ENGLISH 
The frame sequential method is a way of displaying video images left and right sequentially. The projector projects the video images used for the left- and right eyes onto the screen. The video images for the left and right side are only visible with the respective eye, as the left and right side of the 3D glasses are opened and shut by a liquid crystal shutter. As a result, the left and right images are seen by the eye and show a 3D image.

CAUTION
•As the video images for the left and right side flash alternatively when displayed, we urge you to refrain from looking at the screen with naked eyes. When viewed with several people, please prepare glasses for them.
•These 3D glasses are only for the 3D video images of this device. Please do not use it for watching other objects or 2D video images.

Operation
In order to match the timing of the display of video images and the timing of the opening/closing of the 3D glasses liquid crystal shutters and it is necessary to show to the eyes only those video images, for the left or right eye, respectively, the projector of this unit sends these timing data from the 3D synchro emitter to the 3D glasses with infrared rays.
CAUTION
•In regard to the 3D emitter, please direct the 3D glasses in such a way towards it, that the infrared rays can directly reach the 3D glasses.
•In the following cases, it may not work correctly.
•If you are near infrared communication equipment or lighting equipment.
•If the
•Depending on the use of 3D emitters, it may be possible that its operation might influence the operation of other devices with infrared communication.
