IMPORTANT SAFEGUARDS (cont.)

Be sure to read the following safeguards when setting up

your projector.

Caution concerning the lamp unit

■ Potential hazard of glass particles if

lamp ruptures. In case of lamp rup-

ture, contact your nearest Sharp Au-

thorized Projector Dealer or Service

Center for a replacement.

See “Replacing the Lamp” on page 71.

Cautions concerning the setup of the projector

■ 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.

Do not set up the projector in places exposed to

direct sunlight or bright light.

■ 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.

Tilt the projector so that it does not go over an

angle of 10 degrees when setting it.

■ The placement range (the

horizontal angle) should

be within ±10 degrees.

Do not subject the projector to hard impact and/

or vibration.

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

surface of the lens.

Rest your eyes occasionally.

■ Continuously watching the screen for long hours will

make your eyes tired. Be sure to occasionally rest your

eyes.

Avoid locations with high or low temperature.

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

to 95°F (+5°C to +35°C)

■ The storage temperature for the projector is from

–4°F to 140°F (–20°C to +60° C)

Do not block the exhaust and intake vents.

■ Allow at least 11.8 inches (30 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 more than 10 min-

utes. 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.

Cautions regarding the transportation of the pro-

jector

■ 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.

Other connected equipment

■ 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.

Using the projector in other Countries

■ 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.

Temperature monitor function

■ 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 WARN-

ING indicator on the projector will blink, and after a 90-

second cooling-off period the power will shut off. Refer

to “Maintenance Indicators” on page 70 for details.

Info

• 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.
