High temperature 
inside projector 
(overheating)The lamp will turn off automatically and projection will stop. 
Wait for about 5 minutes without operating the projector. After 5 
minutes have elapsed, the projectors cooling fan will stop. When 
the cooling fan stops, turn off the main power switch and then 
turn it back on again.
If the projector overheats, check the following two points.
•
•• •Is the setting-up location well ventilated?
Check that the air inlet and air outlet are clear, and that the 
projector is not positioned against a wall.
•
•• •Is the air filter blocked with dust?
If the air filter is dirty, it should be cleaned.
When the main power switch is turned back on, the projector will 
return to its previous state, so press the [STANDBY/ON] button 
on either the remote control or the projectors control panel to turn 
it back on. If the projector continues to overheat even after the 
above points have been checked, or if the indicators show a 
problem when the power is turned back on, stop using the 
projector, turn off the main power switch, disconnect the power 
cord from the electrical outlet, and contact your dealer.

again, projection will stop automatically.)
•
•• •Set the projector up in a place which is well-ventilated, and so 
that the air inlet and exhaust vents are clear.
•
•• •Clean the air filter.* The appearance of the   indicator at this time will vary 
depending on the status of the projector.

computers LCD screen, so you need to change the 
output to an external destination. For some computer 
models, when the image signals are output externally, 
they no longer appear on the LCD screen. For details, 
refer to the section of the documentation provided with 
your computer under a heading such as External 
output, Connecting an external monitor or similar.

Maintenance
This section describes maintenance tasks such as cleaning the projector and replacing consumable parts.
You should clean the projector if it becomes dirty or if the quality of projected images starts to deteriorate.
Clean the projector case by wiping it gently with a soft cloth. 
If the projector is particularly dirty, moisten the cloth with water containing a small amount of neutral 
detergent, and then firmly wring the cloth dry before using it to wipe the projector case. Then wipe the case 
again with a soft, dry cloth.
Use a commercially-available air blower, or use a lens cleaning paper to gently wipe the lens.
If the air filter becomes clogged with dust, it can cause overheating and damage the projector. 
Stand up the projector in order to prevent dust getting inside the projector, and then use a vacuum cleaner to 
clean away the dust from the air filter.
Cleaning
Cleaning the Projector Case
Cleaning the Lens
Cleaning the Air Filter
•
•• •If the air filter is difficult to clean or if it is broken, 
it should be replaced. Contact your dealer for a 
spare air filter.
•
•• •Replacement lamps are provided with a spare 
air filter. The air filter should also be replaced 
when the lamp is replaced.
Be sure to read the Safety Instructions in this manual for details on safe handling of 
the projector during cleaning.
Do not use volatile substances such as wax, alcohol or thinner to clean the projector 
case. These can cause the case to warp and make the coating finish peel off.
Do not rub the lens with harsh materials or subject the lens to shocks, as it can 
easily become damaged.

soon as possible after the warning message appears.
•
•• •The replacement warning message is set to appear after 2900 hours of lamp use in order to 
maintain the brightness and quality of the projected images. If you continue to use the lamp after 
this period, the possibility of the lamp breaking becomes greater. When the lamp replacement 
message appears, replace the lamp with a new one as soon as possible, even if it is still 
working.
•
•• •The warning message appears after 2900 hours of use, but the actual life of each individual 
lamp will vary depending on the characteristics of the lamp and on the way it has been used. 
Some lamps may stop operating before 2900 hours of use, so you should always have a spare 
lamp ready in case.
•
•• •When the lamp replacement warning message appears, the users logo will not appear even if 
the “Startup Screen” setting is “ON”.
•
•• •Contact your dealer for a spare lamp.
A message will be displayed.
The message appears for 30 seconds, and disappears again 
after 30 seconds have passed.
