Precautions for Use12 - ENGLISHImportant InformationCautions on useIn order to get the picture quality JDraw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light zfrom indoor lamps from shining onto the screen.Depending on where the projector is used, heated air from an exhaust port or warm or cold air from an air zconditioner can cause a shimmering effect on screen. Avoid use in locations where exhaust or streams of air from projector, other devices and air conditioners low between the projector and the screen.The lens of projector is affected by the heat from the luminous source. Because of this, the focusing may not zbe stable right after the power is turned on. Focusing is stabled after projecting image for 30 minutes and longer.Do not touch the surface of the projector lens with your bare hand. JIf the surface of the lens becomes dirty from ingerprints or anything else, this will be magniied and projected onto the screen.LCD Panel JThe display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-precision technology, some of the pixels on the projected image may be missing or constantly lit. Please note that this is not a malfunction. Displaying a still image for a longer time may result in an after-image on the LCD panels. If this happens, display the all white screen in the test pattern for an hour or more.Optical components JOperating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke will reduce the service life of the optical components, such as the LCD panel and polarizing plate, and may necessitate their replacement within less than one year of use. For details, consult your dealer.Lamp JThe luminous source of the projector is a mercury lamp with high internal pressure.A high pressure mercury lamp has following characteristics.The brightness of the lamp will decrease by duration of usage. zThe lamp may burst with sound or shorten life by shock or chipping. zThe life of the lamp varies greatly depending on individual speciicities and usage conditions. In particular , zcontinuous use over 12 hours and frequent on/off switching of the power greatly deteriorate the lamp and affect the lamp life.In rare cases, the lamp burst shortly after the projection. zThe risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the zlamp unit consistently. (“When to replace the lamp unit” (AE page 62))If the lamp bursts, gas contained inside of the lamp is released in a form of smoke. zIt is recommended to store replacement lamps for contingency. zIt is recommended to have authorized engineer or your dealer replace the lamp unit. zPursuant to at the directive 2004/108/EC, article 9(2)Panasonic Testing CentrePanasonic Service Europe, a division of Panasonic Marketing Europe GmbHWinsbergring 15, 22525 Hamburg, F.R.
