Viewing 3D Imaging WARNING Viewing Environment yyViewing Time - When watching 3D contents, take five- to fifteen-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 yySome users may experience a seizure or other abnormal symptoms when they are exposed to a flashing light or particular pattern from 3D contents. yyDo 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. yy3D Contents are not recommended for those who suffer from stereo blindness or stereo anomaly. Double images or discomfort in viewing may be experienced. yyIf 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. yyIf 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 yyDo not watch 3D contents when you feel fatigue from lack of sleep, overwork or drinking. yyWhen 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, eyestrain, or fatigue. IMPORTANT SAFETY INSTRUCTIONS 7 CAUTION Viewing Environment yyViewing 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 yyInfants / Children - 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. yyTeenagers - Teenagers may be stimulated by light coming from 3D videos. Advise them not to watch 3D videos for a long time when they are tired. yyElderly - The elderly may perceive less of a 3D effect than the youth. Do not sit closer to the TV than the recommended distance. Cautions when using the 3D glasses yyMake sure to use LG 3D glasses. Otherwise, you may not be able to view 3D videos properly. yyDo not use 3D glasses instead of your normal glasses, sunglasses, or protective goggles. yyUsing modified 3D glasses may cause eye strain or image distortion. yyDo not keep your 3D glasses in extremely high or low temperatures. It will cause deformation. yyThe 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. ENEGNLGISH
