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.
Correct methods : Incorrect Methods : Only touch the metal frame of the panel or the front cover of the monitor. Do not touch the surface of the polarizer . If the surface of the panel is pressed by fingers, this may cause "MURA." Take out the monitor by grasping the cushion. If the monitor is removed by grasping the LCD panel, that may cause "MURA.
Correct Methods : Incorrect Methods : Place the monitor on a clean & soft foam pad . ViewSonic Corporation If the monitor is placed on foreign objects, that could scratch the surface of the panel.

6. THEORY OF OPERATION This section describes the function of the LCD monitor per functional block. This monitor includes MB board, power board and button board. 6.1 MB BOARD The MB board is a two-layer, single-grounded design with ground and internal planes provided. DC power from the power board enters the board through a 6P connector. The other connector on the board is for the button board. The VGA cable is a signal cable that carries the video, sync and DDC signals from the PC VGA adapter.
d) MTV312 Micro Controller: The MTV312 micro controller (MCU) serves as the system micro controller. It programs the RTD2523 and manages other devices in the system such as the keypad, the backlight, the LED, the audio system and the non-volatile RAM using general purpose input/output (GPIO) pins.
