3D Safety Information
Please follow all warnings and precautions as recommended before you or your child use the 3D function.
Warning
Children and teenagers may be more susceptible to health issues associated with viewing in 3D and
should be closely supervised when viewing these images.
Photosensitive Seizure Warning and Other Health Risks
Some viewers may experience an epileptic seizure or stroke when exposed to certain flashing images
or lights contained in certain Projector pictures or video games. If you suffer from, or have a family
history of epilepsy or strokes, please consult with a medical specialist before using the 3D function.
Even those without a personal or family history of epilepsy or stroke may have an undiagnosed
condition that can cause photosensitive epileptic seizures.
Pregnant women, the elderly, sufferers of serious medical conditions, those who are sleep deprived or
under the influence of alcohol should avoid utilizing the unit’s 3D functionality.
If you experience any of the following symptoms, stop viewing 3D pictures immediately and consult
a medical specialist: (1) altered vision; (2) lightheadedness; (3) dizziness; (4) involuntary movements
such as eye or muscle twitching; (5) confusion; (6) nausea; (7) loss of awareness; (8) convulsions;
(9) cramps; and/ or (10) disorientation. Children and teenagers may be more likely than adults
to experience these symptoms. Parents should monitor their children and ask whether they are
experiencing these symptoms.
Watching 3D projection may also cause motion sickness, perceptual after effects, disorientation, eye
strain and decreased postural stability. It is recommended that users take frequent breaks to lessen
the potential of these effects. If your eyes show signs of fatigue or dryness or if you have any of the
above symptoms, immediately discontinue use of this device and do not resume using it for at least
thirty minutes after the symptoms have subsided.
Watching 3D projection while sitting too close to the screen for an extended period of time may
damage your eyesight. The ideal viewing distance should be at least three times the screen height. It
is recommended that the viewer’s eyes are level with the screen.
Watching 3D projection while wearing 3D glasses for an extended period of time may cause a
headache or fatigue. If you experience a headache, fatigue or dizziness, stop viewing the 3D
projection and rest.
Do not use the 3D glasses for any other purpose than for watching 3D projection.
Wearing the 3D glasses for any other purpose (as general spectacles, sunglasses, protective goggles,
etc.) may be physically harmful to you and may weaken your eyesight.
Viewing in 3D projection may cause disorientation for some viewers. Accordingly, DO NOT place your
3D PROJECTOR near open stairwells, cables, balconies, or other objects that can be tripped over, run
into, knocked down, broken or fallen over.
