Maintenance and Cleaning

Cleaning the RGB panels

Blemishes such as dust and dirt on the internal optical components of the projector tend to degrade the brightness of the
screen and are likely to appear as a shadow on the screen, which can lead to deterioration of image quality.
This projector is equipped with the RGB panel cleaning holes on the underside for cleaning of the internal parts (such as
optical components) of the projector. When you use the projector for a lengthy period of time or a shadow of dust appears
on the projected screen, clean the inside of the projector.
Using the supplied air blower and with the Cleaning function in the Setting Menu (p.38), you can remove the dusts from the
projector.
