[. . . ] Such conditions create the risk of malfunction of and damage to the projector. Avoid areas subject to temperature extremes (operating temperature range is 5°C to 35°C (41°F to 95°F)). Never place heavy objects on the projector or climb on top of the projector. Never insert or allow foreign objects to drop into the projector. Never place a vase or any other container of water on top of the projector. Whenever setting the projector down or performing any operation that involves moving or reorienting it, take care that you do not pinch your fingers under the projector. Never leave a dead battery inside the remote controller for a long time. A dead battery can leak, which leads to malfunction of and damage to the remote controller. Clean with a soft, dry cloth. When very dirty, use a soft cloth that has been dampened in a weak solution of water and a mild neutral detergent. Wring all excess water from the cloth before wiping. Never use thinner, benzine, or any other volatile agent to clean the projector. Doing so can remove its markings and cause staining of the case. Missing Screen Dots Though this projector is manufactured using the most advanced digital technology available today, some of the dots on the screen may be missing. This is normal, and does not indicate malfunction. Never subject the projector to strong impact while it is projecting. If the projector is accidentally subjected to strong impact, the projection image will momentarily go blank. The image will reappear after some time, but it may be the wrong color or it may be accompanied by an error message. If the projected image is the wrong color, re-select the current input source. If this does not return the projected image to its proper color, use the procedure under "To turn off the projector" on page E-15 to turn projector power off and then back on again. If the image reappears with an error message, correct the problem in accordance with the indicator explanations under "Error Indicators and Warning Messages" in the User's Guide on the CD-ROM that comes with the projector. E-8 Operating Precautions Keystone Correction and Image Quality Performing keystone correction causes the image to be compressed before it is projected. This can result distortion of the image or a loss of image quality. If this happens, change orientation of the projector and/or screen so it conforms as much as possible to the illustration under "Setting Up the Projector" on page E-11. If image quality is the highest priority, turn off auto keystone correction and position the projector so it is pointed straight at the screen. Even if your projector is still within the warranty period, you will be charged for repair if a problem is due to running the projector non-stop for very long periods (like 24 hours) or if the projector was set up and used without following the "Setup Precautions" on page E-12 of this manual. Precaution when Handling the Projector after Use The projector's exhaust vents and the area around the vents become very hot during operation, and will still be hot immediately after turning off the projector. Because of this, you should hold the sides of the projector as shown in the illustration whenever moving it. Stowing the Projector in the Carrying Bag Make sure the projector is no longer warm before stowing it in the carrying bag. Cleaning the Projector Periodically clean the projector exterior, lens, intake vents, exhaust vents, and airflow vents on a regular basis. Dust and dirt tend to collect around the intake vents. Because of this, you should use a vacuum cleaner to clean away accumulated dust and dirt periodically. Continued use of the projector after dust has accumulated around the intake vents can cause overheating of internal components and lead to malfunction. Certain operating conditions also can cause dirt and dust to accumulate around the projector's exhaust vents and airflow vents.
