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.

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.
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.
