finger(s) against it for long periods of time. Doing
so may produce some temporary distortion
effects on the screen.
Preventing image burn or burn-in on
your TV screen
y If a fixed image displays on the TV screen for
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.
y If the aspect ratio of the TV is set to 4:3 for a long
period of time, image burn may occur on the
letterboxed area of the screen.
y Avoid displaying a fixed image on the TV screen
for a long period of time (2 or more hours for LCD,
1 or more hours for the Plasma TV) to prevent
image burn.

(For 3D models)
WARNING
Viewing Environment
y Viewing Time
y
- When watching 3D contents, take 5 - 15 minute
breaks every hour. Viewing 3D contents for
a long period of time may cause headache,
dizziness, fatigue, or eye strain.
Those that have a photosensitive seizure or
chronic illness
y Some users may experience a seizure or other
y
abnormal symptoms when they are exposed
to a flashing light or particular pattern from 3D
contents.
y Do not watch 3D videos if you feel nausea, are
y
pregnant and/ or have a chronic illness such
as epilepsy, cardiac disorder, or blood pressure
disease, etc.
y 3D Contents are not recommended for those
y
who suffer from stereo blindness or stereo
anomaly. Double images or discomfort in
viewing may be experienced.
y If you have strabismus (cross-eyed), amblyopia
y
(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.
y If your eyesight varies between your right and
y
left eye, revise your eyesight prior to watching
3D contents.
Symptoms which require discontinuation or
refraining from watching 3D contents
y Do not watch 3D contents when you feel fatigue
y
from lack of sleep, overwork or drinking.
y When these symptoms are experienced, stop
y
using/watching 3D contents and get enough
rest until the symptom subsides.
- Consult your doctor when the symptoms
persist. Symptoms may include headache,
eyeball pain, dizziness, nausea, palpitation,
blurriness, discomfort, double image,
eyestrain, or fatigue.
CAUTION
Viewing Environment
y Viewing Distance
y
- Maintain a distance of at least twice the screen
diagonal length when watching 3D contents.
If you feel discomfort in viewing 3D contents,
move further away from the TV.
Viewing Age
y Infants / Children
y
- Usage/ Viewing 3D contents for children under
the age of 5 is not recommended.
- 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 contents.
- 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.
y Teenagers
y
- Teenagers may be stimulated to light coming
from 3D videos. Advise them not to watch 3D
videos for a long time when they are tired.
