extreme temperature, such as in direct sunlight, near a radiator, or heating vent. If the LCD display is exposed to extreme temperature, the LCD display may overheat and cause deformation of the enclosure or cause malfunction. • Do not install the LCD display in a place exposed to direct air conditioning. • If the LCD display is installed in such a location, moisture may condense inside and may cause a malfunction. • Do not place the LCD display in hot, oily, humid or excessively dusty places. • Do not install the LCD display where insects may enter. • Do not install the LCD display where it may be exposed to mechanical vibration. • Do not install the LCD display in a location where it may spear up, such as on or behind a pillar, or where you might bump your head on it. It may cause injury. Preventing the LCD display from toppling over To prevent the LCD display from toppling over, secure the LCD display to a wall or stand. Placement for watching We suggest you to watch the LCD display at a distance of 3-7 times that of the screen height, and not in excessive brightness. It is easy to cause eye fatigue if you watch LCD display for too long or in a dark room. To obtain clear picture, do not expose the screen to direct illumination or sunlight. Use spot lighting directed down from the ceiling if you can. LCD SCREEN • Although the LCD screen is made with high precision technology and has effective pixels of 99.99% or more, black dots or bright points or light (red, blue, or green) may appear constantly on the LCD screen. This is a structural property of the LCD panel and is not a malfunction. • The LCD screen is made with high-precision technology. To achieve a high level of performance and picture quality, this LCD display's backlight setting is set to maximize the brightness of the LCD display. However, uneven brightness may be observed when the LCD display is viewed in a dark environment without an input source or a blank screen. This is a normal condition, not a malfunction of the LCD display. To improve this condition, change the Picture mode, Backlight setting, enable the Light Sensor, or turn on the Power management. • Avoid exposing the LCD screen surface to direct sunlight. It is likely to damage the LCD panel. • Do not push or scratch the LCD screen, or place objects on top of the LCD display. The image may be uneven or the LCD panel may be damaged. • If the LCD display is used in a cold place, a smear may occur in the picture or the picture may become dark. It is not caused by a failure. This condition will improve as the temperature rises. • When still pictures are displayed continuously, ghosting may occur. It should disappear after a short period of time. • The screen and cabinet get warm when the LCD display is in use. This is a normal condition. • Spraying insect repellent with volatile material on the screen will cause damage. • Do not make prolonged contact with rubber or plastic material. Broken pieces Do not throw anything at the LCD display. Doing so may break the screen glass and cause serious injury. If the surface of the LCD display cracks, unplug the AC power cord before touching the LCD display. Otherwise electric shock may result. Handling of broken glass and liquid crystal leakage If the LCD panel gets damaged, crystalline liquid leakage may occur, or scattered broken glass may result. Do not touch broken glass or crystalline liquid which is toxic, with bare hands as cuts, poisoning or skin irritation may occur. Also do not glass fragments or leaked crystalline liquid get into your eyes or mouth. Should either contacted your eyes or mouth, rinse the contacted area thoroughly with water and consult your doctor. SERVICING Do not attempt to repair the LCD display yourself, since opening the cabinet may expose you to dangerous voltage or other hazards. Ask qualified service personnel to do the servicing for your LCD display. Replacement parts When replacement parts are required, be sure the service technician certifies in writing that he/she has used replacement parts specified by the manufacturer that have the same characteristics as the original parts. Unauthorized substitutions may cause a fire, an electric shock or other hazards. Safety check Upon completion of repairs to the LCD display, ask the service technician to perform routine safety checks (as specified by the manufacturer) to determine that the LCD display is safe for operating, and to so certify. Ask a qualified service technician to dispose of the LCD display. vii
