[. . . ] Your serial number is located under the name plate label on the right side of your MultiSync MT830/1030 . Record it here: CAUTION TO PREVENT SHOCK, DO NOT OPEN THE CABINET. This symbol warns the user that uninsulated voltage within the unit may be sufficient to cause electrical shock. Therefore, it is dangerous to make any kind of contact with any part inside of the unit. [. . . ] Ensure that the projector is square to the screen. (A) Top view screen (B) Side view 4. Move the projector left or right to center the image horizontally on the screen. To center the image vertically (B), lift the front edge of the projector and press the buttons on the front of the projector, just above the feet, to release the one-touch tilt feet. (There is approximately 10. 5° of up and down adjustment for the front of the projector. If a trapezoidal distortion appears on the screen, use the KEYSTONE button on the remote control or select Keystone from the menu to correct the distortion. If necessary, adjust the front or rear feet so that the lens surface is parallel to the screen. If you use the projector with the screen tilted, the picture will be distorted. Increase or reduce the size of the projected image by pressing the "Zoom" (+) or (­) buttons on the remote control or top of the cabinet.

If the projector falls to the ground, you can be injured and the projector severely damaged. · Do not use the LCD projector where temperatures vary greatly. The projector must be used at temperatures between 32°F (0°C) and 104°F (40°C). If the projector goes blank after a period of inactivity, it may be caused by a screen saver installed on the computer you've connected to the projector. When using a Macintosh with the MT830/1030, set the DIP switches of the supplied pin adapter according to your resolution. · When using with a Macintosh, XGA/VGA/SVGA is recommended if your Macintosh supports this mode. · When using with a Macintosh PowerBook, output may not be set to 1024 768 unless "mirroring" is off on your PowerBook. Refer to owner's manual supplied with your Macintosh computer for mirroring. NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub 15pin connector.
