■ Use a vacuum cleaner to clean dust from the ex-

haust vent, the intake vents and the intake vent
cover (on the bottom of the projector).

• If you want to clean the air vents and the intake

vent cover during projector operation, ensure
to press 

 on the projector or 

 on the

remote control and put the projector into standby
mode. After the cooling fan has stopped, un-
plug the power cord from the AC socket and
clean the air vents and the intake vent cover.

■ Ensure the power cord is unplugged before cleaning

the projector.

■ The cabinet as well as the operation panel is made

of plastic. Avoid using benzene or thinner, as these
can damage the finish on the cabinet.

■ Do not use volatile agents such as insecticides on

the projector.
Do not attach rubber or plastic items to the projec-
tor for long periods.
The effects of some of the agents in the plastic may
cause damage to the quality or finish of the projector.

■ Wipe off dirt gently with a soft flannel cloth.

■ When the dirt is hard to remove, soak a cloth in a

mild detergent diluted with water, wring the cloth
well and then wipe the projector.
Strong cleaning detergents may discolor, warp or
damage the coating on the projector. Make sure to
test on a small, inconspicuous area on the projec-
tor before use.

■ Use a commercially available blower or lens clean-

ing paper (for glasses and camera lenses) for clean-
ing the lens. Do not use any liquid type cleaning
agents, as they may wear off the coating film on the
surface of the lens.

■ As the surface of the lens can easily get damaged,

ensure not to scrape or hit the lens.

• The air vents and the intake vent cover should be

cleaned every 100 hours of use. Clean the air vents
and the intake vent cover more often when the pro-
jector is used in a dusty or smoky location.

• Ensure the intake vent cover is securely installed.

The power will not turn on unless it is correctly in-
stalled.

Maintenance Indicators

■ The warning lights on the projector indicate problems inside the projector.

■ If a problem occurs, either the temperature indicator or the lamp indicator will illuminate red, and

If the temperature inside the projector increases, due to blockage of the air vents, or the setting location,

“

” will illuminate in the lower left corner of the picture. If the temperature keeps on rising, the lamp will

turn off and the temperature warning indicator will blink, the cooling fan will run for a further 90 seconds, and

then the projector will enter the standby mode. After “

” appears, ensure to perform the measures

described on page 92.

“Change The Lamp. (LAMP 2)” is displayed when the remain-
ing life of the lamp 2 becomes 5% or less.

■ When the remaining lamp life becomes 5% or less, “

” (yellow) and “Change The Lamp. (LAMP 1/

2)” will be displayed on the screen. When the percentage becomes 0%, it will change to “

” (red),

the lamp will automatically turn off. At this time, the lamp indicator will illuminate in red.

■ If you try to turn on the projector a fourth time without replacing the lamp, the projector will not turn on.
