The headphones battery charge level may be too low. Recharge 

the batteries or replace them with fully charged batteries. 

Ensure  that  your  TV  set,  Hi-Fi  system  or  audio  component  is 

switched on and set to a channel that broadcasts an audio signal. 

Use the headphones volume control to increase the sound level. 

The  connected  audio/video  equipment  may  not  be  in  playback 

mode. Start playback on by the equipment. 

The headphones output level is set too low. Adjust the volume to

headphones until the "Stereo" indicator comes on. 

The headphones battery charge level may be too low. Recharge 

the batteries or replace them with fully charged batteries. 

Ensure that the volume knob setting is correct. 

The headphones may be too far away from the transmitter. Move 

closer to it. 

The audio signal input level is too low. Increase the volume from 

the audio source.
