Cleaning
Warning:
Never use flammable air duster or other materials when cleaning the air-filter. Flammable substances may ignite
causing fire or breakdown when the lamp is illuminated.

temperature inside the projector may rise abnormally high, causing damage to the internal parts and reducing the
