Viewing 3D images (continued)
Important:
• Iftheviewingdistanceisnearerthanthe
recommended distance, it will cause physical
discomfort and eye fatigue.
• The3Dglassesmaynotworkproperlywhenitis
used too far from the screen.
• Watchthecontentsinfrontofthescreen,notatbig
angle. If you are viewing the screen at big angle,
you may not be able to view 3D contents correctly.
• Therearepersonaldifferencesinviewingthe3D
images. For persons with myopia, hypermetropia,
astigmatism or left and right sights, please wear
glasses to correct them then wear the 3D glasses.
• Thepictureseemsmisplacedatthestartof
projecting the 3D images, however, this is not a
malfunction.
• When3DintheIMAGEmenuissettoOFF,3D
images are not displayed properly.
•
While side-by-side or top-and-bottom 3D images are
displayed, the aspect ratio setting is fixed to 16:9.
• Whenyoudisplayamenuordialogwhileviewing
side-by-side or top-and-bottom 3D images, they
are displayed in the 2D mode temporarily. When
the menu or dialog disappears, they are displayed
in the 3D mode again.
• Thekeystonesettingisinvalid(restoredtothe
default setting) while you are watching the 3D
images. The setting can not be changed.
• Whenconnectingtheprojectorandaplayersuch
as BD player through a HDMI signal distributor or
AV amplifier via HDMI cable, make sure to use the
HDMI signal distributor or AV amplifier supporting
HDMI 1.4 (3D).
• Thisprojectorcontrolstheopen/closetimingof
the 3D glasses lenses (liquid crystal shutter) by
using the infra-red signals received from the 3D
emitter. Therefore, in rare cases, a remote control of
other devices such as an air conditioner or lighting
apparatus which uses the infra-red signals may not
operate properly (while you are watching the 3D
images). However, it is not a malfunction.
Caution:
Notes on danger to public health during watching
3D image
• Stopviewingthe3Dimageimmediatelyifyoufeel
tired, discomfort, or any other abnormality. It may
cause you to feel unwell if continuing to watch the
3D image in such cases. Please take the necessary
rest, do not continue watch the 3D image for a long
time. Stop using the 3D glasses if you can clearly
see double images when viewing 3D content.
Prolonged use may cause eyesight fatigue.
• Thefollowingpeopleneedtorefrainfromuseas
with 2D image.
• aphotosensitivepatient
• apatientwithheartdisease

• averytiredperson
• adrunkperson
• children
• Whenwatching3Dmovies,takeanappropriate
break after watching a movie. When watching 3D
content on interactive devices such as 3D games
or computers, take an appropriate break every
30-60 minutes. Prolonged use may cause eyesight
fatigue.
• Whenyoufeeluncomfortable,stopviewing
3D images and playing 3D games until you are
restored. If necessary, consult a doctor. Also,
stop driving a car until you are restored (for about
2 hours). The period to restore varies with the
individual.
• Asaguide,3Dglassesshouldnotbeusedby
children younger than 5 - 6 years old. As it is
difficult to judge younger children’s reactions to
fatigue or discomfort, their physical condition may
deteriorate suddenly. When this product is being
used by a child, the parent or guardian should
check to ensure that the child’s eyes are not
becoming tired.
• Whenviewingthepicturesthatrolloverand
shake or many dynamic pictures, if you feel
uncomfortable, please look at another place.
• Whenviewingcontentswithmovementssuchas
rotation, or horizontal or vertical oscillation, you
may feel as if you are actually moving. If such a
feeling results in discomfort, look away from the
screen.
• Whenusingthe3Dglasses,becarefulnottostrike
the screen or other people by mistake. As the
images are in 3D, you may mistake the distance
from the screen, causing to strike the screen which
may result in injury. When using the 3D glasses,
do not place breakable objects near the glasses.
You may move by mistaking the 3D objects you are
viewing as the real objects, causing damages to
surrounding objects that may lead to injury.
• Whenusingthe3Dglasses,makesureyoureyes
are on an approximate horizontal level. If you
suffer from myopia (short sightedness), hyperopia
(far-sightedness), astigmatism, or have eyesight
differences between the left and right eyes, please
use corrective glasses or other such methods to
correct your eyesight before putting on the 3D
glasses.
• Whenyouviewthe3Dimages,keepadistance
from the screen of about three times the effective
height of the screen.
