English Getting Ready Setup Precautions Note that operating conditions greatly affects the performance of the projector. Make sure you only operate the projector in the type of environment described below.  Use a conveniently located power outlet that you can reach easily when you need to unplug the projector.  Do not place any objects within the area indicated by the dashed line in the illustration below. Keep all items at least 30cm (11.8 inches) away from the intake and exhaust vents. Allow sufficient clearance and do not block intake and exhaust vents. Exhaust vents Intake vents Intake vents Intake vents 30cm (11.8 inches)  The vents become quite hot while the projector is in use. Never touch the vents with your hands. Also, the areas near the exhaust vents become quite hot. Never locate objects made of plastic or other heat-sensitive materials near or under the projector. Doing so creates the risk of deformation and discoloration of the object.  Avoid placing the projector on a surface that is unstable or prone to vibration. Never place the projector on top of a carpet, blanket, towel, or other soft material.  Do not locate the projector where it will be exposed to direct sunlight.  Avoid locations where there are large amounts of dust and moisture.  Keep the projector away from speakers, TVs, radios, and other devices that generate magnetism, as well as from heaters.  Over time, use of the projector can cause dust and dirt to build up in and around the fan's intake vents, which can lead to malfunction of the projector. Be sure to check the intake vents for dust build up each time before you use the projector. If you see dirt or dust in or around the intake vents, remove it by wiping with a cloth, etc.  When positioning the projector, make sure you do so in such a way that the intake vents do not become blocked. Blocked intake vents can shorten the life of the lamp.  Airflow from air conditioning equipment can blow the heat being exhausted from the area around the projector's lens in a way that causes heat ripples to appear in the projected image. If this happens, adjust the airflow of the air conditioning equipment or move the projector. E-15
