removable air filter prevents dust from accumulating on the surface of projection lens and projection mirror. should air filter become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector. clean air filter following the steps below:

    1 turn off the projector, and disconnect ac power cord from the ac outlet.

    2 turn the projector upside down and remove air filter by pulling the latches upward.

    do not put small parts into air intake vents. it may result in malfunction of the projector.

    recommendation

    we recommend avoiding dusty/smoky environment when operating a projector. usage in these environments may cause poor image quality.

    when using under dusty or smoky conditions, dust may accumulate on the lens, liquid crystal panels, or optical elements inside the projector. this condition may degrade the quality of a projected image.
