E­2 Important Safeguards These safety instructions are to ensure the long life of your projector and to prevent fire and shock. Please read them carefully and heed all warnings. CAUTION Do not unplug the power cable from the wall outlet under any one of the following circumstances. Doing so can cause damage to the projector: * While the Hour Glass icon appears. * While the message "Please wait a little." appears. This message will be displayed after the projector is turned off. * Immediately after the power cable is plugged into the wall outlet (the POWER indicator has not changed to a steady amber glow). * Immediately after the cooling fan stops working (The cooling fan continues to work for 30 seconds after the projector is turned off with the POWER button). * While the POWER and the STATUS indicators are alternately flashing. Installation 1. For best results, use your projector in a darkened room. 2. Place the projector on a flat, level surface in a dry area away from dust and moisture. 3. Do not place your projector in direct sunlight, near heaters or heat radiating appliances. 4. Exposure to direct sunlight, smoke or steam can harm internal components. 5. Handle your projector carefully. Dropping or jarring can damage internal components. 6. Do not place heavy objects on top of the projector. 7. If you wish to have the projector installed on the ceiling: a. Do not attempt to install the projector yourself. b. The projector must be installed by qualified technicians in order to ensure proper operation and reduce the risk of bodily injury. c. In addition, the ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes. d. Please consult your dealer for more information. CAUTION Do not put the projector on its side when the lamp is turned on. Doing so may cause damage to the projector. CAUTION Avoid displaying stationary images for a prolonged period of time. Doing so can result in these images being temporarily sustained on the surface of the LCD panel. If this should happen, continue to use your projector. The static background from previous images will disappear. Power Supply 1. The projector is designed to operate on a power supply of 100-120 or 200-240 V 50/60 Hz AC. Ensure that your power supply fits this requirement before attempting to use your projector. 2. Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire. 3. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet. Cleaning 1. Unplug the projector before cleaning. 2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong detergents or solvents such as alcohol or thinner. 3. Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens. E­3 Lamp Replacement · To replace the lamp, follow all instructions provided on page E-33. · Be sure to replace the lamp when the message "The lamp has reached the end of its usable life. Please replace the lamp."appears. If you continue to use the lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your NEC dealer for lamp replacement. · Allow a minimum of 30 seconds to elapse after turning off the projector. Then disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp. Fire and Shock Precautions 1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 3 inches (10 cm) of space between your projector and a wall. 2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified NEC service personnel. 3. Do not place any liquids on top of your projector. · Do not look into the lens while the projector is on. Serious damage to your eyes could result. · Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can cause unpredictable outcome such as fire or injury to the eyes. · Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to melting of the cap and possibly burning your hands due to the heat emitted from the light output. E­4 TABLE OF CONTENTS 1.
