yyDo not attempt to modify this product in any way without written authorization from LG Electronics. Unauthorized modification could void the user’s authority to operate this product.
yyOutdoor Antenna Grounding
(Can differ by country):
If an outdoor antenna is installed, follow the precautions below. An outdoor antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can come in contact with such power lines or circuits as death or serious injury can occur. Be sure the antenna system is grounded to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code (NEC) in the U.S.A. provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements for the grounding electrode.

yyCleaning
When cleaning, unplug the power cord and wipe gently with a soft cloth to prevent scratching. Do not spray water or other liquids directly on the
4
TV as electric shock may occur. Do not clean with chemicals such as alcohol, thinners, or benzine.
yyMoving
Make sure the product is turned off, unplugged, and all cables have been removed. It may take 2 or more people to carry larger TVs. Do not press or put stress on the front panel of the TV.
yyVentilation
Install your TV where there is proper ventilation. Do not install in a confined space such as a bookcase. Do not cover the product with cloth or other materials while plugged in. Do not install in excessively dusty places.
yyIf you smell smoke or other odors coming from the TV, unplug the power cord and contact an authorized service center.
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.
