If your measured projection distance is 6300 mm, the closest match in the "Projection distance (mm)" column is 6300 mm. Looking across this row shows that a 180'' (about 4.6 m) screen is required. • To optimize your projection quality, we suggest you do the projection within non-gray area. • All measurements are approximate and may vary from the actual sizes. 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. Mounting the projector If you intend to mount your projector, we strongly recommend that you use a proper fitting BenQ projector mounting kit and that you ensure it is securely and safely installed. If you use a non-BenQ brand projector mounting kit, there is a safety risk that the projector may fall down due to an improper attachment through the use of the wrong gauge or length screws. Before mounting the projector • Purchase a BenQ projector mounting kit from the place you purchased your BenQ projector. • BenQ recommends that you also purchase a separate Kensington lock compatible security cable and attach it securely to both the Kensington lock slot on the projector and the base of the mounting 14 Positioning your projector
