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 fitting 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.

Mounting the projector

If you intend to mount your projector, we strongly recommend that you use a proper fitting 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.
• T ake 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.

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 contr olled and r epr oducible 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. Go to the Picture menu and highlight 3D Color Management.
2. Press MODE/ENTER and the 3D Color Management page displays.
3. Highlight Primary color and press ◄/► to select a color from among Red, Green, Blue, Cyan, Magenta and Yellow.
4. Press to highlight Hue and press ◄/► 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 picture will be selected. Increasing its range will include red close to yellow and red close to magenta.
5. Press to highlight Saturation and adjust its values to your preference by pressing /. 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.
6. Press to highlight Gain and adjust its values to y our pr ef er ence by pr ess ing ◄/►. The contrast level of the primary color you select will be affected. Every adjustment made will reflect to the image immediately.

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 clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other parts need replacing.

Cleaning the Projector Mirror

Remove the dust with a "Bellows/Lens Blower" readily available from camera shops to prevent scratching the mirror with subsequently wiped.

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 52 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 75 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.

Light information

Getting to know the light hour

When the projector is in operation, the duration (in hours) of light usage is automatically calculated by the built-in timer. The method of calculating the equivalent light hour is as follows:
1. Light Usage Time = (x+y+z+a) hours, if
Time used in Normal mode = x hours Time used in Eco mode = y hours Time used in SmartEco mode = z hours Time used in LampSave mode = a hours
2. Equivalent Light Source Hour = α hours
α = x(A’ / X) + y(A’ / Y) + z(A’ / Z) + a(A’ / A), if X = light life spec of Normal mode Y = light life spec of Eco mode Z = light life spec of SmartEco mode A = light life spec of LampSave mode A’ is the longest light life spec amoung X, Y, Z, A
For time used in each light mode shown in OSD menu:
Time used is accumulated and rounded down to an integer in Hours.
When time used is less than 1 hour, it shows 0 hours.
When you calculate Equivalent Light Sour ce Hour manual ly, it will probably have de viatio n fr om the value shown in OSD menu si nce pr ojector sy st em calculates Time used for each Light Mode in Minutes then rounds down to an integer in hours shown in OSD.
See "Setting Light Mode as Economic or SmartEco" below for more information on Economic mode.
To obtain the light hour information:
1. Press MENU/EXIT and then press ◄/► until the SYSTEM SETUP: Advanced
menu is highlighted.
2. Press to highlight Light Settings and press MODE/ENTER. The Light
Settings page displays.
3. You will see the Light Timer information displaying on the menu.
4. To leave the menu, press MENU/EXIT.
You can also get the light hour information on the INFORMATION menu.
Maintenance67

Extending light life

The projection light is a consumable item. To keep the light life as long as possible, you can do the following settings via the OSD menu.
Setting Light Mode as Economic or SmartEco
Using Economic mode reduces system noise and power consumption by 15%. Using SmartEco mode reduces system noise and light power consumption by up to 30%. If the Economic or SmartEco mode is selected, the light output will be reduced and result in
darker projected pictures. Setting the projector in Economic or SmartEco mode also extends the light operation
life. To set Economic or SmartEco mode, go into the SYSTEM SETUP: Advanced >
Light Settings > Light Mode menu and pr ess / until y our desired mode is selected.
