Additional Components
Depending on how you plan to use the projector, you may need 
additional components:
■To receive an S-Video signal, you need an S-Video cable. (One is 
usually provided with your video device.)
■To receive a component video signal from a VCR or other video 
device, you need a D-sub, 15-pin, VGA to component video cable 
(available from EPSON; see page 7).
■To amplify your computer’s audio through the projector’s sound 
system, you need a computer audio cable (male-to-male 3.5-mm 
stereo miniplug cable). See your computer or electronics dealer to 
obtain this cable. 
■Some older PowerBooks and Macintosh desktop models may 
need the Macintosh adapter set shown on page 82 (available from 
EPSON; see page 7). Older iMac systems may need a special 
adapter to provide a VGA output port; see your computer dealer.

Setting Up the Projector
This chapter tells you how to set up the projector and connect it to a 
laptop computer or video source. If you need to connect the projector 
to a desktop or workstation computer, see Appendix A.
You’ll find instructions for the following in this chapter:
■Positioning the projector
■Connecting to a laptop computer
■Connecting to video sources 
						

							10Setting Up the Projector
Positioning the Projector
Before connecting the projector, you need to decide where to place it. 
The location you choose depends on the size of the room and what 
you are projecting.
■Place the projector on a sturdy, level surface, between 
2.9 and 34.4 feet from the screen.
■Make sure there is plenty of space for ventilation around and 
under the projector. Leave at least 8 inches between the projector 
and a wall.
■Make sure the projector is within 6 feet of an electrical outlet or 
extension cord and within 5 feet of your computer and/or video 
source. 
■Place the projector directly in front of the center of the screen, 
facing the screen squarely. Otherwise, your image will not be 
rectangular.
Most presenters find it convenient to place the projector in front of 
the audience, leaving as much space as possible between the projector 
and the screen to get a good-sized image. This lets the presenter stand 
in the front of the room, face the audience, and remain close enough 
to the equipment to be able to control it.
Use the figure below as a guideline to help you determine how far 
from the screen to place the projector. Image size generally increases 
with distance, but may vary depending on how you position the zoom 
ring and whether you have adjusted the image size with other settings. 
caution
Don’t hold or lift the 
projector by the lens, or 
you may damage it.
note
It’s 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’s 
much more difficult to aim 
the projector correctly at the 
screen and get a rectangular 
image. 
30.1 to 34.4 feet 5.9 to 6.8 feet 2.9 to 3.4 feet 
						

							Setting Up the Projector11
If you place the projector below the level of the screen, you’ll have to 
tilt it up by extending the feet as shown. Tilting the projector upward 
causes the image to lose its rectangular shape, but the Auto Keystone 
feature corrects the distortion automatically. If the image does not 
regain its rectangular shape, the Auto Keystone feature may have been 
disabled. To turn it on or for more information on keystone 
correction, see page 27.
If you place the projector level with the bottom of the screen, the 
image will be rectangular and you won’t have to adjust it. If you place 
the projector higher than the bottom of the screen, the image will still 
be rectangular, but you won’t be able to fill the whole screen with the 
image. 
note
After positioning the 
projector, you may want to 
connect a Kensington 
MicroSaver anti-theft device 
to the lock port on the back o
f 
the projector. You can 
purchase this from EPSON; 
see page 7. 
						

							12Setting Up the Projector
Connecting to a Laptop Computer
You can connect the PowerLite projector to any computer that has a 
standard video output (monitor) port, including PC notebook and 
laptop computers, Macintosh PowerBooks and iBooks, and hand-held 
devices.
Connecting the Computer Cable
Before you start, make sure your computer and the projector are 
turned off.
1. Connect one end of the computer cable to the projector’s 
Computer/Component Video port.
2. Connect the other end of the computer cable to your laptop’s 
video-out or monitor port.
If you’re using a PowerBook or iBook and you can’t connect the 
cable, you may need to use the Macintosh desktop adapter as 
shown on page 82 (available from EPSON; see page 7). 
3. Tighten the screws on the connectors.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 20 for instructions.
note
To connect to desktops and 
other computer systems, see 
Appendix A. If you have an 
iBook with an RCA video- 
out port, follow the 
instructions for connecting to 
a video device on page 16.
note
Laptop configurations vary. 
See your computer manual 
for the location of the ports 
needed to connect your 
projector. 
						

							Setting Up the Projector13
Connecting the Cable for Remote Mouse 
Control
Using the remote control as a wireless mouse lets you click through 
slideshow-style presentations, such as PowerPoint, from up to 20 feet 
away (for details, see page 34). This makes it easy to deliver your 
presentation, since you won’t need to stand near your computer. 
1. Locate the USB mouse cable and connect one end of the cable to 
the projector’s USB port.
2. Connect the other end of the cable to the external mouse port or 
USB port on your laptop, as shown.
3. If necessary, configure your laptop to work with an external 
mouse. 
						

							14Setting Up the Projector4. You can connect an external mouse to the USB Type A port or 
use the port as a USB hub to connect an external USB device, if 
you want.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 20 for instructions.
Amplifying Computer Audio
Your laptop probably has its own sound system; however, it may not 
be adequate for your presentation. If you need more volume, you can 
connect a computer audio cable to take advantage of the projector’s 
built-in amplifier and speaker. You can obtain a computer audio cable 
(3.5-mm stereo miniplug cable) from a computer or electronics dealer.
1. Connect one end of the audio cable to the 
Audio1 jack on the 
projector.
