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 this manual and marked on the product.
Safety Instructions
1. Do not look straight at the projector lens during operation. The intense light beam may damage your
eyes.
2. Always open the lens shutter or remove the lens cap when the projector lamp is on.
3. 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 uctuate or cut out, it is recommended that you connect your
projector through a power stabilizer, surge protector or uninterruptible power supply (UPS).
4. 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 re. Press ECO BLANK
on the remote control to turn off the lamp temporarily.
5. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining serious
damage.
6. Do not attempt to disassemble this projector. There are dangerous high voltages inside which may
cause death if you should come into contact with live parts.
Under no circumstances should you ever undo or remove any other covers. Refer servicing only to
suitably qualied professional service personnel.
7. Do not place this projector in any of the following environments.
y Space that is poorly ventilated or conned. Allow at least 50 cm clearance from walls and free
ow of air around the projector.
y Locations where temperatures may become excessively high, such as the inside of a car with all
windows rolled up.
y Locations where excessive humidity, dust, or cigarette smoke may contaminate optical
components, shortening the projector's life span and darkening the image.
y Locations near re alarms
y Locations with an ambient temperature above 40°C / 104°F
y Locations where the altitudes are higher than 5000 m (16400 feet).
8. Do not block the ventilation holes.
y Do not place this projector on a blanket, bedding or any other soft surface.
y Do not cover this projector with a cloth or any other item.
y Do not place inammables near the projector.
If the ventilation holes are seriously obstructed, overheating inside the projector may result in a re.
English
7
9. 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.
10. Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail. If
the projector does become wet, disconnect it from the power supply's wall socket and call BenQ to
have the projector serviced.
Do not remove it.
This device comes with the three-pin power plug with earth contact. Do
not remove the earth contact pin. As a safety function, this power plug
may only be inserted into the power socket with earth wire. Contact the
electrician if the plug cannot be inserted into the power socket.

Effective range of remote control
Infra-Red (IR) remote control sensors are located on the front and rear of the projector. The remote
control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control
sensor to function correctly. The distance between the remote control and the sensor should not
exceed 8 meters (~ 26 feet).

Replacing the remote control battery
1. To open the battery cover, turn the remote control over to view its back, push on the nger grip on
the cover and slide it up in the direction of the arrow as illustrated. The cover will slide off.
2. Remove any existing batteries (if necessary) and install two AAA batteries observing the battery
polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and
negative (-) goes to negative.
3. Ret the cover by aligning it with the base and sliding it back down into position. Stop when it clicks
into place.
Caution:
y Avoid excessive heat and humidity.
y There may be battery damage if the battery is incorrectly replaced.
y Replace only with the same or equivalent type recommended by the battery manufacturer.
y Dispose of the used battery according to the battery manufacturer’s instructions.
y Never throw a battery into a re. There may be danger of an explosion.
y If the battery is dead or if you will not be using the remote control for a long time, remove the battery to prevent damage to
the remote control from possible battery leakage.

Installation
Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
1.Front Table
Select this location with the projector placed near
the oor in front of the screen. This is the most
common way to position the projector for quick
setup and portability.
2.Rear Table
Select this location with the projector placed near
the oor behind the screen.
Note that a special rear projection screen is
required.
* Set Rear Table in the SYSTEM SETUP:
Basic > Projector Installation menu after you
turn the projector on.
3.Front Ceiling
Select this location with the projector suspended
upside-down 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 Front Ceiling in the SYSTEM SETUP:
Basic > Projector Installation menu after you
turn the projector on.
4.Rear Ceiling
Select this location with the projector suspended
upside-down 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 Rear Ceiling in the SYSTEM SETUP:
Basic > Projector Installation menu after you
turn the projector on.
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.

Evaluate the distance based on the image size
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and the video format
each factors in the projected image size.

Note:
A 5-percent tolerance exists between these numbers due to the difference among optical components. 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. To optimize the projection quality,
we suggest to project images in an area without grayscale.
