6 Important safety instructions

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.
Hg – Lamp contains mercury. Manage in accordance with local disposal laws. See www.lamprecycle.org.

There is 5% tolerance among these numbers due to optical component variations. BenQ recommends that if you intend to permanently install the projector, you should physically test the projection size and distance using the actual projector 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.

It is recommended to adjust focus 15 minutes after powering on due to the slight shifting of the lens from temperature changing.

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. 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

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 your preference by pressing /. The contrast level of the primary color you select will be affected. Every adjustment made will reflect to the image immediately.
