A:Answer Thank you for your recent inquiry regarding the Sharp AQUOS LC60UQ17U. When the power button on the 3D glasses is pressed for 2 or more seconds with the power off, pairing with the TV starts. When pairing is completed successfully, the LED on the 3D glasses will blink in green for 3 seconds. To switch between 2D and 3D modes, briefly press the power button on the 3D glasses.
