BenQ HT5550 User Manual - Page 14

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 use a security cable to secure both the base of the mounting bracket and the security bar on the projector. 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 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.
