Rear Seat Entertainment System (RSE), Generation 4.3 (2009-10): Function: Headphones
Two pairs of headphones are supplied with the system as standard. The transfer of sound between the screen and the wireless headphones takes place using an infrared signal (IR). Any number of headphones can be connected provided that they are within the working range of the IR transmitters.
There must be a clear path between the transmitter on the lower edge of the screen and the receiver on the side of the headphones. If the path is blocked the signals may be disrupted and the audio quality impaired.
The headphones are switched on with the switch located on the side. The headphones switch off automatically if no IR signal is received for 3-4 minutes.
The headphones also have a button to set which audio channel to listen to. Channel A or B can be selected. Channel A is always transmitted from the left screen and channel B is always transmitted from the right screen.
