• 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.
• Ceiling installation must be done by a qualified professional. Contact your dealer for more information. It is not
recommended you install the projector yourself.
• Only use the projector on a solid, level surface. Serious injury and damage can occur if the projector is dropped.
• Do not use the projector in an environment where extreme temperature occurs. The projector must be used at
temperatures between 32 degrees Fahrenheit (0 degrees Celsius) and 104 degrees Fahrenheit (40 degrees
Celsius).
• Screen damage will occur if the projector is exposed to moisture, dust or smoke.
• Do not cover the vents on the projector. Proper ventilation is required to dissipate heat. Damage to the projector
will occur if the vents are covered.
