Solution
– Check the recorder audio connection. Read chapter "Basic
Recorder Connections - Connecting the audio cables" for
details.
– Set the Analogue output or Digital output correctly, based on
the device you have connected to this recorder. Read chapter
"System Menu Options - Audio Output settings" for details.
– Have your aerial or cable TV signal checked.
– Install the TV channel. Read chapter "System Menu Options -
Analogue Channel settings - Auto Search" for details.
– This message may appear if you insert a disc that was not
fi nalised or contains junk data. DVD±Rs that have not been
fi nalised are very sensitive to fi ngerprints, 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 this 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. This 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 fi nalising : The disc appears not to have been
fi nalised.
– Check that the cable is plugged in fi rmly.
– If a recording is made from a video recorder, change the
tracking on the video recorder.
– This recorder may not be able to recognise the video input
signal if this signal is poor or does not comply with relevant
standards.
– No aerial signal received for the current channel or no video
signal received from the external input channel (EXT1, EXT2,
CAM1 or CAM2).
– Check the antenna connection.
– Check the connection and turn on the connected device.
– To use the EPG, the analogue tuner has to be installed. Installing
only the digital tuner will result in no EPG service information.
– Turn off the recorder to standby mode for at least 24 hours. It
will enable downloading of TV listings data.
– Make sure that no timer recording is programmed during this
timing, as it will interrupt the EPG downloading.
