Setting-up Methods The projector supports the following two different projection methods, allowing you to choose the best method for displaying your images. After setting up the projector, refer to the User's Guide for details on turning on the power and adjusting settings such as the screen size. ("Basic Operations" in User's Guide) Before setting up the projector, be sure to first read the separate Safety Instructions/World-Wide Warranty Terms. Front projection Rear projection using a translucent screen When using rear projection using a translucent screen, set the "Rear Proj.

[. . . ] ("Advanced" menu in User's Guide) 4 Continued 3 Connecting to a Video Source 5 When connecting the projector to other video sources, take the following precautions. Turn off the power for both the projector and the video source before connecting them. If the power for either device is on at the time of connection, damage may result. Check the shapes of the cable connectors and the device ports before making the connections. If you try to force a connector to fit a device port with a different shape or number of terminals, a malfunction or damage to the connector or port may result. If you select either port when image signals are being input from both the Video port and the S-Video port, unevenness may appear. This manual and the separate User's Guide use the term "video equipment" to refer to devices such as the following that are equipped with video output ports. Video cassette decks Game equipment DVD players Video cameras RGB video equipment Laser disc players The cable that is used to connect the video equipment to the projector varies according to the format of the video signals that are output from the video equipment. Some types of video equipment can also output video signals in several different formats. If you try to force a connector to fit a device port with a different shape or number of terminals, damage to the connector or port may result. The projector cannot be connected to some types of computer, or projection of images may not be possible even if actual connection is possible. Make sure that the computer you intend to use satisfies the conditions given below. Check that the computer has a port such as an "RGB port", "monitor port" or "CRT port" which can output image signals. If the computer has a built-in monitor, or if using a laptop computer, it may not be possible to connect the computer to the projector, or alternatively you may need to purchase a separate external output port. Refer to the documentation for your computer under a heading such as "Connecting an external monitor" or similar for further details. Condition 2: The display resolution and frequency of the computer must be listed in the "List of Supported Monitor Displays". ("Appendices: List of Supported Monitor Displays" in User's Guide) Some computers allow you to change the output resolution, so if necessary, change the resolution to one that matches a setting in the "List of Supported Monitor Displays", while referring to the documentation provided with the computer. You may need to purchase a separate adapter depending on the shape of the computer's port. [. . . ] You may need to purchase a separate adapter depending on the shape of the computer's port. Refer to the documentation provided with the computer for further details. If the computer and projector are too far away from each other for the accessory computer cable to reach, use the optional VGA-HD15 PC cable. [. . . ]
