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.
