Adjusting Projection Image Size
Refer to the graphic and table below to determine the screen size and projection
distance.
Position the projector in a horizontal position; other positions can cause heat
build-up and damage to the projector.
Make sure the heat ventilation holes are not blocked.
Do not use the projector in a smoky environment. Smoke residue may cause
buildup on critical parts.
