Generated Sound
“Cracking” noise: A cracking noise that occurs when watching or turning
o 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 aect the performance and reliability
of the product.
Do not use high voltage electrical goods near the TV(e.g. electric
mosquito-swatter). This may result in product malfunction.
Viewing 3D imaging (Only 3D
models)
WARNING
Viewing environment
• Viewing Time
-- 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
• Some users may experience a seizure or other abnormal symptoms
when they are exposed to a ashing light or particular pattern
from 3D contents.
• Do not watch 3D videos if you feel nausea, are pregnant and/ or
have a chronic illness such as epilepsy, cardiac disorder, or blood
pressure disease, etc.
• 3D Contents are not recommended to those who suer 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 frequent breaks
than the average adult.
• If your eyesight varies between your right and left eye, correct your
eyesight prior to watching 3D contents.
Symptoms which require discontinuation or
refraining from watching 3D contents
• Do not watch 3D contents when you feel fatigue from lack of sleep,
overwork or drinking.
• When these symptoms are experienced, stop 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, visual
inconvenience or fatigue.
CAUTION
Viewing environment
• Viewing Distance
-- 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
• Infants/Children
-- Usage/ Viewing 3D contents for children under the age of 5
are 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 contents.
-- Children have greater binocular disparity of 3D presentations
than adults because the distance between the eyes is
shorter than that of adults. Therefore they will perceive more
stereoscopic depth compared to adults for the same 3D
image.
• Teenagers
-- Teenagers under the age of 19 may react with sensitivity
due to stimulation from light in 3D contents. Advise them
to refrain from watching 3D contents for a long time when
they are tired.
• Elderly
-- The elderly may perceive less 3D effect compared to the
young. Do not sit closer to the TV than the recommended
distance.
Cautions when using the 3D glasses
• Make sure to use LG 3D glasses. Otherwise, you may not be able to
view 3D videos properly.
• Do not use 3D glasses instead of your normal glasses, sunglasses or
protective goggles.
• Using modied 3D glasses may cause eye strain or image
distortion.
• Do not keep your 3D glasses in extremely high or low
temperatures. It will cause deformation.
• The 3D glasses are fragile and are easily scratched. Always use a
soft, clean piece of cloth when wiping the lenses. Do not scratch
the lenses of the 3D glasses with sharp objects or clean/wipe them
with chemicals.
