Precautions for Use12 - ENGLISHImportantInformationCautions on useIn order to get the picture qualityJDraw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or lightzfrom 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 airzconditioner can cause a shimmering effect on screen.Avoid use in locations where exhaust or streams of air from projector, other devices and air conditionersflow between the projector and the screen.The lens of projector is affected by the heat from the luminous source. Because of this, the focusing mayznot be stable right after the power is turned on. Focusing is stabled after projecting image for 30 minutesand longer.Do not touch the surface of the projection lens with your bare hand.JIf the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified andprojected onto the screen.DLP chipsJThe DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing orzalways lit, but this is not a malfunction.Directing a high power laser beam onto the projection window surface can damage the DLP chips.zOptical componentsJOperating the projector in an environment with high temperature or heavy exposure to dust or tobacco smokewill reduce the service life of the optical components and may necessitate their replacement within less thanone year of use. For details, consult your dealer.LampJThe 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 specificities and usage conditions. In particular,zcontinuous use over 22 hours and frequent on/off switching of the power greatly deteriorate the lamp andaffect 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 replacezthe lamp unit consistently. (Æ page 44)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.zAbout connections to computer or peripheral deviceJTo assure continued compliance, follow the attached installation instructions, which include using the providedpower cord and shielded interface cables when connecting to computer or peripheral device.Importer's name and address within the European UnionPanasonic Marketing Europe GmbHPanasonic Testing CenterWinsbergring 15, 22525 Hamburg, Germany
