For your own protection and prolonged operation of your LCD 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 LCD Projector, observe the following basic rules for its installation, use and servicing.

17. Unplug the LCD 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 LCD Projector.
c. If the LCD Projector has been exposed to rain or

water.

d. If the LCD Projector does not operate normally

when you follow the operating instructions. Adjust
only those controls that are covered by the oper-
ating instructions, as improper adjustment of other
controls may cause damage and will often require
extensive work by a qualified technician to restore
the LCD Projector to normal operation.

e. If the LCD Projector has been dropped or the

cabinet has been damaged.

f.

When the LCD 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 LCD 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 LCD 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 LCD

Projector manufacturer, as they may cause hazards.

4. Do not use the LCD 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 LCD Projector on an unstable cart, stand,

or table. The LCD 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. LCD 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 LCD 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 LCD Projector should never be placed near or over

a radiator or heating vent. The LCD Projector should not
be placed in a built-in installation such as a bookcase
unless proper ventilation is provided.

10. The LCD 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 LCD Projector
dealer or local power company.

11. Do not place the LCD Projector where the cord will be

abused by persons walking on it.

12. Follow all warnings and instructions marked on the LCD

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 LCD 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 LCD Projector yourself.

Opening or removing covers may expose you to dan-
gerous voltage or other hazards. Refer all servicing to
qualified service personnel.

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 must be cleaned more often. 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 exhaust vent, 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 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.

Potential hazard of glass particles if lamp ruptures. In
case of lamp rupture, contact your nearest Authorised
LCD Projector Dealer or Service Centre for a
replacement.
