Viewing 3D Imaging (For 3D Models) - LG 49UF690T Owner's Manual

• 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 upon the product. This generated
sound does not affect the performance and
reliability of the product.
• Take care not to touch the ventilation 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.
• Do not install this product on a wall if it could be
exposed to oil or oil mist. This may damage the
product and cause it to fall.
• If the TV feels cold to the touch, there may
be a small flicker when it is turned on. This is
normal; there is nothing wrong with TV. Some
minute dot defects may be visible on the screen,
appearing as tiny red, green, or blue spots.
However, they have no adverse effect on the TV's
performance. Avoid touching the LCD screen or
holding your 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
• 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.
• 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.
• 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.
Viewing 3D Imaging
(For 3D models)
WARNING
Viewing Environment
• Viewing Time
- When watching 3D content, take 5 to 15 minute
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
• Some users may experience a seizure or other
abnormal symptoms when they are exposed
to a flashing light or particular pattern from 3D
content.
• Do 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.
• 3D Content is not recommended for those who
suffer from stereo blindness or stereo anomaly.
Double images or discomfort in viewing may be
experienced.
• If 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 more
frequent breaks than the average adult.
• If your eyesight varies between your right and
left eye, correct your eyesight prior to watching
3D content.
Symptoms which require
discontinuation or refraining from
watching 3D content
• Do not watch 3D content when you feel fatigue
from lack of sleep, overwork, or intoxication.
• When these symptoms are experienced, stop
using/watching 3D content 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.
