There is 5% tolerance among these numbers due to optical component variations. BenQ recom-
mends 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 itbest suits your installation location.
It is recommended to adjust focus 15 minutes after powering on due to the slight shifting of
the lens from temperature changing.
