    Safety instructions for ceiling mounting of your BenQ 
    projector
    We want you to have a pleasant experience using your BenQ projector, so we need to bring 
    this safety matter to your attention to prevent damage to person and property.
    If you intend to mount your projector on the ceiling, we strongly recommend that you use a 
    proper fitting BenQ projector ceiling mount kit and that you ensure it is securely and safely 
    installed.
    If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that the 
    projector may fall from the ceiling due to an improper attachment through the use of the 
    wrong gauge or length screws.
    You can purchase a BenQ projector ceiling mount 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 ceiling mount bracket. This will perform the secondary role of 
    restraining the projector should its attachment to the mounting bracket become loose.
