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 on the projector or  
remote control.  
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.

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,  
shorten the projector's life span and  
darken the image.  
If the ventilation holes are seriously  
obstructed, overheating inside the  
projector may result in a fire.  
15. 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.

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.  
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.  
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.  
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.

For example, if you are using an 120-inch screen, the recommended projection distance is  
3608 mm and the vertical offset is 162 mm.  
If your measured projection distance is 6.0 m (6000 mm), the closest match in the  
"Distance from screen (mm)" column is 6013 mm. Looking across this row shows that a  
200'' (about 5.1 m) screen is required.  
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.

on page 46 for details.  
Connecting video source devices  
You need only connect the projector to a video source device using just one of the  
connecting methods, however each provides a different level of video quality. The method  
you choose will most likely depend upon the availability of matching terminals on both the  
projector and the video source device as described below:

Connecting audio  
The projector has built-in mono speaker(s) which are designed to provide basic audio  
functionality accompanying data presentations for business purposes only. They are not  
designed for, nor intended for stereo audio reproduction use as might be expected in  
home theater or home cinema applications. Any stereo audio input (if provided), is mixed  
into a common mono audio output through the projector speaker(s).  
The built-in speaker(s) will be muted when the AUDIO OUT jack is connected.  
The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See  
If the selected video image is not displayed after the projector is turned on and the correct video source  
has been selected, check that the video source device is turned on and operating correctly. Also check  
that the signal cables have been connected correctly.  
Playing sound through the projector  
You can make use of the projector (mixed mono) speaker(s) in your presentations, and  
also connect separate amplified speakers to the AUDIO OUT socket of the projector.  
If you have a separate sound system, you will most likely want to connect the audio output  
of your Video source device to that sound system, instead of to the mono audio projector.  
You can also use a microphone to output the sound through the projector speaker(s).  
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)  
menus. See "Audio Settings" on page 45 for details.

The selected input signal determines which sound will be played by the projector speaker(s), and which  
sound will be output from the projector when AUDIO OUT is connected. If you select the COMPUTER  
1/Y Pb Pr 1 signal, the projector can play the sound received from AUDIO IN 1/MIC. If you select the  
COMPUTER 2/Y Pb Pr 2 signal, the projector can play the sound received from AUDIO IN 2/MIC.  
The projector can play sound if the connected RJ45 cable or USB cable carries audio signal. There is no need  
to connect the audio cable when the USB Display or Network Display source is selected.  
About the microphone input  
If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the  
projector.  
You can use a wireless microphone as long as a wireless module is attached to the  
projector’s microphone input jack and it works well with the associated devices. To  
ensure a quality use of the wireless microphone, it is recommended that your  
microphone conforms to the specifications listed in the table below.

To make the microphone input available when the projector is in standby mode, turn  
on the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.  
If the microphone is not working, check the volume setting and cable connection.  
You might get feedback noise from the microphone when you are too close to the  
speaker(s) of the projector. Move the microphone away from the speaker(s) of the  
projector. The greater volume you require, the greater distance you need to be away  
from the speaker(s) to prevent the noise.

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.  
Selecting a Color Temperature  
The options available for color temperature* settings vary according to the signal type  
selected.  
1.  
2.  
3.  
Cool: Makes images appear bluish white.  
Normal: Maintains normal colorings for white.  
Warm: Makes images appear reddish white.  
*About color temperatures:  
There are many different shades that are considered to be "white" for various purposes.  
One of the common methods of representing white color is known as the “color  
temperature”. A white color with a low color temperature appears to be reddish white. A  
white color with a high color temperature appears to have more blue in it.

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:  
1.  
2.  
Go to the PICTURE menu and highlight 3D Color Management.  
Press MODE/ENTER on the projector or remote control and the 3D Color  
Management page appears.

Please refer to the illustration to the right  
for how the colors relate to each other.  
For example, if you select Red and set its  
range at 0, only pure red in the projected  
picture will be selected. Increasing its range  
will include red close to yellow and red close  
to magenta.

Press  
to highlight Saturation and adjust  
its values to your preference by pressing  
. Every adjustment made will reflect to  
the image immediately.  
/
BLUE  
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.  
6.  
Press

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 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 56 or  
consult your dealer about the range.
