Cleaning the lens
■ Use a commercially available blower or lens clean-
ing paper (for glasses and camera lenses) for clean-
ing the lens. Do not use any liquid type cleaning
agents, as they may wear off the coating film on the
surface of the lens.
■ As the surface of the lens can easily get damaged,
ensure not to scrape or hit the lens.
Cleaning the exhaust and intake vents
■ Use a vacuum cleaner to clean dust from the ex-
haust vent and the intake vent.
Info
• If you want to clean the air vents during projec-
tor operation, ensure to press 
 on the pro-
jector or 
 on the remote control and put the
projector into standby mode. After the cooling
fan has stopped, unplug the power cord from
the AC socket and clean the vents.
Cleaning the projector
■ Ensure the power cord is unplugged before cleaning
the projector.
■ The cabinet as well as the operation panel is made
of plastic. Avoid using benzene or thinner, as these
can damage the finish on the cabinet.
■ Do not use volatile agents such as insecticides on
the projector.
Do not attach rubber or plastic items to the projec-
tor for long periods.
The effects of some of the agents in the plastic may
cause damage to the quality or finish of the projector.
■ Wipe off dirt gently with a soft flannel cloth.
■ When the dirt is hard to remove, soak a cloth in a
mild detergent diluted with water, wring the cloth
well and then wipe the projector.
Strong cleaning detergents may discolor, warp or
damage the coating on the projector. Make sure to
test on a small, inconspicuous area on the projec-
tor before use.

Hg LAMP CONTAINS MERCURY For State Lamp Disposal Information
www.lamprecycle.org or 1-800-BE-SHARP
Caution Concerning the Lamp
■ This projector utilizes a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp
failure can be attributed to numerous sources such as: excessive shock, improper cooling, surface
scratches or deterioration of the lamp due to a lapse of usage time.
The period of time up to failure largely varies depending on the individual lamp and/or the condition
and the frequency of use. It is important to note that failure can often result in the bulb cracking.
■ When the lamp replacement indicator and on-screen display icon are illuminated, it is recommended
that the lamp be replaced with a new one immediately, even if the lamp appears to be operating
normally.
■ Should the lamp break, the glass particles may spread inside the lamp cage or gas contained in the
lamp may be vented into the room from the exhaust vent. Because the gas in this lamp includes
mercury, ventilate the room well if the lamp breaks and avoid all exposure to the released gas. In
case of exposure to the gas, consult a doctor as soon as possible.
■ Should the lamp break, there is also a possibility that glass particles may spread inside of the
projector. In such a case, it is recommended you contact your nearest Sharp Authorized Projector
Dealer or Service Center to assure safe operation.
Replacing the Lamp
Caution
• Do not remove the lamp unit from the projector right after use. The lamp will be very hot and may cause burn
or injury.
• Wait at least one hour after the power cord is disconnected to allow the surface of the lamp unit to fully cool
before removing the lamp unit.
■ Carefully change the lamp by following the instructions described in this section. *If you wish, you
may have the lamp replaced at your nearest Sharp Authorized Projector Dealer or Service Center.
* If the new lamp does not illuminate after replacement, take your projector to the nearest Sharp Authorized
Projector Dealer or Service Center for repair.
