Positioning your projector 17
There is 3% 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 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.
