OIf more installation menus appears on your TV set - select the line with B , A . - confirm with C - change the data with B , A or the number buttons 0.9 - confirm with OK . For more inform

24、ation on the various functions see Initial installation in Installing your DVD recorder. Initial installation is now complete. ENGLISH Connecting the DVD recorder 10 Preparing the remote control for operation The remote control and its batteries are packed separately in the original DVD recorder pac

25、kaging. You must install the batteries in the remote control before use - described in the following section. 1 Take the remote control and the enclosed batteries (2 batteries). 2 Open the battery compartment, insert the batteries as shown and then close the battery compartment. Match the polarities

26、 (+ and -) on the batteries with the diagram on the remote. The remote control is now ready to use. Its range is approximately 5 to 10 meters. Aim correctly Aim the remote control at the DVD recorder and not at the TV set. Connecting to the aerial To receive TV programmes you have to connect the DVD

27、-recorder to the aerial or the cable network. 1 Switch off your TV set. 2 Remove the aerial cable plug from your TV set. Insert it into the ANTENNA IN socket at the back of the DVD recorder. 3 Insert one end of the supplied aerial cable into the TV OUT socket at the back of the DVD recorder and the

28、other end into the aerial input socket at the back of the TV set. The aerial input socket of the TV set may be labeled ANT IN, RF IN, 75 ohm, etc. Check your TV instructions for details. Connecting the DVD recorder Directions For UseEN 10DVDR730/0 x3. 13 Connection with video (CVBS) cable This cable

29、, usually with yellow Cinch connectors, is used for transmitting the Composite Video signal (FBAS, CVBS). In this method of transmission the colour signal and the brightness signal are transmitted on the same cable. In certain circumstances, this can lead to slight problems with the picture, such as

30、 Moir patterns. 1 Insert one end of a video (CVBS) cable into the yellow Cinch socket VIDEO OUT (CVBS) at the back of the DVD recorder and the other end into the video input socket (usually yellow) on the TV set (usually labelled Video in or AV in. See TV operating instructions). 2 Insert one end of

31、 an audio (Cinch) cable into the red/white Cinch socket AUDIO OUT L/R at the back of the DVD recorder and the other end into the audio input socket (usually red/white) on the TV set (usually labelled Audio in or AV in. See TV operating instructions). ORead the next chapter Connecting additional devi

32、ces on how to connect additional devices (satellite receivers, videorecorders,.) to the input-/output sockets. Then, read the chapter on Connecting to the mains. Connection with the aerial cable only To connect this DVD-Recorder to a TV set without external Audio/Video input sockets, you need a modu

33、lator. With the modulator the audio/video signal is converted in an UHF-channel. This signal can be received and stored on the TV as a TV-station. Connecting to the mains Always check if the local mains voltage matches the voltage range printed on the type plate at the back or bottom of the DVD-reco

34、rder. If not consult your dealer or the customer support from your country. 1 Switch on the TV set. 2 Insert 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. PThe most important features of the DVD recorder will

35、appear in scrolling text on the display. After the first installation is completed this function will be switched off. Then, read the paragraph on Initial installation in Installing your DVD recorder. ENGLISH Connecting the DVD recorder 12 Connecting to the TV If the function Easy Link is not suppor

36、ted from your TV set, choose from the following connection methods: Connection with scart cable Connection with S?videocable Connection with Video (CVBS) cable Connection with the aerial cable only Connection with scart cable The scart or Euro AV cable serves as the universal connector for picture,

37、sound and control signals. With this type of connection, there is practically no loss of quality in picture or sound transmission. 1 Plug a scart cable into the scart socket EXT1 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

38、 operating instructions). Several scart sockets on the TV? Select the scart socket that is suitable for both video output and for video input. Selection menu for the scart socket? On some TV sets select VCR as the source for this scart socket. Read your instruction manual for your TV set for further

39、 information. ORead the next chapter Connecting additional devices on how to connect additional devices (satellite receivers, videorecorders,.) to the input-/output sockets. Then, read the chapter on Connecting to the mains. Connection with an S?Video(Y/C)cable This connecting cable, also known as t

40、he 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. 1 Insert one end of an S-Video(SVHS) cable into the S-VIDEO OUT (Y/C) socket at the back of the DVD recorder and the other end

41、into the S-Video (SVHS) input socket on the TV set (usually labelled S-Video in or SVHS in. See TV operating instructions). 2 Insert one end of an audio (Cinch) cable into the red/white Cinch socket AUDIO OUT L/R at the back of the DVD recorder and the other end into the audio input socket (usually

42、red/white) on the TV set (usually labelled Audio in or AV in. See TV operating instructions). ORead the next chapter Connecting additional devices on how to connect additional devices (satellite receivers, videorecorders,.) to the input-/output sockets. Then, read the chapter on Connecting to the ma

43、ins. Connecting the DVD recorder Directions For UseEN 11DVDR730/0 x3. 15 Connecting additional devices only via aerial cable If you want to connect additional devices (e.g. satellite receiver.) only via aerial cable, please observe the following: The DVD-Recorder must be connected directly to the TV

44、 set. If there is a video recorder or an additional device in between, the picture quality may be poor because of the copy protection system built into the DVD-Recorder. The additional device (satellite receiver) must be connected before the DVD recorder (additional device - DVD recorder - TV set).

45、Only the TV set must be connected to the TV OUT socket. If there is interference in the picture when the additional device is switched on, a TV broadcaster may be transmitting on the same channel or a channel very close to that of the additional device. (e.g.: TV broadcaster on channel 45, additiona

46、l device (satellite receiver) also on channel 45). In this case, change the channel of the additional device (satellite receiver). Consult the instruction manual of the additional device. You must also store this channel on the DVD recorder to be able to record TV programmes from the additional devi

47、ce (satellite receiver). Switch on the additional device during the installation of the DVD recorder. During the automatic channel search, the channel on which the additional device is transmitting will be stored as a TV channel. Connecting a camcorder to the front sockets To copy camcorder recordin

48、gs, you can use the front sockets. These sockets are located behind the flap on the right hand side. Digital (DV) input socket If you have a DV or Digital 8 camcorder, connect the DV IN (CAM2) input of the DVD recorder to the appropriate DV output on the camcorder. Choose ? as a programme number for

49、 this input. During recording on a DVD+RW/+R the original recording date and time are stored as DVD subtitles. On playback, this data can be displayed on the TV screen by using the E function (Subtitle). S?video input socket If you have a Hi8 or S-VHS(C) camcorder, connect the S-VIDEO (CAM1) input of the DVD recorder to the appropriate S-VHS output on the camcorder. You must also connect the audio input AUDIO L/R (CAM1) on the DVD
