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 lens cleaning paper to gently wipe the lens and the cinema 
filter.
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

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.
•
•• •Spare 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 before 
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 or the cinema filter with harsh materials or subject them to 
shocks, as they can easily become damaged.

•
•• •The projected image gets darker or star ts to deteriorate
Lamp Replacement Period
•
•• •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.
Replacing the Lamp
A message will be displayed.
The message appears for 30 seconds, and disappears again 
after 30 seconds have passed.
Power
Flashes red at 0.5-second 
intervals
•
•• •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 fur ther one hour after the cool-down
 period has finished for the lamp to 
be cool enough.

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

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.49)
•
