4IMPORTANT SAFETY INSTRUCTIONS
yPeriodically examine the cord of your appliance, and if its
appearance indicates damage or deterioration, unplug it,
discontinue use of the appliance, and have the cord replaced
with an exact replacement part by an authorized servicer.
yPrevent dust collecting on the power
plug pins or outlet. This may cause a
fire hazard.
yProtect the power cord from physical
or mechanical abuse, such as being
twisted, kinked, pinched, closed in a
door, or walked upon. Pay particular
attention to plugs, wall outlets, and
the point where the cord exits the
appliance.
yDo not press strongly upon the panel
with a hand or sharp object such as
nail, pencil or pen, or make a scratch
on it.
yAvoid touching the screen or
holding your finger(s) against it for
long periods of time. Doing so may
produce some temporary distortion
effects on the screen.
yWhen cleaning the product and its
components, unplug the power first
and wipe it with a soft cloth. Applying
excessive force may cause scratches
or discolouration. Do not spray with
water or wipe with a wet cloth. Never
use glass cleaner, car or industrial
shiner, abrasives or wax, benzene,
alcohol etc., which can damage the
product and its panel. Otherwise,
this may result in fire, electric shock
or product damage (deformation,
corrosion or breakage).
yAs long as this unit is connected to the AC wall outlet, it is
not disconnected from the AC power source even if you turn
off this unit by SWITCH.
yWhen unplugging the cable, grab the
plug and unplug it. If the wires inside
the power cable are disconnected,
this may cause fire.
yWhen moving the product, make sure
you turn the power off first. Then,
unplug the power cables, antenna
cables and all connecting cables.
The TV set or power cord may be
damaged, which may create a fire
hazard or cause electric shock.
yWhen moving or unpacking the
product, work in pairs because the
product is heavy. Otherwise, this may
result in injury.
yContact the service center once a
year to clean the internal parts of the
product. Accumulated dust can cause
mechanical failure.
yRefer all servicing to qualified service
personnel. Servicing is required when
the apparatus has been damaged in
any way, such as power supply cord
or plug is damaged, liquid has been
spilled or objects have fallen into the
apparatus, the apparatus has been
exposed to rain or moisture, does
not operate normally, or has been
dropped.
yIf the product feels cold to the touch,
there may be a small “flicker” when
it is turned on. This is normal, there is
nothing wrong with product.
yThe panel is a high technology display
product with resolution of two million
to six million pixels. You may see tiny
black dots and/or brightly coloured
dots (red, blue or green) at a size of
1 ppm on the panel. This does not
indicate a malfunction and does not
affect the performance and reliability
of the product. This phenomenon also
occurs in third-party products and is
not subject to exchange or refund.
yYou may find different brightness and
colour of the panel depending on your
viewing position(left/right/top/down).
This phenomenon occurs due to the
characteristic of the panel. It is not
related with the product performance,
and it is not malfunction.
yDisplaying a still image (e.g., broadcasting channel logo, on-
screen menu, scene from a video game) for a prolonged
time may cause damage to the screen, resulting in retention
of the image, which is known as image sticking. The
warranty does not cover the product for image sticking.
Avoid displaying a fixed image on your television’s screen
for a prolonged period (2 or more hours for LCD, 1 or more
hours for Plasma). Also, if you watch the TV at a ratio of 4:3
for a long time, image sticking may occur on the borders
of the panel. This phenomenon also occurs in third-party
products and is not subject to exchange or refund.
yGenerated Sound
“Cracking” noise: A cracking noise that occurs when
watching or turning off the TV is generated by plastic
thermal contraction due to tempera-ture 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.

breaks every hour. Viewing 3D content for a long
period of time may cause headache, dizziness,
fatigue or eye strain.
Those that have a photosensitive seizure or
chronic illness
ySome users may experience a seizure or other
abnormal symptoms when they are exposed to a
flashing light or particular pattern from 3D content.
yDo not watch 3D videos if you feel nauseous,
are pregnant and/ or have a chronic illness such
as epilepsy, cardiac disorder, or blood pressure
disease, etc.
y3D Content are not recommended for those who
suffer from stereo blindness or stereo anomaly.
Double images or discomfort in viewing may be
experienced.
yIf you have strabismus (cross-eyed), amblyopia
(weak eyesight) or astigmatism, you may have
trouble sensing depth and easily feel fatigue due to
double images. It is advised to take frequent breaks
than the average adult.
yIf your eyesight varies between your right and left
eye, revise your eyesight prior to watching 3D
content.
Symptoms which require discontinuation or
refraining from watching 3D content

move further away from the TV.
Viewing Age
yInfants / Children
- Usage/ Viewing 3D content for children under the
age of 5 is prohibited.
- Children under the age of 10 may overreact and
become overly excited because their vision is in
development. For example: trying to touch the
screen or trying to jump into it. Special monitoring
and extra attention is required for children watching
3D content.
- Children have greater binocular disparity of 3D
presentations than adults because the distance
between the eyes is shorter than one of adults.
Therefore they will perceive more stereoscopic
depth compared to adults for the same 3D image.
yTeenagers
- Advise teenagers under the age of 19 not to watch
3D videos for a long time when they are tired.
yElderly
- The elderly may perceive less of a 3D effect than
the youth. Do not sit closer to the TV than the
recommended distance.
