When “Please clean the filter.” appears on 
the screen, you should clean the air filter.
The air filter should be cleaned every 1,250 
hours. This value varies depending on the 
environment or how the projector is used. 
1,250 hours are approximate.
Clean the air filter with a vacuum cleaner. If 
the dust still remains, wash the air filter with 
a mild detergent solution and dry it in a 
shaded place.

• Be careful that the filter does not get caught 

in the vacuum cleaner.

• When you clean the air filter, make sure you 

do not damage it.
For details on how to attach and remove the 
air filter, see “Replacing the Lamp and the 
Air Filter and cleaning the Ventilation holes 
(intake)” Steps 13 to 16. (

• When you remove the air filter, be careful 

not to let any dust fall into the projector.

• Cleaning the air filter is crucial to maintain 

the good performance of the projector or to 
prevent malfunction to it. When a warning 
message for cleaning the air filter appears, 
clean the air filter immediately.

Cleaning the lens
The lens surface is especially treated to 
reduce reflection of light.
As incorrect maintenance may impair the 
performance of the projector, take care with 
respect to the following:
• Wipe the lens gently with a soft cloth such 

as a cleaning cloth or glass cleaning cloth.

• Stubborn stains may be removed with a 

soft cloth such as a cleaning cloth or glass 
cleaning cloth lightly dampened with 
water.

• Never use solvent such as alcohol, 

benzene or thinner, or acid, alkaline or 
abrasive detergent, or chemical cleaning 
cloth, as they will damage the lens surface.

Cleaning the cabinet
• To remove dust from the cabinet, wipe 

gently with a soft cloth. If dust is 
persistent, wipe with a soft cloth slightly 
moistened with a diluted mild detergent 
solution.

• Never use any type of abrasive pad, 

alkaline/acid cleaner, scouring powder, or 
volatile solvent, such as alcohol, benzene, 
thinner or insecticide. 

• Using such materials or maintaining 

prolonged contact with rubber or vinyl 
materials may result in damage to the 
screen surface and cabinet material.

Black points and bright points (red, 
blue, or green) on the screen
The projector is manufactured using high-
precision technology. 
You may, however, see tiny black points 
and/or bright points (red, blue, or green) that 
continuously appear on the projector.
This is a normal result of the manufacturing 
process and does not indicate a malfunction.
