IMPORTANT NOTICE: Pls note that if you switch audio source, e.g. from Netflix to Cable, TV will reset the audio settings. SO you need to RE-DO the TV audio settings again. 

Note: If you go through all the following troubleshooting but still no sound, please send the following pictures to us for double check.

1.The back of the tower so we can see how you connect the cables.

2.Your TV sound settings show external speaker / optical out / headset.

3.Your TV sound settings show PCM (only if use digital / optical cable).

 

Troubleshooting Questions Highlights:

1. Connection issue - Does LED indicator on headphones stay SOLID YELLOW-GREEN or flashes

2. Signal issue - Which audio port on TV do you plug the transmitter into? The digital optical port? the RCA port that labeled "AUDIO OUT"? the headphone jack?

3. Switch issue - Which position is the "AUDIO IN SELECT" on the transmitter switched to? OPT? COAX? RCA?

 

1. Connection Issues - Headphone and transmitter are NOT properly reconnected.

Turn off and on both headphone and transmitter, they should auto connect to each other, once connected successfully, LED indicator close to _____20180705171003.png on headphone will turn YELLOW-GREEN. (When there is no signal transmitted from the tower, the headphone light could be solid red. When ever there is audio signal transmitting from the tower, the headphone light will be turn solid green.)

Also if you want to make sure to see the solid green light on the headphone, you can turn off both the tower and headphone. Then press the headphone's power button till you see yellow-greenish light flashing, now, turn on your tower by switch the power button to on, wait for couple of second, the headphones light will turn solid yellowish green, and the light on the tower will be solid blue. Now the tower and your headphones is connected.
