Essential information Precautions with regard to safety (continued) Cautions on use IN ORDER TO GET THE PICTURE QUALITY Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light from indoor lamps from shining onto the screen. Depending on where the projector is used, air exhaust vents or the warm air from air conditioning can cause a shimmering effect on the screen. For this reason, take care not to shield the air exhaust vents and consider the direction of the air flowing from air conditioning. DO NOT TOUCH THE SURFACE OF THE PROJECTOR LENS WITH YOUR BARE HAND. If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto the screen. Please put the standard lens cover on the projector when you do not use it. DO NOT MOVE THE PROJECTOR WHILE IT IS OPERATING OR SUBJECT IT TO VIBRATION OR IMPACT. The service life of its internal components will be shortened. THE PROJECTOR HAS A HIGH PRESSURE MERCURY LAMP THAT IS CHARACTERIZED AS FOLLOWS: • The brightness of the lamp will decrease over time. • The lamp may explode or shorten the lamp life by shocks or chipping damage. • In rare cases, it may burst shortly after the first use. • The possibility of its bursting increases when the lamp is used beyond the replacement time. • If the lamp bursts, gas inside the lamp is released in the form of smoke. • The life of a mercury lamp varies according to the individual difference or conditions of use. • In particular, turning the power on and off frequently and/or repeatedly as well as continuous use for 10 hours will greatly affect the life cycle. Provide a lamp for replacement in advance. OPTICAL COMPONENTS It may be necessary to replace the optical components such as Liquid crystal panels and Polarizing plates in less than 1 year if using the projector in a high temperature environment or in a very dusty, oily smoke or tobacco smoke environment. For more details, please contact your dealer. LIQUID CRYSTAL PANEL The Liquid crystal panels are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit, but this is not a malfunction. Do not project the same image for long periods of time, as this may remain as an afterimage on the liquid crystal panel. Display the white screen test pattern for more than an hour to remove it. See "TEST PATTERN" on page 39.
