							Setting Up the Projector35
Connecting to Other Video Sources
You can connect a VCR, camcorder, laser disc player, DVD player, 
digital camera, or any other compatible video source to your projector.
The projector supports HDTV, NTSC, PAL, and SECAM video 
formats, and automatically detects and identifies the video format. 
However, you can specify that a single broadcast format be detected. 
(See page 65.) Note that the projector will then be able to detect only 
one type of video signal.
The projector can receive composite video, S-Video, or 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 cables supplied with the projector. For S-Video, use the S-Video 
cable supplied with your video device or obtain one from your 
computer or video equipment dealer. For component video, use the 
BNC-style cable that came with your video source. 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 
Computer2/Component Video port and the S-Video port 
share the same audio input. So if you have connected a video source to 
both interfaces, note that you can use audio from only one of them.

The projector is not 
compatible with 
cable TV-style 
F connectors.

Connecting RCA Cables
Before starting, make sure the projector and your VCR or other video 
source are turned off.
1. Connect the yellow RCA plug on one end of the RCA video cable 
to the projector’s 
Video port. Connect the other end of the cable 
to the video-out port of your video source. 
2. If you’ll be using audio, connect the RCA audio cable to the left 
and right Audio ports of the projector (insert the white plug into 
the 
L port and the red plug into the R port). Connect the plugs at 
the other end of the cable to the audio output ports of the video 
source.

Connecting S-Video or Component Video
Before starting, make sure the projector and your VCR or other video 
source are turned off.
1. For S-Video, insert one end of an S-Video cable into the 
projector’s 
S-Video connector. Insert the other end into the 
S-video-out port of your video source.
For component video, connect the three ends of a BNC 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.) Insert the opposite ends of 
the cable into the corresponding ports of your video source. If the 
image doesn’t display properly, you may need to change the BNC 
parameter in the projector’s Setting menu. See page 69. 
2. If you’ll be using audio, connect the RCA audio cable to the 
S-Audio and Audio2 ports of the projector. Connect the plugs at 
the other end of the cable to the audio output ports of the video 
source.

Using the Projector39
Using the Projector
Once you have connected your projector to your other equipment 
(as described in Chapter 1), you’re ready to turn it on, adjust the 
image, and give your presentation. This chapter covers the following:

Turning on the projector and other equipment

Adjusting the image

Using the remote control 

Zooming your image with the remote

Controlling the projector

Drawing on the screen

What to do when the lights flash

Using the on-screen help

Shutting down the projector
Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1. 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 more than one computer or video source is 
connected, you may have to switch to the desired source, as described 
on page 51.  
						

							40Using the Projector
Turning On the Projector
Follow these steps to 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 starts flashing orange and 
then stays 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 (or the remote 
control) to turn on the projector. (If you are using the remote, 
make sure it is turned on. See page 48 for more information.)
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, turn on your video source and 
press the 
Play button.

warning
Never look into the lens when 
the lamp is on. This can 
damage your eyes, and is 
especially dangerous for 
children. 
						

							Using the Projector41

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.)
These buttons switch the display between the video source(s) 
and the computer source(s).
If a projected image fails to appear, see the next section for help. 
Once you see your image, turn to page 44 for instructions on focusing 
and making other image adjustments. 
When you’re done with your presentation, shut down the projector as 
described on page 58. Shutting down the projector correctly prevents 
premature lamp failure and damage to the projector from overheating. 
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 conne cte d more t han 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.)

Try restarting your computer.

3. To display the entire desktop on both your projector screen and 
LCD screen, click the 
Arrange tab. (If you don’t see this tab, 
make sure it is not hidden by another window on your screen.)
4. Click 
Mirror Displays in the lower corner of the screen. One of 
the monitor icons automatically moves on top of the other.
If you’re using a PC laptop:

Press the function key that lets you display on an external 
monitor. It’s often identified with an icon such as   or 
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   or 
CRT/LCD 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.

							44Using the Projector
Sleep Mode
When the projector has not received any input signals for 30 minutes, 
it automatically turns off the projector lamp and enters “sleep mode.” 
In sleep mode, only a minimum amount of the projector’s circuitry 
remains on. This conserves electricity, cools the projector, and extends 
the life of the lamp. When you are ready to start projecting again, 
press the 
Power button. If you are done using the projector, unplug 
the power cord.
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 45 for more information.

If the image is too high or too low, you can reposition it. See 
page 46.

If the image isn’t square, see page 47.

If the image is flickering or “noisy,” see page 47. 
Focusing and Zooming Your Image
Rotate the focus ring to sharpen the image. 
note
When the projector is in sleep 
mode, the power light is 
orange. If necessary, you can 
disable sleep mode in the 
Setting menu. See page 69.
