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

23. Cleaning
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 TV as electric shock may occur.
Do not clean with chemicals such as alcohol, thinners or
benzene.
24. Transporting Product
Make sure the TV is turned Off and unplugged and that all
cables have been removed. It may take two or more people
to carry larger TVs. Do not press against or put stress on the
front panel of the TV during transport.
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 against the front panel of the TV with your
hand or a 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 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 are 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 contrac-
tion 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 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 “flicker”
when it is turned On. This is normal; there is nothing wrong
with the 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.
