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.  
Please read this manual before  
you operate your projector. Save  
it for future reference.  
5.  
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).  
2.  
Do not look straight at the  
projector lens during operation.  
The intense light beam may damage  
your eyes.  
6.  
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  
ECO BLANK.  
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 lamp is  
on.

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.  
10. Do not place this product on an  
unstable cart, stand, or table. The  
product may fall, sustaining serious  
damage.  
11. 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. The only user serviceable  
part is the lamp which has its own  
removable cover.  
8.  
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.  
Under no circumstances should you  
ever undo or remove any other  
covers. Refer servicing only to  
suitably qualified professional service  
personnel.  
9.  
Never replace the lamp assembly or  
any electronic components unless the  
projector is unplugged.  
12. 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.

Safety Instructions (Continued)  
17. 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.  
Ceiling 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 ceiling, we strongly recommend  
that you use a proper fitting BenQ  
projector ceiling mount kit and that  
you ensure it is securely and safely  
installed.  
If you use a non-BenQ brand projector  
ceiling mount kit, there is a safety risk  
that the projector may fall from the  
ceiling due to an improper attachment  
through the use of the wrong gauge or  
length screws.  
You can purchase a BenQ projector  
ceiling 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 ceiling  
mount bracket. This will perform the  
secondary role of restraining the  
projector should its attachment to the  
mounting bracket become loose.  
18. 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  
power outlet and call BenQ to have  
the projector serviced.  
19. This product is capable of displaying  
inverted images for ceiling mount  
installation.  
Hg - Lamp contains mercury. Manage in  
accordance with local disposal laws. See  
Use only BenQ's Ceiling Mount Kit for  
mounting the projector and ensure it is  
securely installed.  
20. This apparatus must be earthed.

Adjusting Sharpness  
The higher the value, the sharper the picture becomes. The lower the value, the softer the  
picture becomes.  
Adjusting Brilliant Color  
This feature utilizes a new color-processing algorithm and system level enhancements to  
enable higher brightness while providing truer, more vibrant colors in picture. It enables a  
greater than 50% brightness increase in mid-tone images, which are common in video and  
natural scenes, so the projector reproduces images in realistic and true colors. If you  
prefer images with that quality, select On. If you don’t need it, select Off.  
When Off is selected, the Color Temperature function is not available.

3D Color Management  
In most installation situations, color management will not be necessary, such as in  
classroom, meeting room, or lounge room situations where lights remain on, or where  
building external windows allow daylight into the room.  
Only in permanent installations with controlled lighting levels such as boardrooms, lecture  
theaters, or home theaters, should color management be considered. Color management  
provides fine color control adjustment to allow for more accurate color reproduction,  
should you require it.  
Proper color management can only be achieved under controlled and reproducible viewing  
conditions. You will need to use a colorimeter (color light meter), and provide a set of  
suitable source images to measure color reproduction. These tools are not provided with  
the projector, however, your projector supplier should be able to provide you with suitable  
guidance, or even an experienced professional installer.  
The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you  
select each color, you can independently adjust its range and saturation according to your  
preference.  
If you have purchased a test disc which contains various color test patterns and can be  
used to test the color presentation on monitors, TVs, projectors, etc, you can project any  
image from the disc on the screen and enter the 3D Color Management menu to make  
adjustments.  
To adjust the settings:

For example, if you select Red and set its  
value at 0, only the saturation of pure red  
will be affected.  
Saturation is the amount of that color in a video picture. Lower settings produce less saturated colors; a  
setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be  
overpowering and unrealistic.

Maintenance  
Care of the projector  
Your projector needs little maintenance. The only thing you need to do on a regular basis  
is to keep the lens and case clean.  
Never remove any parts of the projector except the lamp. Contact your dealer if other  
parts need replacing.  
Cleaning the lens  
Clean the lens whenever you notice dirt or dust on the surface. Please be sure to turn off  
the projector, unplug the power cable and let it cool down completely before cleaning the  
lens.  
Use a canister of compressed air to remove dust.  
If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens  
cleaner and gently wipe the lens surface.  
Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile  
solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or  
maintaining prolonged contact with rubber or vinyl materials may result in damage to  
the projector surface and cabinet material.  
Cleaning the projector case  
Before you clean the case, turn the projector off using the proper shutdown procedure as  
described in "Shutting down the projector" on page 36 and unplug the power cord.  
To remove dirt or dust, wipe the case with a soft, lint-free cloth.  
To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH  
detergent. Then wipe the case.  
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.  
Storing the projector  
If you need to store the projector for an extended time, please follow the instructions  
below:  
Make sure the temperature and humidity of the storage area are within the  
recommended range for the projector. Please refer to "Specifications" on page 55 or  
consult your dealer about the range.  
Retract the adjuster feet.  
Remove the battery from the remote control.  
Pack the projector in its original packing or equivalent.

Extending lamp life  
The projection lamp is a consumable item that normally can last up to 3000-4000 hours  
with proper usage. To keep the lamp life as long as possible, you can do the following  
settings via the OSD menu.  
Setting Lamp Mode  
Using Economic mode reduces system noise and power consumption by 20%. Using  
SmartEco ImageCare/SmartEco LampCare mode reduces system noise and power  
consumption by up to 70%, which adjusts image brightness dynamically. If the Economic,  
SmartEco ImageCare or SmartEco LampCare mode is selected, the light output  
will be reduced and result in darker projected pictures.

Replacing the lamp  
To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before  
changing the lamp.  
To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the  
lamp.  
To reduce the risk of injuries to fingers and damage to internal components, use caution when removing  
lamp glass that has shattered into sharp pieces.  
To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do not  
touch the empty lamp compartment when the lamp is removed.  
This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a  
proper manner.  
To assure optimal performance from the projector, it is recommended that you purchase a qualified  
projector lamp for lamp replacement.  
If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make  
sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes  
caused by fractured lamp.  
Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety  
glasses, goggles or face shield and wear protective clothing such as gloves.  
1.  
Turn the power off and disconnect the projector from the power outlet. If the lamp  
is hot, avoid burns by waiting for approximately 45 minutes until the lamp has  
cooled.  
2.  
Loosen the screw(s) that secures the lamp  
cover on the side of the projector until the  
lamp cover loosens.  
3.  
Remove the lamp cover from the projector.  
1
Do not turn the power on with the lamp cover  
removed.  
Do not insert your fingers between the lamp and the

Use the handle to slowly pull the lamp out of  
the projector.  
Pulling it too quickly may cause the lamp to break and  
scatter broken glass in the projector.  
Do not place the lamp in locations where water might  
splash on it, children can reach it, or near flammable  
materials.  
Do not insert your hands into the projector after the lamp  
is removed. If you touch the optical components inside, it  
could cause color unevenness and distortion of the  
projected images.

The dimensions are based on the BenQ wall mount (P/N: 5J.J4R10.001).  
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.  
The dimensions supplied are offered as a guide only and may differ depending on several factors relating to  
any specific installation.  
The dimensions are based on the projector being configured with zero keystone correction.  
The dimensions assume that the wall mount arm is positioned 90° from the bottom case of projector and  
screen surface.
