BenQ TH585 User Manual - Page 14

For example, if you are using a 120-inch screen, the recommended projection distance in the "Average" column is 4184 mm. If your measured projection distance is 4400 mm, the closest match in the "Average" column is 4533 mm. Looking across this row shows that a 130'' (about 3.3 m) screen is required. To optimize your projection quality, we suggest to 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 bracket. This will perform the secondary role of restraining the projector should its attachment to the mounting bracket become loose. • Ask your dealer to install the projector for you. Installing the projector on your own may cause it to fall and result in injury. • Take necessary procedures to prevent the projector from falling off such as during an earthquake. • The warranty doesn't cover any product damage caused by mounting the projector with a non-BenQ brand projector mounting kit. • Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater is used, the temperature around the ceiling may be higher than expected. • Read the user manual for the mounting kit about the range of torque. Tightening with torque exceeding the recommended range may cause damage to the projector and subsequently falling off. • Make sure the power outlet is at an accessible height so that you can easily shut down the projector. 14 Positioning your projector
