64 Projector Cleaning, Lens Replacement, Air Inlet Cleaning Clean your projector when it is dirty or image projection is poor. Clean the air inlets every 100 hours in practice. Warning: The projector cabinet should only be opened by trained service personnel. The projector contains several high voltage components which can cause electric shock. For internal checks, repairs and cleaning, contact your dealer or the nearest address provided at “International Warranty Conditions” in “Safety Instructions/World-Wide Warranty Terms” included in the package. Use care when handling the power plug and connector. Improper handling may cause fire or electric shock. When handling the plug, observe the following. · Do not insert a plug or connector into an outlet or port if it is dirty or holds foreign matter. · Insert the plug and connector firmly and completely. · Do not pull out the plug or connector with wet hands. Caution: Never attempt to remove the lamp immediately after use. · Heat may cause burns or other injury. · Wait approximately 60 minutes after switching off power and remove the lamp after the projector has cooled completely. When performing operations, pull the power plug and connector out of the outlet and port respectively. Switch off power to the projector and disconnect the power cord before cleaning. Cleaning the Projector Unit Wipe dirt from the projector lightly with a soft cloth. For heavier dirt, wipe the projector lightly with a cloth soaked in a weak solution of mild detergent and wrung out thoroughly, then dry with a separate cloth. Do not use waxes, benzene, thinners, or other volatile substances. These may degrade the cabinet or strip the finish. Cleaning the Lens Clean the lens with a commercial blower or lens cleaning paper. The surface of the lens is easily scratched and should not be rubbed or struck with hard objects.
65 Cleaning the Air Inlets Accumulated dust in the air inlets degrades ventilation, increases the interior temperature, and can cause malfunction. To prevent debris from entering the air inlets, always stand the projector upright with the lens upward. Then use a vacuum cleaner or other equipment to suck dust from the inlets. Tip: If it is no longer possible to remove the dirt from the air inlets, it is time to replace them. Consult your vendor.
66 Lamp Replacement Replace the lamp with a new lamp in the following instances. A replacement lamp is an optional part (sold separately). (Model No: ELPLP16) [When the following message is displayed for 30 seconds after projection begins: Lamp Replace. After the replacement of the lamp, reset the lamp timer under the direction in the user’s manual.] [When the problem/alarm display indicator flashes red at 1-second intervals.] [When brightness or picture quality is inferior to its original state.] Tip: If the lamp does not light, replace it even if the lamp life has not expired. To maintain the original brightness and picture quality, replacement messages are set for approximately 1,400 hours. If you continue to use the lamp after this period, the possibility of the lamp breaking becomes greater. When the lamp replacement message appears, replace the lamp with a new one as soon as possible, even if it is still working. Though a replacement message appears at approximately 1,400 hours, individual lamp characteristics or usage conditions may cause failure before 1,400 hours, and we recommend that a replacement lamp be kept on hand. Contact your dealer for a spare lamp. Replacement Tip: Install the lamp securely. For safety, when the lamp cover is opened, the abnormal warning display indicator flashes red, and the projector lamp goes out. If the lamp or lamp cover is installed improperly, the lamp will not light. A message will be displayed. Problem/alarm display indicator flashes red at 1-second intervals
