If a laptop computer or a computer with a 
LCD screen has been connected to the 
projector, it is necessary to output the image 
signals to the projector rather than to the 
screen.Normally image signals are output to only the 
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 separate Safety Instructions/ World-Wide Warranty Terms 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.

•
•• •In order to maintain the brightness and quality of the projected images, replace the lamp as 
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 start-up 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.

Procedure
1Turn off the projector power, wait for the 
cool-down
 period to end, and then 
disconnect the power cord. (p.9)
The cool-down period lasts for about 2 minutes. 
The actual time will vary depending on the 
external air temperature.
2Wait until the lamp has cooled down, 
and then remove the lamp cover.
It takes approximately 30 minutes for the lamp to 
cool down by itself. Use the screwdriver that is 
provided with the spare lamp to slide the lamp 
cover opening switch so that the lamp cover lifts 
up. Hold the raised section of the lamp cover and 
then slide it forward to remove it from the 
projector.
3Loosen the two lamp fixing screws.
Use the screwdriver that is supplied with the 
spare lamp to loosen the two lamp fixing screws 
that are securing the lamp to the projector.
4Take out the lamp.
Hold the lamp by the two recesses on the side to 
lift it up and out from the projector.
5Install the new lamp.
Hold the lamp so that it faces the correct way to 
fit into the projector, and then insert the lamp 
until it clicks into place and tighten the two fixing 
screws.
Replacing the Lamp
•
•• •If the lamp stops working and needs to be replaced, there is the danger that the lamp may 
break when handled. 
If replacing the lamp of a projector which has been installed to the ceiling, you should 
remove the projector from the ceiling before replacing the lamp. If the projector cannot be 
removed from the ceiling, you should always assume that the lamp is broken and handle it 
with extreme care during removal. Fur thermore, you should stand to the side of the 
projector, not underneath it.
•
•• •Wait until the lamp has cooled down sufficiently before opening the lamp cover. After the 
cool-down
 period has finished, it takes approximately a further 30 minutes for the lamp to 
be cool enough.
