of the unit. Internal
cleaning should only be performed by a Sharp Authorised LCD Projector
Dealer or Service Centre.

• 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 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.

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.
