2Photosensitive SeizuresA very small percentage of people may experience a seizure when exposed to certain visual images, including fl ashing lights or patterns that may appear in video games. Even people who have no history of seizures or epilepsy may have an undiagnosed condition that can c ause these "photosensitive epileptic seizures" while watching video games.These seizures may have a variety of symptoms, including light headedness, altered vision, eye or face twitching, jerking or sh aking of arms or legs, disorientation, confusion, or momentary loss of awareness. Seizures may also cause loss of consciousness or convulsion s that can lead to injury from falling down or striking nearby objects.Immediately stop playing and consult a doctor if you experience any of these symptoms. Parents should watch for or ask their ch ildren about the above symptoms - children and teenagers are more likely than adults to experience these seizures. The risk of photosensitive ep ileptic seizures may be reduced by taking the following precautions: ●Sit farther from the television screen. ●Use a smaller television screen. ●Play in a well-lit room. ●Do not play when you are drowsy or fatigued.If you or any of your relatives have a history of seizures or epilepsy, consult a doctor before playing.All DevicesDo Not Attempt RepairsDo not attempt to take apart, open, service, or modify the hardware device or power supply.
