The digital TV receiver (DVB-T) is an extra option that can receive digital TV channels, convert them and send them on to the Rear seat entertainment module (RSE).

Two antennas are connected to the receiver so that the TV receiver is able to receive and send the channels.

DVB stands for Digital Video Broadcasting and is a series of internationally accepted open technical standards for digital television. The suffix "T" stands for Terrestrial and alludes to the subset of standards that regulate how a digital TV signal should appear when transmitted terrestrially.

The receiver in S80 (07-) is installed on the left-hand side inside the side panel, and in V70 (08-) in the storage compartment below the cargo compartment floor.

The following connections, switches and card slots can be found on the TV receiver:

Connection to the vehicle and Rear seat entertainment module (RSE) the two connectors.
Connections for two antennas.
Slot for a subscription/program card.
Serial communications port (serial port RS232).
Reset button.
Two functions switches.
Green status LED.

The TV receiver is voltage fed directly from the battery via connector #A4 for the Rear seat entertainment module (RSE) and then a fuse. The fuse holder is on the TV receiver.

To easily, see whether the receiver is voltage fed and ground switch on the ignition. The status LED should then be lit green.

Subscription/program card

Serial communications port (serial port RS232)

Used to connect a computer when updating the software.

NOTE: Special instructions are issued when this is to be performed.
