Positioning the Projector

If the projector isn't already installed in the room you're using,

you'll probably want to place it on a table in front of the screen.

This lets you stand in the front of the room, face the audience,

and remain close enough to the equipment to be able to control

it. Try to leave as much space as possible between the projector

and the screen to get a good-size image.

Use the figure below to help you determine placement. Image

size increases with distance, but can vary depending on how you

position the zoom ring and whether you've adjusted the image

with other settings.

Distance from screen

Also keep these considerations in mind:

❏ Place the projector on a sturdy, level surface.

❏ Make sure there is plenty of space for ventilation around

and under the projector. Do not set the projector on top of

anything that could block the vents under the projector.

❏ Make sure the projector is within 10 feet (3 meters) of a

grounded electrical outlet or extension cord.

Ideally, you should place the projector directly in front of the

center of the screen, facing it toward the screen squarely. The

base of the lens should be at about the level of the bottom of the

screen.

Projector

If you place the projector below screen level, you'll have to tilt it

up by extending the front adjustable foot. This causes the image

to become "keystone" shaped, but you can correct the

distortion. (See "Adjusting the Image Shape" on page 6.)

Turning On and Off the Projector

Turn on any connected computer or video equipment before

starting the projector so it can automatically detect and display

the image source. If you turn on the projector first or have

multiple pieces of connected equipment, you may have to select

the image source manually (see page 5).

Follow these steps to turn on the projector:

1. Open the A/V mute slide (lens cover).

2. Plug one end of the power cable into the projector, and the

other end into an electrical outlet.
