1. Precautions and Safety Notices 1-1. Appropriate Operation (1) Turn off the product before cleaning. (2) Use only a dry soft cloth when cleaning the LCD panel surface. (3) Use a soft cloth soaked with mild detergent to clean the display housing. (4) Disconnect the power plug from AC outlet if the product is not used for a long period of time. (5) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off. (6) Do not touch the LCD panel surface with sharp or hard objects.
human earth when handling. (7) Do not open nor modify the Module Assembly. (8) Do not press the reflector sheet at the back of the module to any directions. (9) In case if a Module has to be put back into the packing container slot after once it was taken out from the container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the CFL Reflector edge softly. Otherwise the TFT Module may be damaged.
