IMPORTANT SAFETY INSTRUCTIONS

(Continued from previous page)

22.Outdoor Antenna Grounding

If an outside antenna or cable system is connected to the product, 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 into contact with such power lines or circuits as death or serious injury can occur.

Be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges.

Article 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 con- ductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

Antenna Grounding According to NEC, ANSI/NFPA 70

27.	If you smell smoke or other odors coming from the TV or
	hear strange sounds, unplug the power cord, and contact
	an authorized service center.
28.	Do not press strongly on the panel with a hand or sharp
	object (e.g., a nail, pencil, or pen) or make a scratch on it.
29.	Keep the product away from direct sunlight.
30.	Dot Defect
	The Plasma or LCD 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.
31.	Generated Sound
	“Cracking”: A cracking noise that occurs while the TV is On
	or when it is turned Off is generated by plastic thermal con-
	traction due to temperature and humidity. This noise is com-
	mon 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 sup-
	plies a large amount of current to operate a product. It varies
	depending on the product. This generated sound does not
	affect the performance and reliability of the product.

32. For LCD TV

If the TV feels cold to the touch, there may be a small “flick-

er” 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 monitor’s per-

formance. 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.

23.Cleaning

When cleaning, unplug the power cord and rub gently with a soft cloth to prevent scratching. Do not spray water or other liquids directly on the TV as electric shock may occur. Do not clean with chemicals such as alcohol, thinners or benzene.

24.Transporting Product

Make sure the product is turned Off and unplugged and that all cables have been removed. It may take two or more peo- ple to carry larger TVs. Do not press against or put stress on the front panel of the TV.

25.Ventilation

Install the 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 (e.g., plastic) while it is plugged in. Do not install in excessively dusty places.

26.Do not touch the ventilation openings, as they may become hot while the TV is operating.
