Getting Ready Setting Up the Projector Locate the projector on a desk, table, or stand that is firm and level. Make sure to allow sufficient space around the sides and back of the projector for proper ventilation.  The following illustrations show how the projector should be oriented for optimum projection relative to the screen. Viewed from Above Viewed from the Side (XJ-A130/XJ-A135/XJ-A140/XJ-A145) Screen Screen Make sure the projector is at a right angle to the screen. The center of the projector's lens should be aligned with the horizontal center of the screen. Viewed from the Side (XJ-A230/XJ-A235/XJ-A240/XJ-A245) Screen Position the projector so the lens side is at the edge of the table, etc. Important!  You can place the projector on a surface that is angled up to 30 degrees upwards or downwards during use. Never locate the projector on a surface that is angled more than 30 degrees, or angled at all to the left or right. Such conditions can shorten lamp life, and also creates the risk of malfunction.  The projector's auto keystone correction range is 0 to +30 degrees. If the surface you are projecting onto is angled downwards from horizontal, use manual keystone correction (page E-22) to correct the image.  Turn on the "Option Settings 2  High Altitude" setting on the setup menu when using the projector in a high altitude (1,500 to 3,000 meters (5,000 to 10,000 feet) above sea level) area where air is thin. For details, see the User's Guide on the CD-ROM that comes with the projector. NOTE  The projector can be configured for projection from the back of a screen. For details, see the User's Guide on the CD-ROM that comes with the projector. E-14
