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.
The projector supports HDTV, NTSC, PAL, and SECAM, and 
automatically detects the video format. (However, if you’re using a 
60-hertz PAL system, you’ll need to select 
PAL60 in the Video menu, 
as described on page 45.)
The projector can receive composite video, S-Video, and component 
video. You can connect the projector to one or more of these video 
sources at the same time. If all three are connected, the projector 
automatically selects S-Video as the video source. 
The type of cable you use depends on whether you have composite 
video, S-Video, or component video.

For composite video, use the RCA video cables included with the 
projector. 

For component video, use the BNC-style cable that came with 
your video device. 

For S-Video, use the S-Video cable supplied with your video 
device or obtain one from your electronics dealer. 
See the following illustration if you’re unsure of which type of 
connectors you have.
Follow the instructions below for your type of connection.

the projector’s 
Video jack. 
2. Connect the other end of the cable to the video-out jack on your 
video source.
3. Connect the RCA audio cable to the left and right Audio jacks on 
the projector (insert the white plug into the

Connecting S-Video 
If your video source has an S-Video jack, 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.
Before starting, make sure the projector and your DVD player or 
other video source are turned off.
1. Insert one end of an 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 RCA audio cable to the left and right 
S-Video/BNC 
audio jacks on the projector. (Match the red and white plugs to 
the red and white jacks.)
4. Connect the plugs at the other end of the cable to the audio 
output jacks on your video source.

you’ve connected a video 
source to both interfaces, you 
can use audio from only one 
of the sources.

Connecting Component Video Cables
If your video source has component video connectors, you can use 
them to project a higher quality video image. However, you’ll need a 
BNC video cable, which may be included with your video source, or 
may be purchased.
Before starting, make sure the projector and your DVD player or 
other video device are turned off.
1. Connect the three ends of the component video cable into the 
projector’s 
R, G, and B ports. (Don’t connect the cables to the 
projector’s 
H/C Sync or VSync ports.) 
2. Insert the opposite ends of the cable into the corresponding ports 
on your video source. If the image doesn’t display properly, you 
may need to change the 
BNC option in the projector’s Setting 
menu (see page 52).  
3. Connect the RCA audio cable to the left and right 
S-Video/BNC 
audio jacks on the projector. (Match the red and white plugs to 
the red and white jacks.)
4. Connect the plugs at the other end of the cable to the audio 
output jacks on your video source.

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. 
Although you can operate the projector without it, the remote control 
lets you use additional features. See Chapter 3 for instructions on 
using the remote. This chapter covers the following:

Turning on the projector and other equipment

Adjusting the image

Controlling the projector

Shutting down the projector

							20Using the Projector
Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1 or Appendix A. Then 
turn on your projector, as described below, followed by any 
equipment you’ve connected to it. You can turn on your computer 
and video equipment in any order, but if you have more than one 
computer or video source connected, you may have to switch to the 
desired source as described on page 27. 
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Connect one end of the power cord to the projector’s power inlet. 
2. Connect the other end to a grounded electrical outlet. 
The power light on the projector’s control panel turns orange, 
indicating that the projector is receiving power but not yet turned 
on.  
3. Remove the lens cap.

4. Press the red Power button on top of the projector. 
The power light flashes green as the projector warms up, and the 
projection lamp comes on in about 30 seconds. The power light 
stays green, and you may see a blue screen with the message 
No 
Signal 
displayed. This is normal. 
5. Do one of the following:

Turn on or restart your computer. In a few moments, you 
should see your computer display projected.
(Windows only: If you see a New Hardware Found message 
saying that it has found a plug-and-play monitor, click 
Cancel.) 

If you’re projecting a video, press the Play button on your 
video source.
If a projected image fails to appear, see the next section for help. 
Once you see your image, turn to page 24 for instructions on focusing 
and making other image adjustments. 
When you’re done with your presentation, shut down the projector as 
described on page 28. Shutting down the projector correctly prevents 
premature lamp failure and possible damage to the projector from 
overheating.

after turning on your computer or video source, do one of the 
following:

Make sure the cables are connected correctly, as described on 
page 12 (for laptops) or in Appendix A (for other systems).

Make sure the power light is green and not flashing and the lens 
cover is off. 

Try restarting your computer.

If you’ve connected more than one computer and/or video source, 
you may need to press the 
Computer or Video button on top of 
the projector to select the correct source. (Allow a few seconds for 
the projector to sync up after pressing the button.)
If you’re using a PowerBook:
You may need to set up your system to display on the projector screen 
as well as the LCD screen. Follow these steps:
1. From the Apple menu, select

If this option isn’t available, you may need to select one of the 
Simulscan resolution settings:
1. Click the 
Monitor icon. 
2. Select a 
Simulscan resolution as shown. (Allow a few seconds for 
the projector to sync up after making the selection.)
If you’re using a PC laptop:

Press the function key that lets you display on an external 
monitor. It’s often labelled with an icon such as   but it may 
also be labelled 
CRT/LCD. You may have to hold down the Fn key 
while pressing it. Check your laptop’s manual or online help for 
details. 
On most systems, the   key lets you toggle between the LCD 
screen and the projector, or display on both at the same time. 
Allow a few seconds for the projector to sync up after pressing it. 

Depending on your computer’s video card, you might need to use 
the Display utility in the Control Panel to make sure that both the 
LCD screen and external monitor port are enabled. See your 
computer’s documentation or online help for details.

Adjusting the Image
Once you see your image, you’ll need to make certain adjustments:

To focus or zoom your image, see below. 

If only part of a computer image is displayed, you may need to 
press the 
Resize button. See page 25 for more information.

If the image is too high or too low, you can reposition it. See
