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.
