4Important safety instructions
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.
1. Please read this manual 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 qualied service
personnel.
4. 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).
5. 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. To temporarily turn off the
light source, press ECO BLANK on the
remote control.
English

Important safety instructions
9. 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.
10. When the projector is under operation,
you may sense some heated air and odor
from its ventilation grill. It is a normal
phenomenon and not a product defect.
11. Do not place this projector in any of the
following environments.
- Space that is poorly ventilated or conned. Allow
at least 50 cm clearance from walls and free ow
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 life span
and darkening the image.
6. Do not operate projector beyond the rated
light source life, Excessive operation of light
source beyond the rated life could cause
them to break on rare occasions.
7. Never replace any electronic components
unless the projector is unplugged.
8. Do not place this product on an unstable
cart, stand, or table. The product may fall,
sustaining serious damage.
English
6Important safety instructions
- Locations near re alarms
- Locations with an ambient temperature above
40°C / 10F
- Locations where the altitudes are higher than
3000 m (10000 feet).
3000 m
(10000 feet)
0 m
(0 feet)
12. Do not block the ventilation holes.
- Do not place this projector on a blanket, bedding
or any other soft surface.
- Do not cover this projector with a cloth or any
other item.
- Do not place inammables near the projector.
If the ventilation holes are seriously
obstructed, overheating inside the projector
may result in a re.
13. Do not stand the projector on end
vertically. Doing so may cause the projector
to fall over, causing injury or resulting in
damage to the projector
14. 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.
15. 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.

Important safety instructions
16. This product is capable of displaying inverted
images for wall mount installation.
Use only BenQ's Wall Mount Kit for
mounting the projector and ensure it is
securely installed.
Wall mounting the 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
possible damage to person and property.
If you intend to mount your projector on the
wall, we strongly recommend that you use a
proper tting BenQ projector wall mount kit and
that you ensure it is securely and safely installed.
If you use a non-BenQ brand projector wall
mount kit, there is a safety risk that the projector
may fall from the wall due to an improper
attachment through the use of the wrong gauge
or length screws.
You can purchase a BenQ projector wall 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 wall mount bracket. This will perform
the secondary role of restraining the projector
should its attachment to the mounting bracket
become loose.
English
8Important safety instructions

14 Introduction
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.
Avoid excessive heat and humidity.
There may be battery damage if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the battery manufacturer.
Dispose of the used battery according to the battery manufacturers instructions.
Never throw a battery into a re. There may be danger of an explosion.
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.
Remote control effective range
Infra-Red (IR) remote control sensor is 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).
Make sure that there are no obstacles between the remote control and the IR sensor on the
projector that might obstruct the infra-red beam.

There is 5% tolerance among these numbers due to optical component variations. BenQ recommends that
if you intend to permanently install the projector, you should physically test the projection size and distance
using the actual projector 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..
It is recommended to adjust focus 15 minutes after powering on due to the slight shifting of the lens from
temperature changing.

Positioning your projector
Mounting the projector
If you intend to mount your projector, we strongly recommend that you use a proper tting 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
Use BenQ Projector Wall Mounting Kit come with the package. Please refer to the User manual
in the box of wall mount kit for installation details.
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
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/wall 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.
Install the projector on the projector wall mount
