12-volt DC output

The 3.5mm mini-jack trigger provides a 12-volt DC output. It provides a constant output while the projector is on. It has numerous uses. For example, if you connect your projection screen to the 12-volt DC output with the cable that came with your screen, when you turn on the projector the screen will move down; when you turn the projector off, the screen will return to the storage position. To use the 12-volt DC output, you must first remove the safety plug.

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 general guidelines:

•Position the projector on a flat surface at a right angle to the screen. The projector must be at least 4.9 feet (1.49m) from the projection screen.

•Position the projector within 10 feet (3m) of your power source and within 6 feet (1.8m) of your video device (unless you purchase extension cables). To ensure adequate cable access, do not place the projector within 6 inches (.15m) of a wall or other object.

•To turn the image upside down, see “Ceiling” on page 24. We recommend using an 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 top illustration to the right shows three projected image sizes. For more information about image sizes at different distances, see “Projected Image Size” on page 27.

•The image offset is 127.3% when the projector is in 16:9 mode. This means that if you have an image 10’ high, the bottom of the image will be 2.73’ above the center of the lens.

•See “Connecting a video device” on page 11 for additional information on 16:9 mode.

Projector and Device Connector Guide

The following illustration and table should help you find the connectors to use and obtain the best resolution possible from your input devices, such as computers, standard VCRs, DVD players (progressive and interlaced), HDTV sources, TV and satellite tuners, camcorders, video games (progressive and interlaced), and laser disc players.

Computer connections

Computer connections involve attaching the VGA and USB ends of the provided computer cable to a computer and connecting the other end (M1 cable end) to the Computer In input on the projector. The USB part of the computer cable allows you to advance slides in a PowerPoint™ presentation via a remote control. See page 6 for computer/projector setup information.
