1 Turn on the audio/video equipment connected to the transmitter.
When the audio signal is input, the transmitter turns on automatically and the infrared emitters glow. If the transmitter is connected to the headphone jack, set the volume control of the audio source equipment as high as possible but not so high that the audio signal gets distorted. (Around level 5 or 6 on the volume control should be appropriate.)
2 Put on the headphones and the power turns on automatically.
The power indicator glows red when the power turns on.
3 Adjust the volume.
