TR: 1.15~1.9, offset = 115%

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 determinethe exact mounting position so that it

best suits your installation location.

To optimize the projection quality, we suggest to project images in an area without

grayscale.

To avoid damaging the DLP chips, never aim a high-power laser beam into the

projectiom lens.
