Ventilation
Install your 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 plugged
in. Do not install in excessively dusty
places.
Take care not to touch the ventilation
openings. When watching the TV for a
long period, the ventilation openings
may become hot.
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.
Keep the product away from direct
sunlight.
Dot Effect
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.

ANTENNAS
Outdoor antenna grounding
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 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.
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 discharge unit, connection to
grounding electrodes and requirements
for the grounding electrode.

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.
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.

Generated Sound
“Cracking” noise: A cracking noise
that occurs when watching or
turning off the TV is generated by
plastic thermal contraction 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 supplies 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.
