Note 2: Don’t forget to try L/R select on the Remote before proceeding.
Red Power LED should stay on solid for about 3 sec. then go off. When power
button is pressed for Power Off, the LED will blink 3 times.
A simple test is to hold the glasses about 1 ft. in front of you towards a white sheet
of paper. They should still able to see the 3D Emitter signal from the TV while
playing a 3D movie. If the glasses sync up the paper will appear as looking
through normal sun glasses, if not synced, the paper will appear amber in color.
