Viewing 3D images (continued)

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.
