For Windows 98:
If you connected the USB cable, the Add New Hardware Wizard 
appears again. Drivers must be installed to use the USB functionality. 
The Wizard launches three times. 
The first time it detects a USB Composite Device. 
The second time a USB Human Interface Device (for the keyboard). 
The third time it detects a USB Human Interface Device (for the 
mouse). 
For Windows 2000, Windows ME, and Windows XP:
The USB drivers are automatically installed.

Connecting a video deviceYou can connect VCRs, DVD players, camcorders, digital cameras, video 
games, HDTV receivers, and TV tuners to the projector. There is also an 
audio input. You can connect the audio directly to the projector to get sound 
from the onboard speaker, or you can connect it to your stereo’s receiver to 
get sound from your own speakers.
Before connecting your projector, you should decide which aspect ratio you 
want to use. Aspect ratio is the ratio of the image width to image height. TV 
screens are usually 4:3, which is the default for this projector. HDTV and 
most DVDs are 16:9. If you’re projecting onto a screen, the size/shape of the 
screen may answer this question for you. If you are projecting onto a blank 
wall, you don’t have the screen size restriction. What you plan to project 
will also help you choose between 4:3 and 16:9. Most regular TV shows are 
4:3, while most movies are 16:9.
If you select 4:3 and play TV, the image will fill the screen. If you select 16:9 
and play HDTV, the image will fill the screen. However, if you select 4:3 and 
play a 16:9 DVD, the image may be compressed horizontally or have black 
bars along the top and bottom. If you select 16:9 and play regular TV, the 
image may be stretched horizontally or have black bars along the sides. You 
can make this selection later using the onscreen menus (page 30), but for 
now you just need to know which format you’ll use most often.
You can connect the projector to most video devices that can output video. 
You cannot directly connect the coaxial cable that enters your house from a 
cable or satellite company, the signal must pass through a tuner first. Exam-
ples of tuners are digital cable boxes, VCRs, digital video recorders, and sat-
ellite TV boxes. Basically, any device that can change channels is considered 
a tuner.

Video connectionsThe next step is to figure out what type of connectors/output the equip-
ment you want to connect has. If there is more than one output, select the 
one with the highest quality. Component video has the best quality, fol-
lowed by S-video, then composite video. 
If you are connecting the projector to HDTV, the projector ’s computer con-
nector should be used.
Keep in mind that HDTV and progressive sources can only be handled 
through the projector ’s VGA connector. The optional Component to S-video 
adapter does not function with progressive sources. With progressive 
sources, the Component video connector requires the optional Component 
to  V ESA a dap te r.  Here is a list of possible input signals and the connectors they should be 
connected to on the projector

Video device connectionsComposite video connectionPlug the included video cable’s yellow connector into the video-out connec-
tor on your video device. Plug the other yellow connector into the yellow 
Video In connector on the projector. Plug the included audio adapter’s 
white connector into the left audio out connector on your video device; plug 
the audio adapter’s red connector into the right audio out connector on the 
video device. Plug the included audio cable into the black connector on the 
audio adapter. Plug the other end of the audio cable into the blue Audio In 
connector on the projector. 
Keep in mind that video output from composite connections are not as high 
quality as S-video or component.S-video connectionIf your video device uses a round, four-prong S-video connector, plug an S-
video cable (sold separately) into the S-video connector on your video 
device and into the S-video connector on the projector. Use the audio cable 
and the audio adapter as described above.
Keep in mind that S-video delivers higher quality video output than com-
posite, but not as high quality video output as component.

Component video connectionIf your video device has component connectors, use a Component to S-
video adapter or the Component to VESA adapter (available from a third-
party vendor) for HD and progressive sources. Plug the component cable 
into the video device. Plug the other end of the component cable into the 
adapter and plug the adapter into the projector’s S-video (for S-video) or 
Computer in (for VESA) connector. Use the audio adapter as described on 
the previous page.
Component connection offers the highest quality video output.VGA connectionIf your video device has a 15-pin VGA output, plug one end of the included 
computer cable to the VGA connector on your video source. This connector 
may be labeled “To Monitor” on the video source. Plug the other end of the 
cable into the Computer In connector on the projector.
Use the audio adapter as described on the previous page.
Connect the power cord to the Pow e r connector on the side of the projector 
and to your electrical outlet.
NOTE: Always use the power cord that shipped with the projector.

Displaying videoRemove the lens cap.
Toggle the Pow e r switch on the side of the projector to the On position.
The LED flashes green and the fans start to run. When the lamp comes on, 
the start-up screen is displayed and the LED is steady green. It can take a 
minute for the image to achieve full brightness. 
? No start up screen? Get help on page 18.
Plug in and turn on your video device.
The video device’s image should appear on the projection screen. If it 
doesn’t, press the Video button on the keypad. 
? No image? Get help on page 21.Adjusting the imageAdjust the height of the projector by pressing the release button to extend 
the foot. 
Rotate the leveling foot at the rear of the projector, if necessary. 
Position the projector the desired distance from the screen at a 90 degree 
angle to the screen.

Adjust the volume on the keypad or remote.
Adjust the Contrast, Brightness, Color, Tint, or Aspect Ratio in the Picture 
menu. See page 30 for help with the menus and these adjustments.
For Aspect Ratio, keep in mind that DVD players must be configured for 
16:9 in order to view the highest quality image. For more information 
regarding Aspect Ratio, see page 11.

Shutting down the projectorThe projector automatically displays a black screen after no active source is 
detected for 30 minutes. This black screen helps preserve the life of the pro-
jector. The image returns when an active source is detected or a remote or 
keypad button is pressed.Screen SaveYou can make the black screen appear after a preset number of minutes by 
turning on the Screen Save feature in the Settings>System menu. See 
page 33.Pow e r  S av eThe projector also has a Power Save feature that automatically turns the 
lamp off after no active sources are detected and no user interaction with 
the projector is performed for 20 minutes. By default, this feature is off. See 
page 33.Turning off the projectorYou can turn the projector off simply by toggling the power switch to the off 
position.
You can also press the remote’s Power button to place the projector in the 
Off state while it is running. When the Power button is pressed twice (once 
to start the power-down process and a second time to verify that you want 
to power the projector off), the lamp turns off and the LED blinks green for 
one (1) minute while the fans continue to run to cool the lamp. While the 
LED is blinking green, the projector does not accept any keypad and remote 
control input.
When the lamp has cooled, the LED lights solid green and the fans slow 
down to minimal speed. To turn off the projector, toggle the power switch to 
the off position. 
NOTE: Once the projector has been toggled off, you must wait for one (1) 
minute before turning the projector on again. This allows the lamp to prop-
erly cool. However, if the remote was used to power the projector to the Off 
state you do not need to wait one minute to turn it on again.
Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section. If it 
does not, troubleshoot the setup. 
The LED on top of the projector indicates the state of the projector and can 
help you troubleshoot. 
The following tables show common problems. In some cases, more than one 
possible solution is provided. Try the solutions in the order they are pre-
sented. When the problem is solved, you can skip the additional solutions.
