IMPORTANT SAFETY INSTRUCTIONS

This symbolindicates " dangerous voltage" inside the product that presents arisk of electric shock or personalinjury.

This symbolindicates importantinstructions accompanying the product.

Please read this manual carefully before using this product.

  • Before connecting the AC power cord ,make sure the voltage designation of the LCD TV corresponds to the local electrical supply . If you are unsure of your power supply , ask your local power company .
  • Never insert anything metallic into the cabinet openings of the liquid crystal display LCDTV/monitor; otherwise it may create the danger of electric shock.
  • To avoid electric shock, Never touch the inside of the LCD TV/monitor. Only a qualified technician should open the case of the LCD TV/monitor.
  • Never use yourLCD TV/monitor if the power cord has been damaged. Do not allow anything to reston the power cord, and keep the cord away from place where people can trip over it.
  • Be sure to hold the plug, not the cord, when disconnecting the power cord from an electric socket.
  • Openings in the LCD TV/monitor cabinet are provided for ventilation. To prevent overheating, these openings should not be blocked or covered. Also, avoid using the LCD TV/monitor on a bed, sofa, rug, or other soft surface. Doing so may block the ventilation openings in the bottom of the cabinet. If you put the LCD TV/monitor in a bookcase or some other enclosed space, be sure to provide adequate ventilation.
  • Do not expose the LCD TV/monitor to extreme temperature conditions or to extreme humidity conditions.
  • The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids.
