45Cleaning the RGB panelsBlemishes such as dust and dirt on the internal optical components of the projector tend to degrade the brightness of thescreen and are likely to appear as a shadow on the screen, which can lead to deterioration of image quality.This projector has the RGB panel cleaning holes on the underside for cleaning of the internal parts (such as opticalcomponents) of the projector. When you use the projector for a lengthy period of time or a shadow of dust appears on theprojected screen, clean the inside of the projector.Using the supplied air blower and with the Cleaning function in the Setting Menu (p.42), you can remove the dusts from theprojector.CAUTION IN USING THE AIR BLOWER AND THE NOZZLE● Turn the projector over when using the blower.● Use only the supplied air blower and nozzle to keep the projector from being out of order ordamaged. We could not guarantee the malfunction or breakage caused by other tools.● Never use a commercially available compressed air duster.
