carrying case.
1Open the cover of the carrying
case.
2Remove the inner padding
from the carrying case, and
fold it in the direction of the
arrows.
3Reinsert the inner padding into
the carrying case.
Info
•Be sure to insert the inner padding
to protect the lens and the projector.
4Place the projector and the ac-
cessories in the carrying case.
Info
•Be sure to attach the lens cap to
protect the lens.
•Be sure the projector has cooled
down enough before placing it in the
case.
Info
•This carrying case is only for storing and
carrying the projector.
•Sending the projector in the carrying case
as a parcel may cause damage to the
projector. If you send the projector in the
carrying case as a parcel, be sure to
place it in a sturdy case and with enough
shock absorbing material to avoid any
damage.
•Do not expose the carrying case or pro-
jector to direct sunlight, near heat
sources, or leave them in a car. The car-
rying case or projector may change color
or become deformed.Adjust the

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.
Cleaning
Paper
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.

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 indica- 
tor 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.
About the TEMPERATURE WARNING indicator
If the temperature inside the projector in- 
creases, due to blockage of the air vents, or 
the setting location,  “
” will blink in the
lower left corner of the picture. If the tem- 
perature keeps on rising, the lamp will turn 
off and the TEMPERATURE WARNING in-
dicator will blink, the cooling fan will run for 
further 90 seconds, then the power will be 
shut off. After  “
” appears, be sure to
perform the following measures.


The warning lights on the projector indicate problems inside the projector.

 If a problem occurs, either the TEMPERATURE WARNING indicator or the LAMP REPLACEMENT 
indicator will illuminate red, and the power will turn off. After the power has been turned off, follow
the procedures given below.
About the 
LAMP
REPLACEMENT
indicator

When the lamp
exceeds 1,900 cumulative hours 
of use,  “
” will be displayed
on the screen in yellow. When 
the cumulative hours of use 
reach 2,000,  “
” will
change to red, the lamp will au- 
tomatically turn off and then the 
projector as well. At this time, the 
LAMP REPLACEMENT indica-
tor will illuminate  in red.

 If you try to turn on the projector
a fourth time without replacing
the lamp, the projector will not 
turn on.

Lamp

It is recommended that the lamp (sold separately) be replaced after approximately 1,900 cumulative 
hours of use or when you notice a significant deterioration of the picture and color quality. The lamp 
usag e time can be  che cked with the on-screen displ ay.  See p ag e  58 .

 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 freq\
uency 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 
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 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- 
PGM20X//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.
