SAFETY INSTRUCTIONS
CAUTION
Viewing Environment
y 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
y Infants/Children
- Usage/ Viewing 3D contents for children under the age of 6 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.
y 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 contens for a long time when
they are tired.
y Elderly
- The elderly may perceive less 3D effect compared to the young. Do not sit closer to
the TV than the recommended distance.
