You should keep the lens clean because any dirt or stains may appear on the screen. You will also need to clean the air filter attached at the bottom of the projector periodically because a clogged air filter prevents proper ventilation that is necessary to cool the projector and prevents it from overheating. If any parts need to be replaced, contact your dealer. When cleaning any part of the projector, always turn the power off and unplug the projector first. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface of it. Wipe the lens surface gently with an air spray or a soft, dry lint-free cloth. To remove dirt or stains on the lens, moisten a soft cloth with water and a neutral detergent and wipe the lens surface gently. Cleaning the Projector Case To clean the projector case, first unplug the power cable. To remove dirt or dust, wipe the casing with a soft, dry, lint-free cloth. To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent and then wipe the casing. Do not use alcohol, benzene, thinners or other chemical detergents as these can cause the casing to be warped. Cleaning the Air Filter The air filter, which is located at the bottom of the projector, should be cleaned after every 100 hours’ use. If it is not cleaned periodically, it can become clogged with dust and prevent the projector from being ventilated properly. This may cause overheating and damage of the projector. To clean the air filter : 1. Switch the projector off and unplug the power cable from the wall socket. 2. Stand the projector on it’s side so that the handle can be at the top, and you can easily access the air filter. 3. Push the opening tip of the air filter cover and remove the cover. 4. The air filter is inside the cover. To clean the filter, use a small vacuum cleaner designed for computers or other office equipment. If not, you may use a dry, lint-free cloth. If it is difficult to remove dirt or the filter is torn, contact your dealer or the service center to replace it. 5. Close the filter cover after cleaning. 6. Plug the power cable back into the wall socket. 64 Memo 65 Memo 66 Specifications MODEL RL-JA20 LCD panel size 0.87 inches resolution 1280(Horizontal) x 720(Vertical)pixel screen size 1.01~5.08m(40~200 inches) remote control distance 12m speaker system 3W horizontal / vertical ratio 16:9(horizontal:vertical) zoom ratio 1:1.3 Video compatibility NTSC/PAL/SECAM/NTSC4.43/PAL-M/PAL-N Power AC 100 - 240V~50/60Hz height 158mm(including front foot) breadth 344mm length 448.6mm(including lens) weight 4.2kg Operating Condition Projection Lamp temperature lamp model In operation : 32~95°F(0°C~35°C) In storage and transit : -4~140°F(-20°C~60°C) AJ-LA60 humidity power consumption In operation : 0~ 80% relative humidity by dry hygrometer Not in operation : 0 ~ 90% relative humidity by dry hygrometer 210W 67 Model number Serial number P/NO : 3828VA0360B a (373-026H) LG LCD PROJECTOR Please read this manual carefully before operating your set.
