MAINTENANCE
Cleaning and Replacing the Air Filter
An air filter is installed in the air intake vent on the bottom of the main body to protect the
internal lens and mirror from dust. Should the air filter become clogged with dust, the pro-
jector may be damaged since it will block the air flow into the projector and raises the inter-
nal temperature of the projector.
Cleaning the Air Filter
Turn the projector upside down, remove the cover by pushing the latch, remove the air fil-
ter, and clean it with a vacuum cleaner.
When cleaning dust off the side exhaust vent and the bottom air intake vent, bring the vac-
uum cleaner nozzle close to them directly.
Replacing the Air Filter
1Turn off the projector, remove the power 
plug from the AC outlet, and let the pro-
jector stand for at least 1 hour.
2Remove the filter cover by pushing the
position of the arrow.
3Remove the air filter.
4Install a new air filter.
5Install the filter cover securely without any
space.
Caution
zThe main unit is very hot immediately after turning off the projector. Wait until the pro-
jector cools down sufficiently (more than 1 hour) before cleaning the projector. Other-
wise, you may get burned or injured.
zBefore cleaning or replacing the air filter, be sure to remove the power plug from the
AC outlet. Otherwise, electric shock or fire may result.
zDo not insert any object into the projector through the air filter opening. You may suffer
electric shock or injury due to the high-voltage parts or rotating parts.
zClean the air filter frequently.
zAfter cleaning the air filter, install it by following the removal steps 1 to 5 in reverse.
zAttach the lens cap when replacing the air filter.
zHandle the air filter carefully. If damaged, the air filter will not work appropriately.
zReplace the air filter whenever you replace the lamp.
zAn air filter can be ordered from your dealer.

abnormalityThe temperature inside the projector is too high for some rea-
son or the outside air temperature is higher than the specified
one. If the problem is inside the projector, check whether the
projector is installed and operated normally, unplug the pro-
jector from the power outlet to cool down the inside of it and
retry projection. If the air intake or exhaust vent is blocked,
remove the obstacle. If the same warning occurs again, the
projector may be defective. Contact your dealer.

Cause Countermeasure
The power cord is not connected
correctly.Check whether the power cord is connected correctly (P40).
The power cord has just been con-
nected.You cannot turn on the projector until the [POWER] indicator
turns red after connecting the power plug (P40).
You attempted to turn on the pro-
jector immediately after turning it
off.The projector cannot be turned on for a while after it is turned
off. Wait for a while before pressing the [POWER] button again
(P60).
The safety device has activated
because you put the projector in
the carrying bag during the cooling
fan was rotating.You cannot release the safety device. Contact your dealer.
The safety device is activated
because the air intake or the
exhaust vent is blocked and the
internal temperature of the projec-
tor is increased.You cannot release the safety device for safety reasons. Con-
tact your dealer.
Cause Countermeasure
Any connection cable is connected
incorrectly.Check whether the projector is connected to the computer or
AV equipment correctly (P36, 64).

played for approximately 20 seconds. To project an image
immediately, press the [OK] button on the remote control or
top control (P40).
No image is sent from the AV
equipment.Check that an image is played on the connected digital cam-
era, video camcorder, DVD, etc.

correctly.Check the cable connection of the audio cable (P38).
The [MUTE] function is enabled. Press the [MUTE] button on the remote control (P79).
The volume level is adjusted to the
minimum.Press the [VOL+] button on the remote control or top control to
adjust the volume level (P79).
An audio cable with a built-in resis-
tor is used.Use an audio cable without a built-in resistor.
Cause Countermeasure
The image is out of focus. Adjust the focus (P51).
The lens cap is not removed. Remove the lens cap.
The distance to the screen is too
short.Check whether the distance to the screen is appropriate. If the
distance is shorter than approximately 1.2 m (3.9), the projec-
tor cannot focus on the screen (P32, 133).
The projector is not placed straight
in front of the screen.Check whether the projector is placed obliquely to the screen.
A slight error in the projection angle can be corrected through
the keystone adjustment function (P43, 52).
The projector has been moved to a
place where the temperature varies
a lot.When the projector is moved from a low-temperature place to
a high-temperature place, condensation may form on the lens.
The condensation will evaporate a while later and the projec-
tor will be able to project a normal image.
The lens is stained. Clean up the lens (P120).
Cause Countermeasure
The projected image is inverted in
the vertical or horizontal direction.The ceiling mounted/rear projection setting is incorrect. Check
the [Image flip H/V] setting in the [Display settings] menu
(P97).

The output setting method varies among computer manufac-
turers. For more detailed information, refer to the Users Man-
ual that came with your computer.
Cause Countermeasure
The air intake or exhaust vent is
blocked.Check whether the air intake or exhaust vent is blocked. If the
air intake or exhaust vent is blocked, the temperature inside
the projector rises and the power is automatically turned off to
protect the projector. Wait until the internal temperature gets
down, and then turn on the projector without blocking the
intake and exhaust vents (P22, 23, 40).
The air filter is dirty. Check whether the bottom air filter is clogged with dust.
