Using A Tabletop Or Cart1. Place your projector on a flat level surface at the optimal

distance from the screen or wall so you realize the sizeimage you want. (Avoid having bright room lighting orsun light directly on the screen or wall where you'll beprojecting the image.)

2. Connect the power cable, remove the lens cap and turn theprojector on. (If no input signal is available, the projectorwill display a background image.)

3. Ensure that the projector is square to the screen.

4. Move the projector left or right to center the imagehorizontally on the screen. (A)

5. To center the image vertically (B), lift the front edge of theprojector and press the buttons on the front of the projec-tor, just above the feet, to release the one-touch tilt feet.(There is approximately 5.0˚ of up and down adjustmentfor the front of the projector.

6. To fine tune the image's position vertically on the screen,rotate each front foot, and rear feet if necessory.

Note: Adjust feet so that lens surface is parallel to the screen. Ifyou use the projector with the screen tilted, the picture will bedistorted.

7. Adjust the size of the image using the zoom ring lever onthe lens.

Connecting Your PC Or MacintoshComputerConnecting your PC or Macintosh computer to yourMultiSync LT100 (XGA) Projector will enable you to projectyour computer's screen image for an impressive presentation.All of these following display standards are supported:

To connect to a PC, Macintosh or computer equipped with anXGA/SVGA/VGA adapter or compatible graphics adapter,simply:

1. Turn off the power to your projector and computer.

2. If your PC does not support XGA/SVGA/VGA you willneed to install an XGA/SVGA/VGA graphics board.Consult your computer's owner's manual for your XGA/SVGA/VGA configuration. If you need to install a newboard, see the manual that comes with your new graphicsboard for installation instructions.

3. Use the signal cable that's supplied to connect your PC orMacintosh computer to the projector. For Macintosh, usethe supplied pin adapter to connect to your computer'svideo port.

4. Turn on the projector and the computer.

5. If the projector goes blank after a period of inactivity, itmay be caused by a screen saver installed on the com-puter you've connected to the projector.

2. Turn the main unit so that the bottom is up.

3. Loosen the lamp cover retaining screw.

4. Slide the lamp cover in the direction of the arrow and remove it.

CAUTION: Do not use a lamp other than the NEC replacementlamp.Order this from your NEC dealer using your projector's modelnumber.

5. Loosen the three retaining screws for the lamp housing.

(There is an interlock on the lamp housing to prevent the risk ofelectrical shock. Do not attempt to circumvent this interlock.)

6. Holding the handle, pull the lamp housing forward and take itoff.

7. Install the new lamp housing and fasten with the three screws.
