Important

Information

Temperature Monitor Function

If the projector starts to overheat due to setup problems or a dirty air filter, “TEMP.”

will appear 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 39, 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.

Lamp Monitor Function

When the projector is turned on after the lamp has been used for 900 hours,

“LAMP” will appear in the lower-left corner of the picture to advise you to replace

the lamp. See pages 40 and 41 for lamp replacement. If the lamp has been used

for 1,000 hours, the projector power will automatically turn off and the projector

will enter standby mode. Refer to “Lamp/Maintenance Indicators” on page 39,

for details.

Usage Guidelines

Caution Concerning the Lamp Unit

Potential hazard of glass particles if lamp ruptures. Please have Authorized Sharp

Industrial LCD Products Dealer or Service Center replace lamp if rupture occurs.

See “Replacing the Projection Lamp” on pages 40 and 41.

Cautions Concerning the Setup of the Projector

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

filter must be cleaned more often. Periodically the filter should be replaced and

the projector should be cleaned internally. 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 an

Authorized Sharp Industrial LCD Products Dealer or Service Center.

• Do not expose the projector to extreme heat or cold.

Operating temperature: 41°F to 95°F (Ⳮ5°C to Ⳮ35°C)

Storage temperature: ⳮ4°F to 140°F (ⳮ20°C to Ⳮ60°C)

• The mark shown on the left calls the user’s attention to a part of the projector

that emits intense heat during operation.

• 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 4 inches (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.
