Mitsubishi Electric DLP HC7800D User Manual page 27

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 person in poor physical condition
• a sleepy person
• 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.
