ANTENNAS
Outdoor 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 cir-
cuits 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.
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 dis-
charge unit, connection to grounding elec-
trodes and requirements for the grounding
electrode.

Cleaning
When cleaning, unplug the power cord and
scrub 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.
Moving
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 against or put stress on the front
panel of the TV.
Ventilation
Install your TV where there is proper ventila-
tion. 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
plugged in. Do not install in excessively dusty
places.
Take care not to touch the ventilation open-
ings. 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 proudct.
If you smell smoke or other odors coming from
the TV or hear strange sounds, unplug the power
cord contact an authorized service center.
Do not press strongly upon the panel with
hand or sharp object such as nail, pencil or
pen, or make a scratch on it. Do not allow a
impact shock onto the panel.
Keep the product away from direct sunlight.
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'reviewing the
TV. Those dots are deactivated pixels and do
not affect the performance and reliability of the
TV.
Generated Sound
"Cracking" noise: A cracking noise that occurs
when watching or turning off the TV is gener-
ated by plastic thermal contraction 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 supplies a large
amount of current to operate a product. It
varies depending on the product.This generat-
ed sound does not affect the performance and
reliability of the product.
