Cleaning the lens
■Use a commercially available blower or lens
cleaning paper (for glasses and camera lenses)
for cleaning the lens. Do not use any liquid type
cleaning agents, as they may wear off the coat-
ing film on the surface of the lens.
■As the surface of the lens can easily get dam-
aged, be sure not to scrape or hit the lens.
Cleaning the exhaust and intake vents
■Use a vacuum cleaner to clean dust from the
exhaust vent and the intake vent.
Maintenance
Cleaning the projector
■Be sure to unplug the power cord before clean-
ing 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 on the pro-
jector for long time.
    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
neutral 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 projector before using.

mately 1,500 hours with “OFF” in “Power
Save” (see page 69).
■When the remaining lamp life becomes
6% or less, “

Maintenance Indicators
Info
•If the temperature warning indicator illuminates, and the power turns off, follow the above possible solutions
and then wait until the projector has cooled down completely before plugging in the power cord and  turning
the power back on. (At least 5 minutes.)
•If the power is turned off and then turned on again, as during a brief test, the lamp replacement indicator may
be triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet
and plug it back in again.
•If you want to clean the air vents during projector operation, be sure to first press 
 and after the power has
turned off and the cooling fan has stopped, then clean the vents.
•Do not unplug the power cord after the power has been turned off and while the cooling fan is running. The
cooling fan runs for about 90 seconds.

Lamp
■It is recommended that the lamp (sold separately) be replaced when the remaining lamp life be-
comes 6% or less, or when you notice a significant deterioration in the picture and color quality. The
lamp life (percentage) can be checked with the on-screen display. See page 70.
■For lamp replacement, please consult your nearest Sharp Authorized Projector Dealer or Service
Center.
IMPORTANT NOTE TO U.S. CUSTOMERS:
The lamp included with this projector is backed by a 90-day parts and labor limited warranty. All service
of this projector under warranty, including lamp replacement, must be obtained through a Sharp Autho-
rized Projector Dealer or Service Center. For the name of the nearest Sharp Authorized Projector Dealer
or Service Center, please call toll-free: 1-888-GO-SHARP (1-888-467-4277).
U.S.A. ONLY
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 or flash, it is rec-
ommended 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 with 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 remove the damaged lamp and assure safe operation.
Replacing the Lamp
Caution
•Do not remove the lamp unit immediately after operation of the projector. The lamp will be hot and touching
it can lead to 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.
■If the new lamp does not light after replacement, take your projector to the nearest Sharp Autho-
rized Projector Dealer or Service Center for repair. Purchase a replacement lamp unit of type BQC-
XGC50X//1 from your nearest Sharp Authorized Projector Dealer or Service Center. Then 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.
