1. Precautions and Safety Notices 1. Appropriate Operation (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) Turn off the product before cleaning. Use only a dry soft cloth when cleaning the LCD panel surface. Use a soft cloth soaked with mild detergent to clean the display housing. Use only a high quality, safety approved AC/DC power cord. Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.
(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist or bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module may be damaged. (12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local ordinances or regulations for disposal.
Handing and Placing methods Correct methods Only touch the metal frame of the LCD panel or the Incorrect methods Surface of the LCD panel is pressed by fingers and that front cover of the monitor, DO not touch the surfaceof may cause”mura” the POL Take out the monitor with cushions Taking out the monitor by grasping the LCD panel, that May cause”mura” ViewSonic Corporation Confidential - Do Not Copy 3 Q9b-2
