E-16 This section describes how to set up your LT75Z projector and how to connect video and audio sources. Setting up Your Projector Your LT75Z Projector is simple to set up and use. But before you get started, you must first: 1. Determine the image size. 2. Set up a screen or select a non-glossy white wall onto which you can project your image. Ensure that the power cable and any other cables connecting to video sources are disconnected before moving the projector. When moving the projector or when it is not in use, cover the lens with the lens cap. Selecting a Location The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 30 (0.8 m) measured diagonally when the projector is roughly 4 feet (1.3m) from the wall or screen. The largest the image can be is 200 (5.1 m) when the projector is about 30 feet (9.2m) from the wall or screen. Screen and Projection Distance The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation. 2.

Contact your dealer for more information. * Do not attempt to install the projector yourself. •Only use your projector on a solid, level surface. If the projector falls to the ground, you can be injured and the projector severely damaged. •Do not use the projector where temperatures vary greatly. The projector must be used at temperatures between 41°F (5°C) and 95°F (35°C). •Do not expose the projector to moisture, dust, or smoke. This will harm the screen image. •Ensure that you have adequate ventilation around your projector so heat can dissipate. Do not cover the vents on the side or the front of the projec- tor. Reflecting the Image Using a mirror to reflect your projector’s image enables you to enjoy a much larger image. Con- tact your NEC dealer if you need a mirror. If you’re using a mirror and your image is inverted, use the “Menu” and “Select” buttons on your pro- jector cabinet or buttons on your remote con- trol to correct the orientation. (See page E-33.)
