Note:
There is 5% tolerance among these numbers due to optical component variations. BenQ recommends that if you
intend to permanently install the projector, you should physically test the projection size and distance using the actual
projector 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.
