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.
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
• 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.
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 3D-glasses do not face to the 3D synchro emitter.
• Depending on the use of 3D emitters, it may be possible that its operation might
influence the operation of other devices with infrared communication.
