may cause malfunction.

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.

t
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:

t
Do not spray insecticide on or inside the projector. t
Do not use benzine or thinner to clean it.

t
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.

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.

t
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.
