Please refer to the user manualsfor your other audio equipment first.Digital recordings (optical or coaxial) give the bestperformance in audio and usability (e.g. auto-track). (The digital optical connection is less sensitive to externaldisturbances). If your equipment does not offer digital connections, the highquality Analog-Digital-Convertor of your CD recorder willensure very good audio performance when recordings aremade from the analog input. Playback via the digital coaxial output of the CD recordergives the best audio performance.If your equipment does not offer digital connections, the highquality Digital-Analog-Convertor of the CD recorder ensures avery good sound quality via the analog output.Weadvise you to always establish both digital and analogconnections. In this way you can always make analogrecordings when digital recording is not possible.Wehave described the most common ways of connecting theCD recorder. If you still have difficulties with the connectionsyou can always contact the Philips Consumer Service desk inyour country.Connections generalEASYJOGSTORE/MENUCANCEL/DELETEAUDIO CD PLAYBACKENTERREMTRACKRECTIMEDIGITAL OPTICAL ANALOGPROG SHUFFLE REPEAT SCANI ICDRWCHANGERSYNCMANUALRECORDREMTOTALALLTRACKTIMESTEPTRACKCDRWMENU messages - See Menu modeDISPLAYINSTALLATIONEnglish10Messages, as listed and explained here, may appear on thedisplay for your guidance.General READING.reading disc informationOPEN.during tray openingCLOSE.during tray closingNO DISC.no disc inserted, disc unreadableor disc inserted upside downPROG FULL.program fullINSERT DISC.insert disc or insert disc in correctwayWRONG DISC/.inserted disc is not an audio CDUSEAUDIOCDUNFINALIZED.unfinalized CDR(W) disc MEMORY XXù.indicates the amount of textmemory used for unfinalized discsRecording WAIT.- when STOP 9is pressed during recording- when STOP 9is pressed duringrecording the first 4 seconds of atrackUPDATE.updating disc contentsDISC FULL.no more recording possibleDIGITAL 1.digital coaxial input 1 selectedOPTICAL.digital optical input selectedANALOG.analog input selected COPY PROTECT.no digital recording can be madeof the external sourceNOTFINALIZED.when opening the tray with anunfinalized disc inserted (CD recorder)RECORD FAST.high speed recording selectedREC LISTEN.listen speed recording selectedMAKE CD.high speed recording of acomplete disc and Auto Finalizefunction selectedREC EXT DISC.synchronised start of recordingfrom external source selectedREC EXT MAN.manual start of recording fromexternal source selected_XX DB.level is being adjustedDOESNOTFIT.time left on CDR(W) disc is notenough for proposed recordingANALOG REC.copy prohibited track found duringrecording.
