Unpacking the Projector
After unpacking the projector, make sure you have all the parts shown 
below:
Save all packaging in case you need to ship the projector. Always use 
the original packaging (or the equivalent) when you need to send the 
projector to another location.
If you are moving the projector by hand, use a carrying case (such as 
the optional cases available from EPSON). See page 7 for more 
information about cases.

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 VGA-to-component video cable. You can 
purchase this from EPSON; see page 7. 

To connect two computers to the projector at the same time, you 
need a DVI/analog interface cable. You can purchase this from 
EPSON; see page 7.

Some older PowerBooks and Macintosh desktop models may 
need the Macintosh adapter set shown on page 89 (available from 
EPSON; see page 7). Older iMac systems may need a special 
adapter to provide a VGA output port; see your computer dealer. 

Some systems may need an additional cable to use the remote 
control as a wireless mouse. If your Macintosh doesn’t have a USB 
port, you’ll need a Macintosh mouse cable. If your PC doesn’t 
have a USB or PS/2 port, you’ll need a PC serial mouse cable. See 
your projector dealer to obtain the correct cable.

To take advantage of the projector’s Digital Visual Interface, you 
need a DVI cable, and your computer must be capable of 
producing video signals in DVI format (for details, see page 93). 
You can purchase this cable from EPSON; see page 7.

To receive an audio signal, you may need a stereo mini-jack cable, 
available from most electronics dealers.

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

							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, approximately 
2.85 to 41 feet from the screen.

Make sure there is plenty of space for ventilation around and 
under the projector.

Make sure the projector is within 10 feet of a grounded 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 it toward the screen squarely.
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. note
It’s easier to position the 
projector when the screen is 
directly in front of the room. 
However, if you need to place 
it off-center, you can use the 
keystone correction feature to 
maintain a square image. See 
page 27 for more 
information.

							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 square shape, but you can correct the 
distortion by pressing the 
Keystone button as described in the next 
chapter. 
If you place the projector level with the bottom of the screen, the 
image will be square 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 
square, 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 
projector’s left side. You can 
purchase this from EPSON; 
see “Optional Accessories” on 
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 
Computer2/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 and you can’t connect the cable, you 
may need to use the Macintosh desktop adapter as shown on 
page 89 (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 control your 
computer and click through slideshow-style presentations, such as 
PowerPoint, from up to 30 feet away (for details, see page 41). This 
gives you more flexibility in delivering your presentation, since you 
won’t need to stand near your computer. 
The USB cable also provides audio support. If your presentation 
includes sound, you can play it through the projector’s speakers by 
connecting the USB cable.
1. Locate the cable you need, depending on whether your laptop has 
a round PS/2 mouse port or a flat USB mouse port. 
2. Connect one end of the cable to the projector’s   USB or 
Mouse port. 
3. Connect the other end of the cable to the external mouse port or 
USB port on your laptop.
4. If necessary, configure your laptop to work with an external 
mouse. 
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
If you’re using a PowerBook 
that has a round mouse port, 
you’ll need a Macintosh 
mouse cable. If you have a 
PC laptop with a serial 
mouse port, you’ll need a 
serial mouse cable. See your 
projector dealer to obtain the 
correct cable.
On a PowerBook or iBook, 
USB audio support is 
available for Mac OS 9.0 
and 9.1 only.

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 or better 
sound quality, you can connect a stereo, mini-jack audio cable (not 
included). 
1. Connect one end of the audio cable to the 
Audio1 jack on the 
projector.
  
2. Connect the other end of the audio cable to your laptop’s 
headphone jack or   audio-out jack. (Jack locations vary; see 
your computer manual if you’re not sure which jack to use.)
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
If you connected the USB 
cable, you may not need a 
separate audio cable to 
amplify audio from your 
computer.
