First-time projector use with Windows 98The first time you connect a computer running Windows 98 to the projector, 
the computer recognizes the projector as “new hardware” and the Add 
New Hardware Wizard appears. Follow these instructions to use the Wiz-
ard to load the correct driver (which was installed with your Windows 
operating system).
If you are running Windows 2000, Windows ME, or Window XP, skip these 
steps and go to “Adjusting the image” on page 12.aClick Next to begin searching for the driver.bMake sure “Search for the best driver” is selected, then click Next.cUncheck any checked boxes, then click Next. Windows automatically 
locates the driver. If this driver has been removed, reload the driver using 
your Windows operating system CD.dWhen Windows finds the driver, you are ready to install it. Click Next.

puter cable
For Windows 98:

appears again. Drivers must be installed to use the USB functionality.

The first time it detects a USB Human Interface Device (for the key-
board). 
The second 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.

connector on the video device. Plug the other yellow connector into the yel-
low Video 2 connector on the projector. 
Plug a white connector into the left audio out connector on the video device 
and plug a red connector into the right audio out connector on the video 
device. Plug the remaining white connector into the left audio in connector 
on the projector, and plug the red connector into the right audio in connec-
tor on the projector.
Connect the black power cable to the connector on the back of the projector 
and to your electrical outlet. 
NOTE: Always use the power cable that shipped with the projector.Optional video connectionsIf the video device uses a round, four-prong S-video connector, plug an 
S-video cable (sold separately) into the S-video connector on the video 
device and into the S-Video 1 connector on the projector. Use the A/V 
cable’s audio connectors as described directly above (the yellow connectors 
on the A/V cable are not used).

Shutting down the projectorThe projector automatically blanks the screen after no active source is 
detected for 30 minutes. This blank 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. The Interactive Display on the projector indicates 
the shutdown status.
Screen Save
You can make the blank screen appear after five minutes by turning on 
Screen Save in the Settings>System menu. See page 33. There are six time 
options for the Screen Save feature. They range from five minutes to 30 min-
utes with five minute intervals.
Pow e r  S av e
The projector also has a Power Save feature that automatically turns the 
lamp off after no signals are detected for 5 minutes. After 3 additional min-
utes with no signal, the projector powers down. If an active signal is 
received before the projector powers down, the image is displayed. You 
must press the Pow e r button to display an image after 30 minutes have 
passed. When Power Save is enabled, Screen Save is disabled. See page 33.
Turning off the projector
To turn off the projector, press the Powe r button and verify that you want to 
turn the projector off by pressing the Powe r button again within 3 seconds. 
You can cancel the shutdown by not pressing the Pow e r button a second 
time. The lamp turns off and the LED blinks green for 1 minute while the 
fans continue to run to cool the lamp. When the lamp has cooled, the LED 
lights green and the fans stop. Unplug the power cable to completely power 
off the projector.
Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section 
(page 25). If it does not, troubleshoot the setup. The Interactive Display and 
LED on top of the projector indicate 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.
