	 The 3D glasses operate by receiving signals from the 3D emitter. Check that there
	is not any block in the communication area between the 3D emitter and the 3D
	glasses.
	• Is the distance between the 3D emitter and 3D glasses too far, or too close?
	 Adjust the location of the 3D emitter.
	• Are the direction of the 3D emitter and that of the infra-red reception section on the
	3D glasses misaligned?
	 Adjust the direction and location of the 3D emitter.
	• Is the 3D glasses turned off?
	 Turn on the power of the 3D glasses.
	• It may need to switch the 3D mode (such as 3D setting system) of the recorder/player
