Connecting to a Macintosh Desktop Computer
To connect the projector to your desktop Macintosh, you need to use 
the computer cable. If you’ll be using the remote control as a wireless 
mouse, you need to connect a mouse cable. If you’ll be using audio 
through the projector’s speakers, you need to connect an audio cable.
Connecting the Computer Cable
Before you start, turn off the projector and computer.
1. Disconnect the monitor cable from the video (monitor) port on 
the back of the Macintosh.
2. Connect one end of the computer cable to the projector’s 
Computer port. 
3. Connect the other end of the computer cable to the video 
(monitor) port on the Macintosh. 
4. Tighten the screws on the connectors.
If you don’t need to make any other connections, you can plug in and 
turn on your equipment; see page 23 for instructions.

the USB mouse cable.
1. Connect one end of the USB mouse cable to the  USB 
Mouse port on the projector.
2. Connect the other end to the USB port on your Macintosh.
If you don’t need to make any other connections, you can plug in and

Audio In port on the 
projector.
 
2. Connect the other end of the audio cable to the audio-out port on 
your Macintosh. 
note
Your Macintosh must be 
using Macintosh OS 8.51 or 
later for USB support.
See page 34 for instructions 
on using the remote control as 
a wireless mouse.
note
If you need additional 
volume (in a large 
auditorium, for example), 
you can also connect external 
speakers or a public address 
system; see page 21 for 
instructions.

turn on your equipment; see page 23 for instructions.
Connecting to Video Sources
You can connect a DVD player, VCR, camcorder, laser disc player, 
digital camera, or any other compatible video source to your projector. 
You can connect one video source and a computer at the same time, 
and easily switch between them. The projector supports HDTV, 
NTSC, PAL, and SECAM formats, and automatically detects the one 
you’re using.
Connecting the RCA A/V Video Cable
Before you start, make sure the projector and your VCR or other 
video source are turned off.
1. Connect the yellow plug on one end of the A/V cable to the 
projector’s yellow 
Video jack. 
2. Connect the other yellow plug to the video-out jack on your video 
source.
3. Connect the red and white plugs on the A/V cable to the 
projector’s 
Audio L (white) and R (red) jacks.
4. Connect the red and white plugs at the other end of the cable to 
the corresponding audio output jacks on your video source.
note
You can’t use the projector 
with a cable TV-style 
F connector.

Connecting an S-Video Cable
If your video source has an S-Video jack (as shown with an S-Video 
plug to the right), you can use it to project a higher quality video 
image. However, you’ll need an S-Video cable, which may be included 
with your video source or may be purchased from an electronics or 
video store.
Before you start, make sure the projector and your VCR or other 
video source are turned off.
1. Insert one end of the S-Video cable into the projector’s 
S-Video 
connector. 
2. Insert the other end into the S-Video output port of your video 
source.
3. Connect the red and white plugs on the A/V cable to the 
projector’s 
Audio L (white) and R (red) jacks.
4. Connect the red and white plugs at the other end of the cable to 
the corresponding audio output jacks on your video source.
Connecting a Component Video Cable
You can connect a component video cable to project images from a 
DVD player or HDTV video source. You’ll need the RCA A/V cable 
(included with your projector) and a component video cable 
(optional; available from EPSON as described on page 6).

5. Select the correct settings for your component video source in the 
projector’s Video menu (as described on page 42):

If you connected the projector to a DVD player, select 
YCbCr as the Input Signal setting.

If you connected an HDTV source or if your DVD player

If your projected image seems 
distorted, you may need to 
change your aspect ratio. 
Generally, 
16.9 (for wide 
screen) is the correct setting. 
						

							Setting Up the Projector21
Connecting to External Speakers or a PA 
System
 
The projector’s speaker is loud enough for most small- or medium-size 
rooms. For large rooms or maximum volume, you can connect the 
projector to external speakers or a public address (PA) system. 
You’ll need an RCA-to-3.5 mm stereo audio cable, which may be 
included with your sound system or may be purchased from an 
electronics store. 
Before you start, make sure the projector and speakers or PA system 
are turned off.
1. Connect the cable’s 3.5 mm stereo miniplug to the projector’s 
Audio Out jack.
2. Connect the RCA plugs to the speaker or PA system. Insert the 
cable’s red plug into the Audio R jack and the white plug into the 
Audio L jack.
note
The projector’s internal 
speaker is disabled when you 
use an external audio system.

Using the Projector23
Using the Projector
Once you’ve connected the projector to your computer or other 
equipment (as described in Chapter 1), you’re ready to turn on the 
projector, adjust the image, and give your presentation. This chapter 
covers the following:

Turning on the projector and other equipment

Adjusting your image

Using the remote control

Controlling audio and video

Highlighting your presentation

Shutting down the projector and other equipment
Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1. Then plug in and turn 
on your equipment, as described below. 
Follow these steps to plug in and turn on your equipment:
1. If you’re projecting video, 
first plug in and turn on 
your VCR, DVD player, or 
other video source. (If 
you’re projecting from a 
computer, go to step 2.)
2. To turn on the projector, 
first connect one end of the power cord to the projector’s power 
inlet on its left side. 
note
If you have more than one 
source connected, you may 
have to switch to the one you 
want to use, as described on 
page 25. 
						

							24Using the Projector3. Connect the other end to a grounded electrical outlet. 
The 
Power light on the projector turns orange, indicating that 
the projector is receiving power and is in sleep mode, but is not 
yet turned on.
4. Remove the lens cap. 
5. Press the red 
Power button on top of the projector. (You can 
also turn on the projector using the remote control, but you must 
turn on the remote control first; see page 32.)
The 
Power light flashes green and then stays on. You see a 
blue screen with the message 
No Signal displayed.
6. If you’re projecting images from a computer, turn on your 
computer. In a few moments, you should see your computer 
display projected. (If a projected image fails to appear, see the next 
section for help.)
7. If you’re projecting video, press the 
Play button. (If a projected 
image fails to appear, see the next section for help.)
Once you see your image, turn to page 29 for instructions on focusing 
and making other image adjustments. 
When you’re done with your presentation, shut down the projector as 
described on page 38. Shutting down the projector correctly prevents 
premature lamp failure and possible damage to the projector from 
overheating. 
warning
Never look into the lens when 
the lamp is on. This can 
damage your eyes, and is 
especially dangerous for 
children.

What To Do If You See a Blank Screen
If you see a blank screen or a blue screen with the message No Signal 
after turning on your computer or video source, do one of the 
following:

Make sure the cables are connected correctly, as described in 
Chapter 1.

Make sure the Power light is green and not flashing and the 
lens cap is off. 

If you’ve connected more than one input source, you may need to 
press the 
Source button on top of the projector or the 
Computer, Video, or S-Video button on the remote control to 
select the source you want to use. (Allow a few seconds for the 
projector to sync up after pressing the button.)

Try restarting your computer.

If you still don’t see an image and you’re using a PowerBook, see 
page 26 or  27 for additional steps. If you’re using a PC laptop, 
see page 28.
