8. Once the lamp is fully inserted, tighten its screws.
9. Replace the lamp cover and tighten its screw securely. (The 
projector won’t come on if the lamp cover is loose.)
Transporting the Projector
The projector contains many glass and precision parts. If you need to 
transport it, please follow these packing guidelines to prevent damage 
to the projector: 

When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials, placing plenty of cushioning 
around the projector.

When transporting the projector for business use, first put it in a 
carrying case (such as an optional EPSON case), then pack it in a 
firm box, using cushioning around the case. 

When you are hand-carrying the projector, be sure to store it in a 
carrying case (such as an optional EPSON case).

If you want to store the remote control inside the projector’s 
carrying case, be sure to turn it off using the switch on its side. 
This prevents the batteries from discharging if something presses 
against one of the buttons.
note
EPSON shall not be liable 
for any damages incurred 
during transportation.

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.
If you’re using a PowerBook:
1. From the Apple menu, select

If this option isn’t available, select one of the other compatible 
video formats listed on page 90. 

Windows:
Right-click the desktop, select 
Properties, click the Settings 
tab, and select a different resolution. 

Macintosh:
On the Apple menu, choose 
Control Panels, then click 
Monitors and Sound. Select a different resolution. 

You also may need to modify existing presentation files if you 
created them for a different resolution. See your software 
documentation for specific information.
The image isn’t square, but trapezoid-shaped.

Make sure the projector isn’t placed off to one side of the screen, 
at an angle, or the image won’t be square. Place the projector 
directly in front of the center of the screen, facing the screen 
squarely.

If you’ve tilted the projector upward by extending the legs, the 
image will be broader at the top. Hold down the 
+ or – side of the 
Keystone button on top of the projector until the image is 
square.
