IMPORTANT SAFETY INSTRUCTIONS
Ventilation
y y
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 while
plugged. Do not install in excessively dusty
places.
If you smell smoke or other odors coming
y y
from the TV, unplug the power cord and
contact an authorized service center.
Do not press strongly upon the panel with
y y
your hand or a sharp object such as a nail,
pencil or pen, or make a scratch on it.
Keep the product away from direct sunlight.

Dot Defect
y y
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.
Generated Sound
y y
"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.
Take care not to touch the ventilation
y y
openings. 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 product.
Preventing "Image burn" or "Burn-in" on your TV screen
If a fixed image displays on the TV screen for
y y
a long period of time, it will be imprinted and
become a permanent disfigurement on the
screen. This is "image burn" or "burn-in" and
not covered by the warranty.
If the aspect ratio of the TV is set to 4:3 for a
y y
long period of time, image burn may occur on
the letterboxed area of the screen.
Avoid displaying a fixed image on the TV screen
y y
for a long period of time (2 or more hours for
LCD, 1 or more hours for the Plasma TV) to
prevent image burn.
