ENGLISH Connecting the DVD recorder 12 When you install your DVD recorder for the first time, select one of the following options: Connecting with a scart cable and Easy Link If your TV set is equipped with Easy Link, Cinema Link, NexTView Link, Q-Link, Smart Link, Megalogic, Datalogic, . and you wish to use a scart cable. Connecting with a scart cable without Easy Link If your TV set is not equipped with Easy Link, Cinema Link, NexTView Link, Q-Link, Smart Link, Megalogic, Datalogic, . and you wish to use a scart cable. Connecting with an S?Video(Y/C)cable If your TV set is equipped with an S-Video(SVHS) socket. Connecting with video(CVBS) cable If your TV set is equipped only with an video(CVBS) socket. Connecting with a scart cable and Easy Link Your DVD recorder can exchange information with your TV set using Easy Link. Your TV channels can also be transferred in the same order from your TV set to your DVD recorder using Easy Link. Please see your TVs operating instructions. Have the following cables ready: an aerial cable (1, supplied), a mains cable (2, supplied), a special scart cable (3, suitable for Easylink). 1Switch off your TV set. 2Remove the aerial cable plug from your TV set. Insert it into the ANTENNA IN socket at the back of the DVD recorder. 3Insert one end of the supplied aerial cable into the TV OUT socket at the back of the DVD recorder and the other end into the aerial input socket at the back of the TV set. 4Plug in a full-pin scart cable (all 21 contacts wired) into the scart socket EXT 1 TO TV-I/O at the back of the DVD recorder and the corresponding scart socket - suitable for Easylink - at the back of the TV set (see TV set operating instructions). Connectingthe DVD recorder Directions For UseEN 12DVDR77/0 x3. 15 8If the connection was properly made and your TV was automatically switched to the programme number for the scart socket, e.g. EXT, 0, AV, you will see the following picture: Virginmode Menu Language English Espaol Franais Italiano Deutsch PressOKto continue aMy screen is empty. b Depending on the initializing period it can take some time before you see the picture on the TV. b Many TV sets are switched by the DVD recorder to the programme number for the scart socket by way of a control signal sent through the scart cable. b If the TV set does not automatically switch to the scart socket programme number, manually change to the corresponding programme number on your TV set (see your TVs operating instructions). b Check that the scart cable is connected from the TV set to the EXT 1 TO TV-I/O socket on the DVD recorder. The EXT 2 AUX-I/O socket is intended only for additional devices.Problem Then, read the paragraph on Initial installation in Installing your DVD recorder. Connecting with an S?Video(Y/C)cable This connecting cable, also known as the SVHS cable, is used to transmit the brightness signal (Y signal) and colour signal (C signal) separately. This mini DIN socket/plug is also called a Hosiden socket/plug. Have the following cables ready: an aerial cable (1, supplied), a mains cable (2, supplied), an S-Video(SVHS) cable (3), an audio cable (4, supplied, red/white plug). 1Remove the aerial cable plug from your TV set. Insert it into the ANTENNA IN socket at the back of the DVD recorder. 2Insert one end of the supplied aerial cable into the TV OUT socket at the back of the DVD recorder and the other end into the aerial input socket at the back of the TV set. ENGLISH Connecting the DVD recorder 14 Connecting with a scart cable without Easy Link Have the following cables ready: an aerial cable (1, supplied), a mains cable (2, supplied), a scart cable (3). 1Remove the aerial cable plug from your TV set. Insert it into the ANTENNA IN socket at the back of the DVD recorder. 2Insert one end of the supplied aerial cable into the TV OUT socket at the back of the DVD recorder and the other end into the aerial input socket at the back of the TV set. 3Plug a scart cable into the scart socket EXT 1 TO TV-I/O at the back of the DVD recorder and the scart socket for the DVD recorder at the back of the TV set (see TV set operating instructions). My TV set has several scart sockets. Which one should I use? Select the scart socket that is suitable for both video output and for video input. My TV set shows me a selection menu for the scart socket Select VCR as the source for this scart socket. ? 4Read the next chapter Connecting additional devices on how to connect additional devices (satellite receivers, videorecorders,.) to the input-/output sockets. 5Switch on the TV set. 6Insert one end of the supplied mains cable into the mains socket 4MAINS at the back of the DVD recorder and the other end into the wall socket.
