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
• Use BenQ Projector Wall Mounting Kit come with the package. Please refer to
the User manual in the box of wall mount kit for installation details.
• 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.
Install the projector on the projector wall mount
1. Slide the projector into the wall mount.
