Rear seat entertainment module (RSE)





Note! There may be a slight delay between selecting a DVD function with the remote control and activation of the DVD player function. A message will appear on the screen to confirm that the DVD function was selected. Display of 'Not permitted' indicates that the DVD player is still processing a previously selected function.

The rear seat entertainment system is supplied with electric power and is controlled by the rear seat entertainment module (RSE) (16/109).
The control module also includes the DVD player for the system.
The system is powered via X-feed and directly from the battery. If the system is operating when the ignition is switched of, a question will appear on the screens as to whether continued play is permitted.
If the user answers YES, the system will continuing playing another 10 minutes. The system will then shut down. If there is no response to the question, the system will shut down after 1 minute. As a means of safeguarding the battery, play time cannot be extended unless the ignition is switched on again.
All buttons will light for approximately 5-10 seconds when attempting to start the system using the POWER button on the DVD player in this mode, they will then go out. Accordingly, the system is not permitted to start before the ignition has been switched on again.
If the system is to be switched on using the remote control, the ignition must be switched on and the remote control must be pointed at one of the screens before any buttons are depressed, the receiver for the signals from the remote control is located on the lower edge of the screens.
When the remote control is aimed at a screen (16/81A, B) and a function key is pressed in, the Rear seat entertainment module (RSE) identifies the selected screen and executes the command that the remote control sent out.
If, for example, you press a menu selection button, a menu opens on the screen at which the remote control was aimed. The possible selections are described below:
- Independent shifting of three audio/video inputs (DVD and AUX).
- Image adjustment (image color, brightness, contrast and aspect ratio).
- Audio settings (bass, treble and volume).
- Language selection for on-screen instructions.
- Switch individual screens ON/OFF.
Rear seat entertainment module (RSE) also decides which media source that has been linked to the selected screen and transmits command in a suitable protocol.
If, for example, the left screen is set for DVD-playback and an infrared play command is detected at the left screen, the message is received, saved and forwarded to the DVD-player (16/109) in the DVD-player's infrared protocol.
A fixed memory saves the displayed instruction language used and the current audio and video settings for the respective output channel. These settings are loaded upon start-up with the exception of volume level, which is set to low as standard.
When a DVD disc is inserted in the opening DVD playback starts automatically if the DVD disc does not have a disc menu.
DVD playback can resume from a paused position, for example, if the ignition was switched off when watching a movie. In this case playback continues from the last position when the ignition is switched on again. The audio and video signals are fed out from the DVD player from the connection block (ISO connection) at the rear of the device.

System start-up procedure
When the ignition is switched on the Rear seat entertainment module (RSE) performs a basic internal system check and starts the start-up procedure with the screens.
Depending on software, the start-up times are different and handling of the POWER-button's lighting. Version of software can be identified using the SERVICE MENU, see: Design Design
The following takes place:

Playback of audio in the vehicle's fixed audio system




In order to playback audio from the DVD player using the vehicle's ordinary audio system the Rear seat entertainment module (RSE)/DVD player is connected to the AUX input on the Integrated Audio Module (IAM).
Audio from the DVD-player or AUX-input can be selected as audio source on Integrated Audio Module (IAM) by selecting input signal "AUX" in the audio system's menu system.
When Rear seat entertainment module (RSE)/DVD-player plays a disc, the audio is automatically sent out on the outputs to the Integrated Audio Module (IAM). But no sound will be heard in the speakers until "AUX" has been selected as the audio source.

Note! If an audio source is connected to the AUX input's 3.5 mm stereo connection, the audio signals from the Rear seat entertainment module (RSE)/DVD player to the Integrated Audio Module (IAM) are disconnected.

Infrared (IR) control




Each screen houses an IR-receiver. The IR-receivers are connected to the rear seat entertainment module (RSE) (16/109) and are activated when the rear seat entertainment module (RSE) is supplied power. When a button is pressed on the remote control, it emits a signal with infrared light. The coding of this signal varies depending on which button was pressed. The IR-signal is received by the IR-receiver below the respective head restraint screen (16/81A, B) and is forwarded to the rear seat entertainment module (RSE) for processing.
The remote control can be used to switch between different audio and/or video inputs in the system:
- DVD player, audio/video
- AV-panel, audio or audio/video
- Audio/video from a TV receiver (if installed) to one or both screens.
Selection is performed by aiming the remote control at the screen where the command is to be executed.
Depending on which of the two screens that received the command, the Rear seat entertainment module (RSE) will select AV- or audio source for that screen. Then the remote control can be aimed at the other screen to select source for that screen.

Headphones




The system includes two pairs of IR headphones as standard. Any number of headphones can be used as long as they are within range of the IR transmitter.
Sound is transferred from the screen to the wireless headphones via an infrared signal. There must be free travel between the transmitter in the bottom edge of the screen and the receivers on the side of the headphones. If the way is blocked, the signal may be interfered with and sound quality will thus deteriorate.
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.

Note! Lowering the volume of the screen will increase the signal/noise ratio of the headphones. Optimal headphone output is obtained by setting screen volume to 75%. Headphone volume can then be regulated using the wheel on the headphones themselves.
