Introduction10

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.

Installing dust filter covers

Be sure to install the dust filter covers before using the projector.

1. Complete the installation of dust filter covers on the two sides of the projector as the illustration.

2. Turn on the projector, then press “MENU/EXIT”, go to the SYSTEM SETUP: Basic > Operation Settings > Fan Speed and select High.

3. Clean the dust filters periodically.

The dust filters should be cleaned or replaced periodically (suggest after every 500 hours or 3 months of use). If they are not cleaned periodically, they can become clogged with dust and prevent the projector from being ventilated properly. This can cause over heating and damage the projector. If the projector is used in a dusty environment, be sure to cleaned or replaced the dust filters more frequently.

Positioning your projector

Choosing a location

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment.

Your projector is designed to be installed in one of four possible installation locations:

1. Front Table

Select this location with the projector placed near the floor in front of the screen. This is the most common way to position the projector for quick setup and portability.

2. Front Ceiling

Select this location with the projector suspended upsidedown from the ceiling in front of the screen.

Purchase the BenQ Projector Ceiling Mounting Kit from your dealer to mount your projector on the ceiling.

Set Front Ceiling in the SYSTEM SETUP: Basic > Projector Installation menu after you turn the projector on.

3. Rear Table

Select this location with the projector placed near the floor behind the screen.

Note that a special rear projection screen is required.

Set Rear Table in the SYSTEM SETUP: Basic > Projector Installation menu after you turn the projector on.

4. Rear Ceiling

Select this location with the projector suspended upsidedown from the ceiling behind the screen.

Note that a special rear projection screen and the BenQ Projector Ceiling Mounting Kit are required for this installation location.

Set Rear Ceiling in the SYSTEM SETUP: Basic > Projector Installation menu after you turn the projector on.

You can also use Quick Install key on the remote control to select projectors location.

Positioning your projector 15

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size.

For example, if you are using a 40-inch screen, the projection distance is 437 mm and with a vertical offset of 67 mm.

If your measured projection distance is 1.0 m (1000 mm), the closest match in the

"Projection distance (mm)" column is 908 mm. Looking across this row shows that a 80''

(about 2.0 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.
