Precautions for use16 - ENGLISHImportantInformationCautions on use■To achieve a high picture qualityz You achieve a high picture quality by drawing curtains or blinds over windows and turning off any lights near thescreen to prevent outside light or light from indoor lamps from shining onto the screen.z Depending on the conditions, the picture may wobble due to the heated air from the air exhaust port or heatedor cooled air from the air conditioner. Take care to ensure that neither the exhaust from the projector or otherequipment, nor air from any air conditioner blows on the front of the projector.z The projection lens is heated by the light from the luminous source, making the focus unstable in the period justafter switching on. The focus will stabilize after 30 minutes elapsed with the image being projected.■Do not touch the surface of the projection lens with your barehands.If the surface of the lens is contaminated by fingerprints or dirt, this will be magnified and projected onto thescreen, degrading the picture.■LCD panelThe LCD panel is precision-made. Note that in rare cases, pixels of high precision could be missing or alwayslit. This is not a malfunction.When a still image is projected for a long period, the image may burn in to the LCD panel. In this case, projectthe all white screen from the test patterns ( page 84) for at least one hour. Note, however, that it may notalways be possible to fully eradicate the burned-in image.■Optical componentsIf you are using the projecting a high-temperature environment or an environment which is dusty or full ofcigarette smoke etc., the replacement cycle for optical components such as the LCD panel and polarizer mayreduce even when duration of use is less than a year. For more information, please consult your dealer.■LampThe projector luminous source is a mercury lamp with high internal pressure.A high-pressure mercury lamp has the following characteristics.z The brightness of the lamp will decrease with usage time.z An impact, scratch, or deterioration with usage may cause the bulb burst loudly or reduce the service life.z The service life of the lamp varies greatly depending on the individual lamp and usage conditions. In particular,continuous use for periods of 24 hours or longer and frequent on/off switching of the power acceleratedeterioration in the lamp and affect the lamp life.z In rare cases, the lamp burst shortly after starting the projection.z The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace thelamp unit consistently. “When to replace the lamp unit” ( page 96)z If the lamp bursts, gas contained in the lamp is released in a form of smoke.z It is recommended that you store a replacement lamp just in case.z It is recommended that you request a qualified technician to replace the lamp unit.
