Solution
– This message may appear if you insert a disc that was not
finalised. DVD+R's that have not been finalised are very sensitive
to fingerprints, dust, or dirt. This may cause problems during
recording. To use the disc again, do the following :
1) Make sure that the surface of the disc is clean.
2) Press OPEN/CLOSE on the DVD recorder to open the disc
tray.
3) Insert the disc but do not close the tray.
4) Hold down button number {5} on the remote control until the
tray closes. The DVD recorder will start the repair process.
5) If the disc is recovered, the Picture Index screen will appear.
Please observe the following:
– Error during recording : The title may be missing.
– Error while changing the title/index picture : The original title/
index picture may be visible.
– Error while finalising : The disc appears not to have been
finalised.
– You can finalise the disc using the following function:
1) Press OPEN/CLOSE on the DVD recorder to open the disc
tray.
2) Insert the disc but do not close the tray.
3) Hold down button number {4} on the remote control until the
tray closes. 'FINALISING' appears on the display panel.
4) If finalising has been successful, the Picture Index screen will
appear.
– This happens if you try to copy DVDs or video cassettes that
have been copy-protected. Even though the picture on the TV is
fine, but the recording on a DVD+R(W) is faulty. This
interference is unavoidable with copy-protected DVDs or video
cassettes.
– The DVD+R(W) has recording lifetime, please change a new disc
for recording.
– Check that the cable is plugged in firmly.
– If a recording is made from a video recorder, change the tracking
on the video recorder.
– The DVD recorder may not be able to recognise the video input
signal if this signal is poor or does not comply with relevant
standards.
