CAUTION 

There is potential glass particles hazard if the lamp ruptures.

Some IC chips in this product include confidential and/or trade secret property belonging to Texas Instruments.
Therefore you may not copy, modify, adapt, translate, distribute, reverse engineer, reverse assemble or discompile
the contents thereof.

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.

PRECAUCIÓN

PRÉCAUTION

BQC-XVZ90+++1

There is a potential hazard of glass particles if the lamp ruptures. In case of
lamp rupture, contact your nearest Sharp Authorised Projector Dealer or
Service Centre for a replacement.
See “Replacing the Lamp” on page 46.

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
part of filter must be cleaned more often than usual. 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 a Sharp Authorised Projector Dealer or Service Centre.
• Do not expose the projector to extreme heat or cold.

Operating temperature: +5°C to +35°C
Storage temperature: –20°C to +60°C

• The exhaust ventilative hole, the lamp cage cover and adjacent areas may

get extremely hot during projector operation. To prevent injury, do not touch
these areas until they have sufficiently cooled down.

• Allow at least 30 cm of space between the exhaust ventilative hole 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.

This caution is found at the bottom of the projector. See “Caution Concerning the Lamp Replacement”
on page 2 for its location.

CAUTION 

High brightness light source. Do not stare into the beam of light, or view directly. Be especially careful that
children do not stare directly into the beam of light.

If the projector starts to overheat due to setup problems, “TEMP.” and “

”

will blink 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 blink, and after a 90-second cooling-off period the power will
shut off. Refer to “Lamp/Maintenance Indicators” on page 44 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.

When the projector is turned on after the lamp has been used for 2,400 hours,
“LAMP” and “

” will blink in the lower-left corner of the picture to advise you

to replace the lamp. See page 46 for lamp replacement. If the lamp has been
used for 2,500 hours, the projector power will automatically turn off and the
projector will enter standby mode. Refer to “Lamp/Maintenance Indicators”
on page 44 for details.
