Important safety instructions 1
Important safety instructions
Your BenQ 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.
Caution
• To prevent shock, do not open the
cabinet. There are no user serviceable
parts inside.
• Please read this user’s manual before
you operate your projector. Save this
user’s manual for future reference.
• Do not look straight at the projector
lens during operation. The intense
light beam may damage your eyes.
• Refer servicing to qualified service
personnel.
• Always open the lens shutter or
remove the lens cap when the
projector lamp is on.
• 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).
Important safety instructions2
Safety Instructions
1. The lamp becomes extremely hot
during operation. Allow the
projector to cool for approximately
45 minutes prior to removing the
lamp assembly for replacement.
2. Do not operate lamps beyond the
rated lamp life. Excessive operation
of lamps beyond the rated life could
cause them to break on rare
occasions.
3. Never replace the lamp assembly or
any electronic components unless
the projector is unplugged.
4. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.
5. To reduce the risk of electric shock,
do not disassemble this appliance.
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.
Important safety instructions 3
Safety Instructions (Continued)
6. Do not place this 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 life span and darkening the
image.
- Locations near fire alarms
- Locations with an ambient temperature
above 40°C / 104°F
- Locations where the altitudes are higher
than 10000 feet.
7. Do not block the ventilation holes.
- Do not place this unit on a blanket,
bedding or any other soft surface.
- Do not cover this unit with a cloth or any
other item.
- Do not place inflammables near the
projector.
If the ventilation holes are seriously
obstructed, overhe ating inside the unit
may result in a fire.
8. Always place the unit 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 unit when it is not fully
horizontal may cause a malfunction of, or
damage to, the lamp.
9. Do not stand the unit on end vertically.
Doing so may cause the unit to fall over,
causing injury or resulting in damage to
the unit.
Important safety instructions4
Safety Instructions (Continued)
10. 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.
11. 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 lamp, press Blank on the
projector or remote control.
12. 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.
13. This product is capable of displaying
inverted images for ceiling mount
installation.
Please use BenQ’s Ceiling Mount Kit
for mounting the unit and ensure it is
securely installed.
14. 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.

Introduction12
Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the back of the projector.
The remote control must be held at an angle within 30 degrees of the projector’s IR remote
control sensors to function correctly. The distance between the remote control and the
sensors should not exceed 6 meters (~ 20 feet).
Make sure that there are no obstacles between the remote control and the IR sensors on the
projector that might obstruct the infra-red beam.
Replacing the remote control battery
1. Pull out the battery holder.
2. Insert the new battery in the holder. Note
the positive polarity should face outward.
3. Push the holder into the remote control
until 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 manufacturer’s instructions.
• Never throw a battery into a fire. 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.
• Operating the projector from the
front

Positioning your projector 13
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;
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.
If you use the projector with wireless function, there's no need to worry about data cable
connections.This gives you the flexibility to site the projector anywhere in the room up to a
range of 20m away from your notebook, and switch between presentations on different
notebooks instantly without fiddling with cables
To use the wireless function, you need to install a BenQ wireless module to the projector and
enable your notebook/desktop PC with wireless connection. For more information, refer to
"Wireless connection (optional)" on page 18.
