ENGLISH - 42 Maintenance Care and Replacement JBefore cleaning the projector Switch off the projector and disconnect the mains plug from the mains socket. Unplug all the cables from the projector. JCleaning the outer surface of the projector Wipe off dirt and dust gently with a soft cloth. If it is difficult to remove the dirt, soak a cloth with water, wring the cloth well and then wipe the projector. Dry off the projector with dry cloth. Do not use petroleum benzine, thinner, any alcoholic solvent, kitchen detergents or chemical clothes. Failure to observe these may result in altered or damaged surface of the projector. JCleaning the front glass surface Wipe off dirt and dust gently with a lint-free cloth. Make sure no dirt or dust remains on the surface of the lens cover glass. It will be enlarged and projected onto a screen. JCleaning the air filter If the air filter is excessively dirty, the internal temperature of the projector increases and may cause malfunction. Clean the air filter regularly every 100 hours of usage. 1. Turn the projector upside down and place it gently on a soft cloth. 2. press the tab and slightly slide up the air filter to remove. 3. Vacuum dirt and dust from the air filter. Do not wash the air filter. 4. Place and slightly slide in the air filter in the air intake port to attach. Make sure the air filter clicks into the place. JReplacing the air filter The air filter should be replaced when cleaning is ineffective and when replacing lamp unit. A replacement air filter is provided with a replacement lamp unit (ET-LAB80). Contact an Authorised Service Centre for the optional air filter (TXFMZ01VKG7). Cleaning the projector NOTE: • Clean the front glass with special care. Giving a shock may cause serious damage. Tab Air filter NOTE: • Do not use the projector without attaching the air filter.
Care and Replacement ENGLISH - 43 Maintenance The lamp unit, ET-LAB80 is consumable and you must replace it regularly. It is recommended that a qualified technician carry the lamp unit replacement and consult with an Authorised Service Centre. JWhen to replace the Lamp unit When the lamp is consumed, the brightness may decrease over time. 3 000 hours of use is the replacing timing as rough guided, and that might be shortened by the usage conditions, characteristics of the lamp unit or environmental conditions. You can find the duration of usage time by checking LAMP RUNTIME in OPTION menu. JBefore replacing the lamp unit Contact an Authorised Service Centre to purchase a replacement lamp unit (ET-LAB80). Switch off the projector and disconnect the mains plug from the mains socket. Wait for more than 1 hour and make sure the lamp unit and the surroundings are cooled enough. Prepare a Phillips-head screwdriver. When the projector is mounted in the ceiling, do not work directly under the projector or put your face closer to the projector. Replacing the Lamp unit IndicationOn screen LAMP indicator Over 2 800 hoursDisplays “REPLACE LAMP” on the upper left of the screen for 30 seconds. Illuminates red. Over 3 000 hoursDisplays “REPLACE LAMP” on the upper left of the screen, and it will stay until you respond. Press any button to clear the screen. NOTE: • The guide times, 2 800 and 3 000 hours, are rough estimates based on certain conditions and is not a guaranteed time. • For more information about the lamp unit and its guaranteed time, see the instructions which is provided with the lamp unit. • Do not use a lamp unit over 3 000 hours. Failure to observe this may result in explosion of the lamp. NOTE: • Prior to replacing the lamp unit, allow it to cool down to prevent the risk of burns, damage and other hazards. • Do not attempt replacement with an unauthorised lamp unit. REPLACE LAMP
