Important safety instructions
Your projector is designed and tested to meet the latest standards for safety of information technology
equipment. However, to ensure safe use of this product, it is important that you follow the instructions
mentioned in the user manual / installation guide and marked on the product.
1. Please read the user manual / installation guide before you operate your projector. Save
it for future reference.
2. Do not look straight at the projector lens during operation. The intense light beam may
damage your eyes.
3. Refer servicing to qualified service personnel.
4. Always open the lens shutter (if any) or remove the lens cap (if any) when the
projector light source is on.
5. The light source becomes extremely hot during operation.
6. In some countries, the line voltage is NOT stable. This projector is designed to operate safely
within a mains voltage between 100 to 240 volts AC, but could fail if power cuts or surges of ±10
volts occur. In areas where the mains voltage may fluctuate or cut out, it is
recommended that you connect your projector through a power stabilizer, surge
protector or uninterruptible power supply (UPS).
7. Do not block the projection lens with any objects when the projector is under operation as this
could cause the objects to become heated and deformed or even cause a fire. To temporarily turn
off the light source, use the blank function.
8. Do not operate light sources beyond the rated light source life.
9. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining
serious damage.

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.
15 Installation
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 security cable and attach it securely to both the
security bar 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 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.

Shifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the projector to be
positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image height or width. You can turn the
knobs on the projector to shift the projection lens in any direction within the allowable range depending
on your desired image position.
• Lens shift adjustment will not result in a degraded picture quality.
• Please stop turning the adjustment knob when you hear a clicking sound indicating that the knob has reached its
limit. Over-turning the knob may cause damage.
