							Carrying the Projector
How to Use the
Carrying Case
When transporting the projector, make sure
to retract the antenna, cover the lens with the
lens cap, and place the projector in the
included 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.
•Make sure that the antenna for the
GyroRemote is fully retracted.
•Make sure that the Eject button is
fully inserted.
•
Make sure to turn the off the projector.
Info
•This carrying case is only for storing and car-
rying the projector.
•Shipping the projector in the carrying case as
a parcel may cause damage to the projector.
If you ship the projector, 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 projector
to direct sunlight, near heat sources, or in an
enclosed automobile. The carrying case or pro-
jector may change color or become deformed.
•When moving the projector, make sure the
Eject button is pressed all the way in.
If moved with the Eject button out, the projector
may be damaged.

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
usage time can be checked with the on-screen display. See page 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 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
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-
PGM25X//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.
