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  
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.

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 www.lamprecycle.org.  
Use only BenQ's Ceiling Mount Kit for  
mounting the projector and ensure it is  
securely installed.  
20. This apparatus must be earthed.

Obtaining a preferred projected image size  
The distance from the projector lens to the screen, the zoom setting, and the video format  
each factors in the projected image size.  
For example, if you are using an 120-inch screen, the recommended projection distance is  
4755 mm and the vertical offset is 91mm or 183 mm.  
If your measured projection distance is 6.0 m (6000 mm), the closest match in the "Distance  
from screen (mm)" column is 5943 mm. Looking across this row shows that a 150'' (about  
3.8 m) screen is required.

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 projector has two built-in mono speakers 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 speakers.  
The built-in speaker 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 "Connecting audio" on page 16 for details.  
•
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.

2.  
3.  
Presentation mode: Is designed for presentations. The brightness is emphasized in this  
mode to match PC and notebook coloring.  
sRGB mode: Maximizes the purity of RGB colors to provide true-to-life images  
regardless of brightness setting. It is most suitable for viewing photos taken with an  
sRGB compatible and properly calibrated camera, and for viewing PC graphic and  
drawing applications such as AutoCAD.  
4.  
5.  
Cinema mode: Is appropriate for playing colorful movies, video clips from digital  
cameras or DVs through the PC input for best viewing in a blackened (little light)  
environment.  
User 1/User 2 mode: Recalls the settings customized based on the current available  
picture modes. See "Setting the User 1/User 2 mode" on page 27 for details.  
Setting the User 1/User 2 mode

Adjusting Contrast  
The higher the value, the greater the contrast. Use this  
to set the peak white level after you have previously  
adjusted the Brightness setting to suit your selected  
input and viewing environment.  
0
+30  
-30  
Adjusting Color  
Lower setting produces less saturated colors. If the setting is too high, colors on the image  
will be overpowering, which makes the image unrealistic.  
Adjusting Tint  
The higher the value, the more reddish the picture becomes. The lower the value, the more  
greenish the picture becomes.  
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.  
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 displays.

/
to select its range. Increase in the range will  
include colors consisted of more proportions of its two adjacent colors.  
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  
Yellow  
GREEN  
RED  
picture will be selected. Increasing its range  
will include red close to yellow and red close  
to magenta.

Every adjustment made will reflect to the  
image immediately.  
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.

device. If the connected devices have active audio output, you will still hear the audio even  
though the image is frozen onscreen.  
Hiding the image  
In order to draw the audience's full attention to the presenter, you can use BLANK on the  
projector or remote control to hide the screen image. The word “BLANK” appears in the  
corner of the screen while the image is hidden. When this function is activated with an audio  
input connected, the audio can still be heard.  
You can set the blank time in the SYSTEM SETUP: Basic > Operation Settings > Blank  
Timer menu to let the projector return the image automatically after a period of time when  
there is no action taken on the blank screen. The length of time can be set from 5 to 30  
minutes in 5-minute increments.  
If the preset time spans are not suitable for your presentation, select Disable.  
No matter Blank Timer is activated or not, you can press most of the keys on the projector  
or remote control to restore the picture.  
Do not block the projection lens from projecting as this could cause the blocking object to  
become heated and deformed or even cause a fire.  
Locking control keys  
With the control keys on the projector locked, you can prevent your projector settings from  
being changed accidentally (by children, for example). When the Panel Key Lock is on, no  
control keys on the projector will operate except  
POWER.  
Go to the SYSTEM SETUP: Basic > Panel Key Lock menu, and select On by pressing  
on the projector or remote control. A confirmation message displays.  
Highlight Yes and press MODE/ENTER to confirm.

Operating in a high altitude environment  
We recommend you use the High Altitude Mode when your environment is between 1500 m  
–3000 m above sea level, and ambient temperature is between 0°C–35°C.  
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient  
temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode  
on under such a condition.

Operation under "High Altitude Mode" may cause a higher decibel operating noise level  
because of increased fan speed necessary to improve overall system cooling and  
performance.  
If you use this projector under other extreme conditions excluding the above, it may display  
auto shut-down symptoms, which is designed to protect your projector from over-heating.  
In cases like this, you should switch to High Altitude mode to solve these symptoms.  
However, this is not to state that this projector can operate under any and all harsh or  
extreme conditions.  
Creating your own startup screen (only for MX501/  
MX501-V)  
In addition to selecting the projector preset startup screen from among BenQ logo, Black or  
Blue screen, you can make your own startup screen that is a picture projected from your  
computer or video source.  
To create your own startup screen, project the picture you want to use as your startup screen  
from either a computer or video source. The rest steps are as follows.

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.  
•
•
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 33 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 52 or  
consult your dealer about the range.
