Careless handling duringrepair can reduce life drastically.When repairing, make sure that you are connected with thesame potential as the mass of the set via a wristband withresistance. Keep components and tools at this potential.fATTENTIONTous les IC et beaucoup dautres semi-conducteurs sontsensibles aux dcharges statiques (ESD).

If it does not, consultyour dealer or service organisation. The type plate is locatedon the bottom of the set.2 If the set is equipped with a VOLTAGE selector A, set thisselector to the local mains voltage.3 Connect the mains cable to the AC MAINS socket and the wall socket. This switches on the mains supply. The mains cable isinside the battery compartment.The battery supply will be switched off when the set is connectedto the mains. To change over to battery supply, pull out the plugfrom the units AC MAINS socket.To disconnect the set from the mains completely, remove the mainsplug from the wall socket.AMainsBatteries5 6 SEARCH.searches backward/forwardin a CD trackFUNCTIONSBASIC14POWER:CD, TAPE, BAND.selects the sound source2DBB.enhances the bass3VOLUME.adjusts the volume level(back of the set)p.3.5mm headphone socketAUSENote: Connecting the headphones will switchoff the speakers.5CASSETTE RECORDERPogram;.interrupts recording orplaybackOPENSTOP / 9.stops the tape and opensthe cassette compartmentSEARCH 6 .rewinds the tapeSEARCH 5 .fast forwards the tapePLAY 1.starts playbackRECORD 0 .starts recording6 .Sensor for the infraredremote controlRADIO7TUNING.tunes to radio stations1BAND: FM, MW.selects the wave band8CD PLAYEROPENCLOSE .opens the CDcompartment9.stops CD play and erasesthe program2;.starts and interrupts CDplay .skips and searchesforward.skips and searchesbackwardCD MODE.selects the different CDplaying modes andprograms tracks9 .DisplayREMOTE CONTROLSHUFFLE.plays CD tracks in randomorderREPEAT .repeats a track, the entireCD or the pr2;.starts and interrupts CDplay .selects the beginning ofthe current, a previous or asubsequent track of a CD9.stops CD play and erasesthe programREMOTESENSORPLAYRECORDSEARCHOPENST OPPAUSESTOPPLAYPAUSESEARCHSEARCHBA S S R E F L E XCD MODEVOLUMEVOLUMEA Z 1 0 5 5PROGRAMBASSREFLEXBASSREFLEXCD RADI O CASSETTERECORDEDDIG ITAL AU DIOCO MP AC T8973SEARCHSEARCHREPEATSHUFFLE54612INSTRUCTIONS FOR USE3-2PCS 104 276Set the POWER slider to the desired sound source:CD, TAPE, or BAND (for radio).The set is switched off when the POWER slider is set to OFFOFF/TAPEand the keys of the tape deck are released.Note: If you use batteries, switch the set off after use. This willavoid unnecessary power consumption.Adjust the volume using the VOLUME control.Increase and decrease the bass level by pressing DBB.The bass level can also be emphasised if you place the set againstwall or shelf. Do not cover any vents; leave sufficient room aroundthe unit for ventilation.1 Set the POWER slider to FM or MW to select the desired wave band.2 Tune to the desired radio station by using the TUNING wheel.Improving RADIO receptionFor FM stations, pull out the telescopic antenna. To improve thesignal, incline and turn the antenna. Reduce its length if the signal is too strong (very close to a transmitter).For MW stations, direct the built-in antenna by turning the wholeset. The telescopic antenna is not needed.AM/FM5363FM103105107BASSREFLEXBASSREFLEXBASS REFLEXSPEAKERSYSTEM-VOLUME+REMOTECONTROLPLAYRECORDSEARCHPAUSESTOPOPENCLOSECD RADIO CLASSETTE RECORDINGAZ1035SHUFFLEPROGRAMAM/FM5363FM103105107BASSREFLEXBASSREFLEXBASSREFLEXSPEAKERSYSTEM-VOLUME+REMOTECONTROLPLAYRECORDSEARCHPAUSESTOPOPENCLOSECD RADIO CLASSETTE RECORDINGAZ1035SHUFFLEPROGRAMAZ1035CD RADIO CASSETTE RECORDERFM AM170130100806353kHzx 10MHz100969288104108OPENCLOSECDSYNCHROSTARTRECORDINGRadio tuning to radio stationsVOLUMECD RADIO CASSETTE AZ1035DYNAMIC BASS BOOSTAdjusting volume and soundTAPECDFMAMCD RADIO CASSETTE RAZ1035DYNAMIC BASS BOOSTPOWEROFFSwitching the set on and off1 Set the POWER slider to CD.2 Press / OPEN to open the CD compartment.3 Insert an audio CD (printed side up) and close the CDcompartment.
