1-6 GB NL ESD WARNING Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. 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. All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD).

9-3 9-3 Brief introduction General 1. Playback Mode 2. During High speed dubbing, a feedback signal from the uP through pin 03 of the IC7610 (HEF4094BT) will trigger the transistors 7622 (BC847B) and 7616 (BC857B) to cause a change in the voltage level between High and Low, thus changing via connector 1701. the speed of the motor. Recording Mode Recording Signal is selected and fed through by the Mode Selector IC7710 (HEF4952BT) which is then amplified by the amplifier IC7720 (AN7323S).

Service hints 10-2 CAUTION CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE CD DRIVE ELECTRONICS WHEN CONNECTING A NEW CD MECHANISM. THAT´S WHY, BESIDES THE SAFETY MEASURES LIKE • SWITCH OFF POWER SUPPLY • ESD PROTECTION ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN. The following steps have to be done when replacing the CD mechanism: 1. Disconnect flexfoil cable from the old CD drive 2. Put a paperclip on the flexfoil to short-circuit the contacts (fig.1) 3. Remove the old CD drive 4.

12-1 12-1 BRIEF INTRODUCTION OF THE AF9 BOARD The AF9 Board consists of the following features : a. TDA7468D TDA7468D (7501) provides the basic sound processing - loudness, bass, treble, volume & mute controls and source selection - TUNER, TAPE, CD & AUX including Mic mixing for the set. Sound features such as ALC, DBB, DSC and IS are controlled by the microprocessor IC on the Front Board via I2C Bus.
