6 Safety, regulatory and legal information
Safety instructions
Your BenQ projector is designed and tested to meet the lastest 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 this manual and marked on the product.
Safety instructions
1. To reduce the risk of electric shock, do not
disassemble this appliance. There are no
user serviceable parts inside. Take it to a
qualified technician when service or repair
is required. Incorrect reassembly can cause
malfunction of the projector or electric
shock when the appliance is subsequently
used.
2. Please read this user’s manual before you
operate your projector. Save this user’s
manual for future reference.
3. Refer servicing only to qualified service
personnel.
4. Always open the lens shutter or remove the
lens cap when the projector lamp is on.
5. Do not look straight at the projector lens
during operation. The intense light beam
may damage your eyes.
6. In some countries, the line voltage is NOT
stable. This projector is designed to
operate safely with a mains voltage
between 100 and 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).

7Safety, regulatory and legal information
Safety instructions (continued)
7. The lamp becomes extremely hot during
operation. Allow the projector to cool for
approximately 45 minutes prior to removing
the lamp assembly for replacement.
8. Do not operate lamps beyond the rated
lamp life. Excessive operation of lamps
beyond the rated life could cause them to
explode on rare occasions.
9. Never replace the lamp assembly or any
electronic components unless the projector
is unplugged.
10. Do not place this product on an unstable
cart, stand, or table. The product may fall,
sustaining serious damage.
11. This product is capable of displaying
inverted images for ceiling mount
installation. Please use BenQ’s Ceiling
Mounting Kit for mounting the projector and
ensure it is securely installed.
12. Do not block the ventilation holes.
- Do not place the projector on a blanket, bedding
or any other soft surface.
- Do not cover the projector with a cloth or any
other item.
- Do not place inflammables near the projector.
If the ventilation holes are seriously obstructed,
overheating inside the projector may cause damage
to the lamp, the projector to fail or result in fire.

8 Safety, regulatory and legal information
Safety instructions (continued)
13. Do not place the projector in any of the
following environments.
- Space that is poorly ventilated or confined. Allow
at least 50 cm clearance from walls and free flow
of air around the projector.
- Locations where temperatures may become
excessively high, such as the inside of a car with
all windows rolled up.
- Locations where excessive humidity, dust, or
cigarette smoke may contaminate optical
components, shortening the projector’s lifespan
and darkening the screen.
- Locations near fire alarms
- Locations with an ambient temperature above
35°C / 95°F
- Locations where altitude are higher than 10000
feet.
14. Always place the projector on a level,
horizontal surface during operation.
- Do not use if tilted at an angle of more than 10
degrees left to right, nor at angle of more than 15
degrees front to back. Using the projector when it
is not fully horizontal may cause a malfunction of,
or damage to, the lamp or other components.
15. Do not stand the projector on end vertically.
Doing so may cause the projector to fall over,
causing injury or resulting in damage to it.
16. Do not step on the projector or place any
objects upon it. Besides probable physical
damage to the projector, doing so may result in
accidents and possible injury.
17. Do not place liquids near or on the projector.

14 Positioning your projector
Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
1. Floor in front of screen;
2. Ceiling in front of screen;
3. Floor at rear of screen; or
4. Ceiling at rear of screen.
Your room layout or personal preference will dictate which installation location you select. Take into
consideration the size and position of your screen, the location of a suitable power outlet, as well as the location
and distance between the projector and the rest of your equipment.
For Setting menu options and descriptions, please refer to page 27.
I. Floor front:
Select this location with the projector placed near the
floor in front of the screen. This is the most common
way to position the projector for quick setup and
portability.
II. Ceiling front:
Select this location with the projector suspended
from the ceiling in front of the screen.
Purchase the BenQ Projector Ceiling Mounting Kit
from your dealer to mount your projector on the
ceiling.
Set in the Setting > Mirror menu after you turn
the projector on.
III. Floor rear:
Select this location with the projector placed near the
floor behind the screen.
Note that a special rear projection screen is required.
Set in the Setting > Mirror menu after you turn
the projector on.
IV. Ceiling rear:
Select this location with the projector suspended
from the ceiling behind the screen.
Note that a special rear projection screen and the
BenQ Projector Ceiling Mounting Kit are required
for this installation location.
Set in the Setting > Mirror menu after you turn
the projector on.

15Positioning your projector
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format each factor in the
projected image size. BenQ has provided separate tables of dimensions for both 16:9 and 4:3 screen ratios to
assist you in determining the ideal location for your projector.
1. Figure out the aspect ration of your screen, 16:9 or 4:3?
2. Select the Screen Size you desire from the 16:9 ration screen dimension table or 4:3 ratio screen dimension
table below, according to what screen type you have. Install the projector at a distance from the screen
corresponding to between the Min. and Max. Projection Distance values in the table.
3. Decide the exact height of your projector.
For example, if you are using a 16:9 screen with 80 inches diagnally, you are suggested to place your projector
within a range between 2.76m to 3.39m from the screen. The exact heigh of your projector will be 33 to 34cm
above or below your screen from the center of the lens.
