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.
