Maintenance

Cleaning of the ﬁlter

Clean dust from the ﬁlter.

Before cleaning the ﬁlter, be sure to turn off the power

of the projector and unplug the power cord from the

outlet.

Clean the ﬁlter frequently (at least once a month).

Dust settling on the ﬁlter causes the temperature

inside the projector to increase abnormally, damaging

the internal parts and components and affecting the

panel’s lifetime, resulting in a breakdown.

• When the temperature inside the projector is

abnormally high, the projector may automatically

turn off and go into the standby mode where the

light source lamp is off to protect the internal parts

and components.

1. Unplug the power cord.

2. Loosen two screws (a) that is securing the ﬁlter

cover using a Phillips screwdriver and remove the

ﬁlter cover (b) from the projector.

Important:

• The projector doesn’t turn on if the ﬁlter cover isn’t

attached securely.

Warning:

• Do not use ﬂammable solvents (benzene, thinner,

etc.) and ﬂammable aerosols when cleaning the

projector body and lens. Flammable substances

may ignite causing ﬁre or breakdown while the

lamp is illuminating.

Caution:

• Be sure to turn off the lamp and unplug the power

cord from the wall outlet before you perform any

maintenance on the projector.

Cleaning of the projector and the

ventilation slots

Use a soft cloth to clean the projector and the

ventilation grilles. When the grilles become dirty, wipe

them with a soft cloth dampened with diluted mild

detergent, and then wipe them with a dry cloth.

• Clean the inside of the terminal cover frequently as

dust is apt to be collected.

To protect the surface of the projector from fading or

deteriorating:

• Do not spray insecticide on or inside the projector.

• Do not use benzine or thinner to clean it.

• Do not let rubber or plastic materials contact with

projector.

Cleaning of the lens

Use a standard lens-cleaning brush or a piece of lens

tissue dampened with lens cleaning ﬂuid. The lens

surface is fragile. Use only recommended, nonabrasive

lens-cleaning materials. Do not touch the lens with

your ﬁngers.
