yyIf water or another substance enters the product (like an AC adapter, power cord, or TV), disconnect the power cord and contact the service center immediately. Otherwise, this may result in fire or electric shock. yyUse only an authorized AC adapter and power cord approved by LG Electronics. Otherwise, this may result in fire, electric shock, malfunction, or product deformation. yyNever disassemble the AC adapter or power cord. This may result in fire or electric shock. yyKeep the product away from direct sunlight. yyNever touch this apparatus or antenna during a lightning storm. yyWhen mounting a TV on the wall, make sure not to install the TV by hanging the power and signal cables on the back of the TV. yyDo not allow an impact shock or any objects to fall into the product, and do not drop anything onto the screen. yyDISCONNECTING THE DEVICE FROM THE MAIN POWER The power plug is the disconnecting device. In case of an emergency, the power plug must remain readily accessible. yyBatteries Store the accessories (battery, etc.) in a safe location out of the reach of children. yyThis apparatus uses batteries. In your community there might be regulations that require you to dispose of these batteries properly due to environmental considerations. Please contact your local authorities for disposal or recycling information. yyDo not dispose of batteries in a fire. yyDo not short circuit, disassemble, or allow the batteries to overheat. yyDo not use high voltage electrical equipment near the TV, (e.g. a bug zapper). This may result in product malfunction. yyDot Defect The panel is a high technology product with resolution of two million to six million pixels. In a very few cases, you could see fine dots on the screen while you're viewing the TV. Those dots are deactivated pixels and do not affect the performance and reliability of the TV. yyGenerated Sound Cracking noise A cracking noise that occurs when watching or turning off the TV is generated by plastic thermal contraction due to temperature and humidity. This noise is common for products where thermal deformation is required. Electrical circuit humming/panel buzzing A low level noise is generated from a high-speed switching circuit, which supplies a large amount of current to operate a product. It varies depending upon the product. This generated sound does not affect the performance and reliability of the product. yyTake care not to touch the ventilation openings. When watching the TV for a long period, the ventilation openings may become hot. This does not affect the performance of the product or cause defects in the product. yyDo not install this product on a wall if it could be exposed to oil or oil mist. This may damage the product and cause it to fall. yyIf the TV feels cold to the touch, there may be a small flicker when it is turned on. This is normal; there is nothing wrong with TV. Some minute dot defects may be visible on the screen, appearing as tiny red, green, or blue spots. However, they have no adverse effect on the TV's performance. Avoid touching the LCD screen or holding your finger(s) against it for long periods of time. Doing so may produce some temporary distortion effects on the screen. Preventing image burn or burn-in on your TV screen yyIf a fixed image displays on the TV screen for a long period of time, it will be imprinted and become a permanent disfigurement on the screen. This is image burn or burn-in and not covered by the warranty. yyIf the aspect ratio of the TV is set to 4:3 for a long period of time, image burn may occur on the letterboxed area of the screen. yyAvoid displaying a fixed image on the TV screen for a long period of time (2 or more hours for LCD, 1 or more hours for the Plasma TV) to prevent image burn.
