Replacing the Air
Filter
When “Please replace the filter.” appears on
the screen, you should replace the air filter.
The air filter should be replaced every 1,500
hours. This value varies depending on the
environment or how the projector is used.
1,500 hours are approximate.
• 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 7 to 11. (1 page 56)
• When you remove the air filter, be careful
not to let any dust fall into the projector.
• Replacing the air filter is crucial to maintain
the good performance of the projector or to
prevent malfunction to it. When a warning
message for replacing the air filter appears,
replace the air filter immediately.
Fitting the lens cap
When fitting the lens cap onto the lens,
position the lens cap so that the concave on
the side of the lens cap will fit the zoom
lever, as shown in the illustration.
The lens cap will not fit if the position is not set
correctly.
Cleaning and the
Screen of the
Projector
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.
