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
build-up on critical parts (i.e. DMD, lens assembly, etc.)
