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.

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 indicator and on-screen display icon are illuminated or fl\
ash, 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 ca\
ge 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 t\
he 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 oper\
ation.
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-
XGC55X//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
