MaintenanceThis 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.
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.
Turn the projector upside down and use a vacuum cleaner to remove the 
dust from the air filter.Cleaning the Projector CaseCAUTION
Be sure to read the separate Safety Instructions/World-Wide Warranty 
Terms before cleaning.
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.
Cleaning the Lens
Cleaning the Air FilterCAUTION
Do not rub the lens with harsh materials or subject the lens to shocks, 
as it can easily become damaged.
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.

Maintenance Maintenance
It is time to replace the lamp when:
The message Lamp Replace. appears on the screen for 30 
seconds when projection star ts
.When the   (Warning) indicator is flashing red at 0.5-second 
intervals
The projected image gets darker or star ts to deteriorate.Lamp Replacement Period
A message will be displayed.Flashes red at 0.5-second intervals
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.

period to end, and then disconnect the power cable.
The cool-down period lasts for about 20 seconds.Wait 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.
Insert the screwdriver that is supplied with the spare lamp or a 
flat-tipped screwdriver into the gap in between the projector 
and the lamp cover, and slide the screwdriver in until the [ ] 
mark on the lamp cover and the [ ] mark on the projector are 
aligned. Then lift up the lamp cover to remove it.

flat-tipped screwdriver to loosen the two silver lamp fixing 
screws that are securing the lamp to the projector.
