Your set consists of materials which can be recycled if disassembled by a specialized company. Please observe the local regulations regarding the disposal of packing materials, exhausted batteries and old equipment. All redundant packing material has been omitted. We have done our utmost to make the packaging easily separable into three mono materials: cardboard (box), polystyrene foam (buffer) and polyethylene (bags, protective foam sheet). Environmental information 6 For MW stations, direct the built-in antenna by turning the whole set. The telescopic antenna is not needed. Improving RADIO reception For FM stations, pull out the telescopic antenna. To improve the signal, incline and turn the antenna. Reduce its length if the signal is too strong (very close to a transmitter). For users in the U.K.: please follow the instructions on page 2. 2 Tune to the desired radio station by using the TUNING wheel. 1 Set the POWER slider to FM or MW to select the desired wave band. Radio – tuning to radio stations The bass level can also be emphasised if you place the set against wall or shelf. Do not cover any vents; leave sufficient room around the unit for ventilation. The battery supply will be switched off when the set is connected to the mains. To change over to battery supply, pull out the plug from the unit’s AC MAINS socket. 3 Connect the mains cable to the AC MAINS socket and the wall socket. This switches on the mains supply. The mains cable is inside the battery compartment. 2 If the set is equipped with a VOLTAGE selector A, set this selector to the local mains voltage. Adjust the volume using the VOLUME control. 1 Check whether the mains voltage as shown on the type plate corresponds to your local mains voltage. If it does not, consult your dealer or service organisation. The type plate is located on the bottom of the set. Increase and decrease the bass level by pressing DBB. Adjusting volume and sound Mains A Note: If you use batteries, switch the set off after use. This will avoid unnecessary power consumption. Set the POWER slider to the desired sound source: CD, TAPE, or BAND (for radio). Switching the set on and off BASIC FUNCTIONS Batteries contain chemical substances, so they should be disposed of properly. English The set is switched off when the POWER slider is set to O F F/TAPE and the keys of the tape deck are released. English Remove batteries if they are flat or if the set is not going to be used for a long time. Open the battery compartment of the set and insert 6 batteries, type R20, UM-1 or D-cells (preferably alkaline).

Protecting tapes from accidental erasure Keep the cassette side to be protected in front of you and snap off the left tab. Now, recording on this side is no longer possible. At the very beginning and end of the tape, no recording will take place in the 7 seconds during which the leader tape passes the recorder heads. The recording level is set automatically. The controls VOLUME and DBB do not affect the recording. For recording on this set you should use a cassette of the type NORMAL (IEC type I). This deck is not suitable for recording on cassettes of the type CHROME (IEC type II) or METAL (IEC type IV). Recording is permissible insofar as copyright or other rights of third parties are not infringed upon.

Solution If you are unable to solve a problem by following these hints, consult your dealer or service center. If a fault occurs, first check the points listed below before taking the set for repair. Problem Under no circumstance should you try to repair the set yourself as this will invalidate the guarantee. WARNING TROUBLESHOOTING 2-7 INSTRUCTION FOR USE English English 2-8 WARNINGS & SAFETY ESD © WARNING All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wristband with resistance. Keep components and tools at this potential. f ATTENTION Tous les IC et beaucoup d´autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévite pourrait être considérablement écourtée par le fait qu´aucune précaution nést prise à leur manipulation. Lors de réparations, s´assurer de bien être relié au même potentiel que la masse de l´appareil et enfileer le bracelet serti d´une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l´on utilise soient également à ce potentiel. ñ WAARSCHUWING Alle IC´s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal. i AVVERTIMENTO d WARNUNG Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kann die Lebensdauer drastisch reduzieren. Sorgen Sie dafür, daß sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential. Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparationi occorre quindi essere collegato allo stesso potenziale che quello della massa delápparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale. © AVAILABLE ESD PROTECTION EQUIPMENT : anti-static table mat large 1200x650x1.25mm small 600x650x1.25mm 4822 466 10953 4822 466 10958 anti-static wristband 4822 395 10223 connection box (3 press stud connections, 1MΩ) 4822 320 11307 extendible cable (2m, 2MΩ, to connect wristband to connection box) 4822 320 11305 connecting cable (3m, 2MΩ, to connect table mat to connection box) 4822 320 11306 earth cable (1MΩ, to connect any product to mat or to connection box) 4822 320 11308 KIT ESD3 (combining all 6 prior products - small table mat) 4822 310 10671 wristband tester 4822 344 13999 SAFETY © ñ Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified be used.

(accelerate ) To check Focus over the whole disc area Slide - and Discmotor can also be activated in FOCUS - test. W E2 Slide-in error Generated when the inner-switch did not close within approx. 4s when the pick up is moved inside. Inner-switch or slide motor problems. W Slide-out error Generated when the inner-switch did not open within approx. 250ms when the pick up is moved from the inner position outside. Inner-switch or slide motor problems. W Jump error. Triggered when the servo processor counts too less tracks in a defined time during JUMPS. This can be caused by a disturbed HF-signal (the tracks cannot be recognized exactly), slide motor problems, track servo problems or scratched discs. W E6 Subcode Error No valid subcode for 300ms during PLAY. W E7 PLL lock error When the PLL did not lock after 10 retries then this warning message is generated and the servo is stopped and restarted (as if the user would have pressed STOP and then PLAY immediately) to recover. W F0 Focus Search Error Triggered when the focus could not be found within 3s when starting up the CD. F F2 Fatal Subcode Error No valid subcode for more than 4s during PLAY.
