CAUTION
Extra special care is required for chil-
y
dren watching a 3D video.
When Watching 3D Video
Watch 3D images within the optimum
y
viewing angle and distance.
If you are outside the viewing angle
y
or distance, you may not be able to
see 3D images. You cannot view 3D
images when you are lying down.
You may see left and right images
y
overlapped during projector
initialization after it is powered on. It
may take some time for optimization.
It may take some time for the 3D
y
image to look normal after you turn
your eyes away from the screen and
look back at the 3D image.
It may flicker slightly while watching
y
3D images under a 3 wavelength lamp
fluorescent light (50 Hz - 60 Hz) or
near windows. If so, it is recommended
to block the sun light with a curtain
and to dim the lights.
The 3D glasses must be DLP-LINK
y
(DLP Ready) type.
You may not be able to watch 3D
y
properly if there is an obstacle
between the projector and 3D
glasses.
Install the 3D projector as far as
y
possible from other devices.
If a future 3D broadcasting format
y
that is not supported by this projector
becomes the standard, an additional
device such as a set-top box may be
required.
Please check the following when
using 3D glasses.
Do not use 3D glasses as ordinary
y
glasses, sunglasses or protective
goggles.
- If you do so, this may cause injury.
Do not store 3D glasses in very hot
y
or very cold conditions. If you do, this
may cause them to become distorted.
Do not use distorted glasses.
Do not drop 3D glasses or allow
y
them to come into contact with other
objects.
- This may cause product malfunction.
The lenses of 3D glasses are easily
y
scratched. Use a soft clean cloth
when cleaning them.
Foreign particles on the cloth may
y
cause scratches.
Do not scratch the surface of the 3D
y
glasses' lenses with sharp objects
or wipe them with chemicals. If the
lenses get scratched, images may not
look normal when viewing 3D.
