Connect the changer to the HEAD UNIT (H/U).2. While holding the magazine eject button of the changer,press the reset button of the H/U.3. After about 3 seconds, release the magazine eject button.4. Press the SRC button of the H/U to enter the CD-CH mode,and the H/U's display section indicates “E-88”.5. Move the mechanism deck to around the 1st stage by press-ing the DISC- or DISC+ button.6. Insert the adjustment tool (W05-0635-00) into the tool holeon the changer mechanism.7. Then press the DISC+ button to move the mechanism deckuntil the mechanism's slider hits the adjustment tool.8. When the motor locks (stops), press the REPEAT key ofthe H/U.When the REPEAT key is pressed, the mechanism movesautomatically to the 1st stage and the initial position adjust-ment completes. (The data is written in the EEPROM atthis time.)W05-0635-00 Caution : Note on IC8 (EEPROM)Be sure to use the W05-1306-00 when replacing theEEPROM. IC8 stores the digital servo data of the pickupservo.Therefore, if the EEPROM does not store servo data, ER-ROR76 (E-76) will indicate the H/Us display section at themoment CD is played.6KDC-C719/C719YKDC-C719/G4A B C D E1234567PC BOARD (COMPONENT SIDE VIEW)CN1Q16D9D10Q8CN2D11D12Q17Q21Q22Q18D15D16D3D8Q6Q7Q11Q20Q31D7D21D22D23D24IC5IC4IC7IC9IC1C19C15C16C17C52R96C72R76R99R127R133C71C8C11C61 C63C68C69C70CP3R4R78R87R102R162R505X1X2C3C4C5 C6C7C9C10R5R7R11R12R13R14R16R53R54R59R67R68R69R70R72R73R77R79R84R97R105R106R122R123R206R502R507R506C851R851R854R855R857R85611920 38 11111162310076265025517525755176 10050 26432IGOBEBEEBEBEBEBBEEBEBEBEBVRF+T+T-F-SP-SP+SL-VC LDAD(E)(A)(D)(F)CB(C)(B)GNDCONCRSTHOTRSTX1GNDELVADJPSLSIBDETTOFFTBANKADJSELSRH(QH)8/7VSA5VSD5VPACKEFMASYTE0TE2 FE0FEIOP+PD(LD)IOP-/TSCKTDPACKTSTBTSIMGSWEJSWARMSWPONSRVSELTS2TS1/TSTBN/RWSDASCLSLNSASIM1TXHOLDEMPHFLAGDAVDDAGNDAM(DH)AVR0 LPSCOMMSWLIMSW LOESWR-CHL-CHAMUTECRSTCCONCMQHNCL B14VGNDRAGNDB14V8VBASEAVDD5VSPLO-SPLO+RF0SGNDGNDPNRFOK/RST/STB/SCKA0SSIGNDAGCDAC2C2D1LOCKRFCKPLCKC2D2C1D1DAC1DAC3C2D3C1D2ATESTMIRRSL+(ELV+)(ELV-)VDDVPPROUTLOUT(CM)EEPCCLKQC DCDH/TSCKTSOTSISDFDMDDAC0TSRMKELV-ELV+CD PLAYER UNIT X32-5810-00 (J76-0139-11)Refer to the schematic diagram for the values of resistors and capacitors.X32-5810-00Ref.
