ENGLISH-17 ENGLISH MAINTENANCE MAINTENANCE Lamp HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE Contact your dealer before replacing the lamp. For the optional lamp, see the item “Optional Parts” of the Table 12. Before replacing the lamp, switch power OFF, remove the power cord from the power outlet, and wait approximately 45 minutes until the lamp has cooled. The lamp may explode if handled at high temperatures. Lamp Life Projector lamps have a finite life. The image will become darker, and hues will become weaker, after a lamp has been used for a long period of time. Replace the lamp if the LAMP indicator is red, or the CHANGE THE LAMP message appears when the projector is switched ON. See Table 9 of P.20 and Table 10 of P.21. •The LAMP indicator is also red when the lamp unit reaches high temperature. Before replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again. If the LAMP indicator is still red, replace the lamp.NOTE WARNINGAmercury lamp used in this LCD projector is made of glass and has high internal pressure. The mercury lamp can burst with a big noise due to deterioration resulting from a shock, crack and passage of time, and can end its service life in unlit condition. Lamps also have a considerably different service life and can sometimes end up in burst or turn to unlit condition soon after use. Furthermore, when the lamp is blown up, glass fragments can get scattered around the lamp house and some gas containing mercury inside the lamp can leak out of the projector’s air vent. • Handle the lamp with utmost care as it can burst during use if subjected to a shock or impact or if scratched or cracked. • Probability for the burst will increase if the lamp is used for extended period of time or used exceeding the period of replacement. You are advised to follow instructions for lamp replacement as soon as they are given (Refer to Table 9 of Page 20, Table 10 of Page 21). Avoid any reuse of an old lamp (used lamp) since such reuse can result in burst. • In case the lamp gets blown up in a short period of time after use, some electrical failures or troubles other than the lamp itself may be suspected as causes. Under such circumstances, consult the store where you purchased it or a service company. • Should the lamp burst (accompanied by a big bursting noise), perform ventilation sufficiently, and exercise maximum caution not to inhale any gas out of the projector’s air vent or not to let it enter your eyes or mouth. • Should the lamp burst (accompanied by a big bursting noise), make absolutely sure to unplug the power cord from the outlet and ask the store where you bought the lamp for immediate replacement. You should not engage in cleanup or replacement of the lamp by yourself since scattered glass fragments can damage the inside of projector or can result in personal injury when you handle it. • When you dispose of any used lamps, be sure to observe and follow local ordinances and regulations of the area or district where they are subjected to disposal. Generally speaking, the lamps are treated similarly as glasses and bottles in most cases, but there are areas or districts where lamps are classified as a separate collection, and so be sure to use caution. • Never use the lamp in a state where the lamp cover is removed.

Switch the projector power supply OFF, and remove the power cord from the power outlet. 2. Clean the air filter with a vacuum cleaner. Other Maintenance Maintenance Inside the Equipment For safety reasons, ensure that the equipment is cleaned and checked by the dealer once every two years. Maintaining the equipment by yourself is dangerous. Cleaning the Lens Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hands. Cleaning the Cabinet and Remote control transmitter Gently wipe with a soft cloth. If dirt and stains etc. are not easily removed, use a soft cloth dampened with water, or water and a neutral detergent, and wipe dry with a soft, dry cloth. CAUTION• Switch power OFF and remove the power cord from the power outlet before beginning maintenance work. Please read the separate “Safety Guide” thoroughly to ensure that maintenance is performed correctly. • Do not use detergents or chemicals other than those noted above (e.g. benzene or thinners). • Do not use cleaning sprays. • Do not rub with hard materials, or tap the equipment. CAUTION• Switch power OFF and remove the power cord from the power outlet before beginning maintenance work. Please read the separate “Safety Guide” thoroughly to ensure that maintenance is performed correctly. • Replace the air filter if contamination cannot be removed, or if it is damaged. Contact your dealer in such case. For the optional air filter, see the item “Option Parts” of the Table 12. • Do not use the equipment with the air filter removed. • When the air filter is clogged with dust etc. the power supply is switched OFF automatically to prevent the temperature rising inside the projector. Replacing the Air Filter Replace the air filter if contamination cannot be removed, or if it is damaged. 1. Remove the filter cover. 2. Remove the old filter. 3. Set the new filter and the filter cover. •When this projector is brought into a warm room from a cold outdoor, condensation can take place on the projection lens and mirror inside, blurring the screen and reducing your eyesight, but do not worry. The condensation will disappear and the screen will return to a normal condition no sooner than the projector acclimates to the surrounding temperature.NOTE EW 1.
