Listening to a programme

Before listening

To prevent your ears from being damaged, first lower the volume.

1 Turn on the audio/video component connected to the transmitter.

When the audio signal is input, the transmitter turns on automatically and the infrared emitters glow but they do not glow while the transmitter is charging the batteries. If the transmitter is connected to the headphone jack, set the volume control of the audio source component as high as possible but not so high that the audio signal becomes distorted.

2 Put on the headphones.

The power indicator on the upper part of the right housing glows red. Be sure to put the right housing (R) on your right ear and the left housing (L) on your left ear. Wear the headphones vertically on your head so that auto power on function is properly activated.

3 Start playback of the component connected to the transmitter.
