Never let children look into the lens when it is on. Never open any cover on the projector, except the lamp and
filter covers. Dangerous electrical voltages inside the projector can severely injure you. Except as specifically
explained in the User’s Guide or this Supplement, do not attempt to service this product yourself. Refer all

This appendix describes how to connect the projector to your
desktop computer and turn everything on. The projector must
be connected to a computer or a video source such as a VCR,
camcorder, digital camera, DVD player, or laser disc player
before it can project any images. You may also want to set up
the projector for one or more of the following:
■Connect the mouse cable to use the remote control as a
wireless mouse. Except for some laptops, this disables your
computer’s mouse. You use the remote control’s pointer to
control the screen cursor.
■Provide audio for one or both image sources. The audio
source can be the computer, video source, or another device
such as a stereo.
■Connect to an external speaker or PA system to amplify the
audio (see your User’s Guide for instructions).
Positioning the Projector
Before you can set up the projector, you need to decide where
to place it. Keep the following in mind:
Place the projector on a sturdy, level surface.
■
Make sure the projector is within 10 feet of a grounded
■
electrical outlet or extension cord.
Place the computer and/or video source within 5 feet of the
■
projector.
Make sure the projector is at right angles to the screen.
■
Otherwise, your image will be distorted.

note
It is easier to position the
projector when the screen is
directly in front of the room.
If the screen is placed
diagonally in a corner, it is
much more difficult to
position the projector
perpendicular to the screen
and get a non-distorted
image.
Most presenters find it convenient to place the projector (and
computer) in the front of the room. With this arrangement, the
projector is placed close to the screen. You need to raise the
front of the projector (by extending the legs) in order to
position the image high enough on the screen. Then you can
use the projector’s keystone control to correct the distortion
caused by tilting up the front of the projector.
The distance between the projector and the screen determines
the actual image size. Use the general guidelines in the table
below to determine the proper distance.
The following illustrations identify all the interface ports on the
back and side of the projector; you may want to refer to them as
you connect your computer or other equipment to the
projector.

If you need maximum
volume (in a large
auditorium, for example),
you can also connect
external speakers or a public

Connecting the Cable for Remote Mouse
Control
Using the remote control as a wireless mouse gives you more
flexibility. You can deliver your presentation from anywhere in
the room and interact with the audience. You don’t need to
stand near your computer or near the projector.
You’ll use different cables and different ports on the projector,
depending on whether your computer has a round PS/2 mouse
port or a flat USB mouse port.

If you can’t connect the projector’s computer cable to your
Macintosh, you may need to use a Macintosh adapter
(available from Apple).
■Remove the small cover on the
Macintosh adapter and set its DIP
switches according to the resolution
you want to use (such as 16-inch
mode). See your Macintosh
documentation for instructions.
