Maintenance
This section describes maintenance tasks such as cleaning the projector and 
replacing consumable parts.
Cleaning
You should clean the projector if it becomes dirty or if the quality of projected 
images starts to deteriorate.
Caution :
Be sure to read the separate Safety Instructions/World-Wide Warranty Terms before 
cleaning.
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.
Caution :
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.
Use a commercially-available air blower, or use a lens cleaning paper to gently
wipe the lens.
Caution :
Do not rub the lens with harsh materials or subject the lens to shocks, as it can easily 
become damaged.

If the air filter becomes clogged with dust, it can cause overheating and damage 
the projector.
Turn the projector upside down and use a vacuum cleaner to remove the dust 
from the air filter.
Tip :
 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.
 Spare lamps are provided with a spare air filter. The air filter should also be replaced 
when the lamp is replaced.

Replacing Consumables
This section describes how to replace the remote control battery, the lamp and 
the air filter.
Use the following type of battery as a replacement.
    1 CR2025 lithium battery
Caution :
Be sure to read the Safety Instructions/World-Wide Warranty Terms before handling the 
battery.
Procedure
1Remove the battery holder.
While pushing the catch of the battery 
holder inwards, pull the battery holder out.
2Remove the old battery and insert 
the new battery.
Check the position of the (+) mark inside 
the battery holder to ensure that that 
battery is inserted the correct way.

It is time to replace the lamp when:
The message Lamp Replace appears on the screen for 30 seconds 
when projection starts
.
When the   (Warning) indicator is flashing red at 0.5-second intervals
The projected image gets darker or starts to deteriorate
Tip :
 The replacement warning message is set to appear after about 1400 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 about 1400 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 1400 hours of use, so you 
should always have a spare lamp ready in case.
 Contact your dealer for a spare lamp.

Caution :
 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 that has been installed to the ceiling, you should 
always assume that the lamp is broken and remove the lamp cover very carefully.
 Wait until the lamp has cooled down sufficiently before opening the lamp cover. It takes 
a further one hour after the cool-down
 period has finished for the lamp to be cool 
enough.
Procedure
1Turn off the projector power, wait 
for the cool-down period to end, 
and then disconnect the power 
cable.
The cool-down period lasts for about 20 
seconds. The actual time will vary 
depending on the external air temperature.
2Wait until the lamp has cooled 
down, and then remove the lamp 
cover from the base of the 
projector.
It takes approximately one hour for the 
lamp to cool down by itself after the cool-
down period has finished.
Put your finger into the recess, and pull 
straight out to remove the lamp cover.
3Loosen the two lamp fixing screws.
Use the screwdriver that is supplied with 
the spare lamp or a Phillips screwdriver 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 tabs 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 and tighten the two lamp 
fixing screws.
6Install the lamp cover.
Slide the cover in from the outside, and 
then push it in until it clicks into place.
Tip :
 Install the lamp securely. If the lamp cover is removed, the lamp turns off automatically 
as a safety precaution. Moreover, the lamp will not turn on if the lamp or the lamp 
cover is not installed correctly.
 Spare lamps are provided with a spare air filter. The air filter should also be replaced 
when the lamp is replaced. (p.79)
 Dispose of used lamps properly in accordance with your local regulations.
The projector has a built-in counter which keeps track of the lamp operating 
time. When the cumulative operating time reaches a certain point, it causes the 
replacement warning message to be displayed. Therefore, the counter needs to 
be reset after the lamp has been replaced with a new one. You can do this using 
the configuration menu.
Tip :
Do not reset the lamp operating time except after the lamp has been replaced, otherwise 
the lamp replacement period will not be indicated correctly.
