Positioning the projector

To determine where to position the projector, consider the size and shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. Here are some guidelines:

Position the projector on a flat surface at a right angle to the screen. The pro- jector must be at least 4.9 feet (1.5m) from the projection screen.

For safety reasons, position the projector within 10 feet (3m) of your power source (running extension cables may introduce a trip hazard). To ensure ade- quate cable access, do not place the projector within 6 inches (.15m) of a wall or other object.

If you are installing the projector on the ceiling, refer to the installation guide that comes with the Ceiling Mount Kit for more information. To turn the image upside down, see “Ceiling” on page 24. We recommend using an InFo- cus authorized ceiling mount.

Position the projector the desired distance from the screen. The distance from the lens of the projector to the screen, the zoom setting, and the video format determine the size of the projected image.

The image offset is 136%. This means that if you have an image 10’ high, the bottom of the image will be 3.6’ above the center of the lens.
