Rear seat entertainment module (RSE)
Hint: AUX-input (16/123.2) in XC90 has number 17/40.1.
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 power fed and controlled by the Rear seat entertainment module (RSE) (16/109). The control module also includes the system's DVD player.
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 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.
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.
For further information, see: System start-up procedure System Start-Up Procedure
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, TV (if installed) 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.
- Service menu to reach settings such as selection of region code, TV receiver, etc.
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
See: System start-up procedure System Start-Up Procedure
Playback of audio in the vehicle's fixed audio system
Hint: AUX-input (16/123.2) in XC90 has number 17/40.1.
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
There is an infrared receiver (IR receiver) in each screen. The IR receivers are directly connected to the Rear seat entertainment module (RSE) (16/109) and are activated when the Rear seat entertainment module (RSE) is voltage fed. When a button is pressed on the remote control a signal is sent out with infrared light (IR). This signal has a different coding depending on the button pressed. The IR signal is received by the IR receiver under the screen (16/81A, B) on each head restraint 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
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.
Note! The audio signal from the screens to the headphones has a fixed sound level. This means the headphone volume can only be adjusted using the knob on the headphones.
Showing TV programs
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. At the same time a wake-up signal is sent to the TV receiver and the TV receiver's green status LED comes on.
When the start-up procedure for the screens has finished and the illuminated buttons on the DVD player, except the POWER button, have gone out the TV receiver's status LED also goes out.
When the system is switched on using e.g. the POWER button on the DVD player the status LED comes on.
When the remote control is directed towards a screen (16/81A, B) and the function button to select the signal source (DVD/AUX/TV) is pressed a menu is displayed. The TV receiver can be selected as the "source" from the menu. When the TV receiver is selected, the last tuned channel is shown. If no channel has been stored a channel menu is shown.
Note! The direction of the antenna and the current reception conditions determine the picture quality. If the picture breaks up or freezes, if the audio stutters or if some channels disappear this is probably due to a weak antenna signal. The signal was affected among others by the lay of the land, weather conditions and the position of the vehicle in relation to the TV transmitter, consequently the problem can appear in connection with movements, time of the year, weather conditions.
