Instructions for 3D cinema glasses
The active glasses X101 work in automatic mode – there is no power switch to turn the glasses "ON"
or "OFF". Upon receiving the glasses, they are in the off‐mode, meaning that the glasses periodically
check for the valid IR signal. In the off‐mode the lenses appear green. Upon receiving the IR signal,
the glasses start a warm‐up sequence.
Warm‐up sequence ‐ During the warm‐up period the lenses remain opaque for the entire warm‐up
period which lasts for two seconds. At the end of a warm‐up period the glasses go into normal run‐
mode. In this mode, the lenses open and close in sync with the projector to deliver the 3D experience
to the viewer.
Clear mode ‐ When in run‐mode, after the glasses loose a valid synchronization signal, they go to a
clear mode (both lenses clear). In the clear mode, both lenses remain open, so that the viewer can
see normally through the glasses. The lenses remain open until the glasses are able to receive a sync
signal. If they don't receive the signal in five minutes they go to an off‐mode.
Battery life ‐ The glasses check for a low battery condition just before going to the "off‐mode". If the
battery life is insufficient the lenses will begin blinking slowly (the lenses are closed and briefly flash
open simultaneously once every two seconds) to indicate a low battery condition and prevent the
glasses from going to run‐mode. The control circuit is designed so that a low battery condition does
not appear during the run‐mode when watching a movie.
Replacing the battery ‐ Access to the battery is provided through an opening on the interior side of
the frame that is sealed off by a cover. In the case of dead battery, the seal is opened using a key,
