■ Potential hazard of glass particles if

lamp ruptures. In case of lamp rupture,
contact your nearest Sharp Authorized
Projector Dealer or Service Center for
a replacement.
See “Replacing the Lamp” on page 

■ For minimal servicing and to maintain high image qual-

ity, 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 environ-
ments will not reduce the overall operation life of the
unit. Internal cleaning should only be performed  by a
Sharp Authorized Projector Dealer or Service Center.

■ Position the screen so that it is not in direct sunlight or

room light. Light falling directly on the screen washes
out the colors, making viewing difficult. Close the cur-
tains and dim the lights when setting up the screen in a
sunny or bright room.

■ Placement should be within ±12 degrees.

■ Take care with the lens so as not to hit or damage the

surface of the lens.

■ Continuously watching the screen for long hours will

make your eyes tired. Be sure to occasionally rest your
eyes.

■ The operating temperature for the projector is from 41°F

to 104°F (+5°C to +40°C).

■ The storage temperature for the projector is from

–4°F to 140°F (–20°C to +60°C).

■ Allow at least 7.9 inches (20 cm) of space between the

exhaust vent and the nearest wall or obstruction.

■ Be sure that the intake vent and the exhaust vent are

not obstructed.

■ If the cooling fan becomes obstructed, a protection cir-

cuit will automatically turn off the projector. This does
not indicate a malfunction. Remove the projector power
cord from the wall outlet and wait at least 10 minutes.
Place the projector where the intake and exhaust vents
are not blocked, plug the power cord back in and turn
on the projector. This will return the projector to the
normal operating condition.

■ When transporting the projector, be sure not to subject

it to hard impact and/or vibration, as this can result in
damage. Take extra caution with the lens. Before mov-
ing the projector, be sure to unplug the power cord from
the wall outlet, and disconnect any other cables con-
nected to it.

■ When connecting a computer or other audio-visual

equipment to the projector, make the connections AF-
TER turning off the projector and the equipment to be
connected.

■ Please read the operation manuals of the projector and

the equipment to be connected for instructions on how
to make the connections.

■ The power supply voltage and the shape of the plug

may vary depending on the region or country you are
using the projector in. When using the projector over-
seas, be sure to use the appropriate power cord for
the country you are in.

■ If the projector starts to overheat

due to setup problems or block-
age of the air vents, “

” 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 in-
dicator on the projector will blink, and after a 90-sec-
ond cooling-off period the power will shut off. Refer to
“Maintenance Indicators” on page 

 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. This does not indicate
malfunction.

• Do not unplug the power cord during projection or cool-

ing fan operation. This can create damage due to the
rise in internal temperature, as the cooling fan also
stops.
