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.
