• There is 3% 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.
• To obtain the clearest image possible, we suggest that you keep the desired distance
within 1.5 to 6 m.
