Note
• Position the projector in a horizontal position; other positions can cause heat build-up
and damage to the projector.
• Keep a space of 30 cm or more between the sides of the projector.
• Do not use the projector in a smoky environment. Smoke residue may build-up on
critical parts and damage the projector or its performance.
• There is 10% tolerance among these numbers due to optical component variations. It is
recommended that if you intend to permanently install the projector, you should
physically test the projection size and distance using the actual projector in situ before
you permanently install it, so as to make allowance for this projector's optical
characteristics. This will help you determine the exact mounting position so that it best
suits your installation location.
