8Precautions on handlingPrecautions on transportMake absolutely sure that the lens cap is in place whentransporting the projector or carrying it around. Both theprojector and the projection lens are precision-madeand, as such, are susceptible to vibration and impacts.When transporting the projector and lens or carryingthem around, place them in the boxes in which theywere housed at the time of purchase, and take care tokeep them away from vibration and impacts.Precautions on installationBe sure to observe the following precautions wheninstalling the product.Avoid installing the product in a placeexposed to vibrations or impacts.If the projector is installed in a place where vibrationsare transmitted from a source of driving power andothers or mounted in a car or a vessel, vibrations orimpacts may be transmitted to the product todamage the internal parts, causing failure. Install theproduct in a place free from vibrations and impacts.Do not move the projector while it isoperating or subject it to vibration or impact.The service life of its internal motors may be shortened.Do not install the projector near high-voltage power lines or power sources.The product may be exposed to interference if itis installed in the vicinity of high-voltage electricalpower lines or power sources.Do not place the projector on a vinylsheet or carpet.If a vinyl sheet sucked up and blocks the air filterintake port, the internal temperature of theprojector may increase, which triggers theprotection circuit, turning off the power.Be sure to ask a specialized technicianwhen installing the product to a ceiling.If the product is to be installed hanging from the ceiling,purchase an optional hanging attachment (for highceiling: Model No. ET-PKD56H) (for low ceiling: ModelNo. ET-PKD55S). Please call a specialized technician orcontact an Authorized Service Centre for installation.Install the projector so that it will besupported only by its bottom panel andby none of its other parts or surfaces.Do not place the projector over 2 700 mabove sea level. When using it over 1 400m above sea level, set the “ALTITUDE”,described on page 36, to “HIGH”.Otherwise the life of the product may be shortened. Whenusing it over 2 700 m above sea level, consult your dealer.Lens FocusDo not adjust the lens focus in the initial period(within approx. 30 minutes) after switching theprojector on. The high clarity projector lens isthermally affected by the light from the light source,making the focus unstable in the period just afterswitching on. Please allow a warm-up time of atleast 30 minutes before adjusting the lens focus.Failure to do so may cause heating focus drift.DisposalTo discard the product, call the dealer or a specialized dealer.Precautions on useTo view clear images:• The audience cannot enjoy high-contrast andclear images if outside light or the illuminationinterferes the screen surface. Draw windowcurtains or blinds, turn off the lightings near thescreen or take other proper measures.• Depending on where the projector is used,there are rare occasions when hot air from theair exhaust vents or the warm air from airconditioning can cause a shimmering effect onthe screen. For this reason, take care not toshield the air exhaust vents and consider thedirection of the air flowing from air conditioning.Do not touch the surface of theprojection lens with bare hand.If fingerprints or stains are left on the projectionlens surface, they are magnified and projectedon the screen. Keep your hands away from thelens. Cover the lens with the supplied lens capwhen the projector is not used.LampA mercury lamp with high internal pressure is usedfor the light source of this product. A high-pressuremercury lamp has the following characteristics:• It may burst with a loud sound or end its life cycleby not illuminating because of given impacts,flaws, or deterioration due to used hours.• The life cycle of a mercury lamp varies accordingto the individual difference or conditions of use.In particular, turning the power on and off frequentlyand/or repeatedly will greatly affect the life cycle.• In rare cases, it may burst shortly after the first lighting.• The possibility of burst increases when thelamp is used beyond the replacement time.• If the lamp bursts, gas inside the lamp isreleased and smoke may appear.• Lamp deterioration accelerates when usedcontinuously for 24 hours or more. Lampdeterioration due to continuous use can bereduced by using the “LAMP RELAY” function.Cleaning and maintenanceBe sure to remove the power cord plug from thereceptacle before cleaning.Use soft and dry cloth to clean the cabinet.If stains are hard to remove, use a clothdampened with a kitchen detergent solution(neutral) and squeezed to wipe the cabinet andfinish with a dry cloth.
