Operating the headphones
After powering up the transmitter, the transmit light will light for approximately 
5 seconds while the transmitter initializes.
After initialization, the transmit light will go out.
Once audio is detected at any of the audio interfaces, the transmit light will 
light and the transmitter will transmit the audio signal.
By default (or if no audio is present), the transmitter will select the analog 
audio interface. As soon as a signal is detected at either one of the digital 
interfaces, the transmitter will activate the appropriate interface and light the 
corresponding interface indicator.
Set the volume control of the headphones to minimum. Then, switch on the 
headphones and slowly increase volume.
After each use, be sure to switch off the headphones to extend battery life and 
to prevent damage to the headphones from leaking batteries.
When no audio is present anymore, the transmitter will go into standby mode 
after approximately 1 minute. The transmit light will go out. During standby 
mode, no signal is transmitted. If the headphones are not used for an 
extended period of time, remove the AC adapter from the power outlet.
