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 mechanisms 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.)W05-0635-00ADJUSTMENTKDC-CMP21V8A B C D E1234567PC BOARD (COMPONENT SIDE VIEW)R135R136C106R113 R112R8W57CP3R53R35R58R78R6C9W45X1W59C24C74C75R60C68C72C70R105R114R2C4R3C5C48C61C73R106C67R104C71C69R79R80R90R101CP20C64C47R74R81R111C105R138C50C49R75 R76 R77R71R88C42R130X2R97R149CP41CP21CP40C104R82CP1R212R200C193R211 R213R30R32W26W27R37R29R31R28R215R204C194C192R202 R210C190R201 R208C80W43R40R42R25C21R23R205C1C79R108C163C191 R207 R209R203R206C139R164C167C82C77X3C78C118R139R131 R132 R133 R134X4R141R96C116CP43CP22R155C168C126C138C131C128C124C125R153C55C117L3R142R170CP45C109CP46R143R137R140 C53C134C133C127R156C135R151C145C54R91R171C142 C143C14438 1192020 123 110076755112526 50341516 117 64493233 48189163839164128103651021100255175762650IOG7675100265051 25115106VRGNDLDPDEFIOP1IOP2AGNDA+5VBU+14VR-CHL-CHAGNDGNDCH-CONCH-MUTEPARKCH-RSTREQCREQHCH-CLKSRV+8VSRVGNDELV-ELV+SYS+5VLPSDGNDD+5VSPDLO-SPLO+EJSWSCK0/MUTER/MUTELNCHOTBUDET/CHCONRESETCOMSW/MUTER/MUTELTEST2TEST1EEPWRTEST/VppBUGND BU+5VELV-ELV+SYS+5VSVDDDGNDBECBCEMVDDBU+5V BU+2.5VDGNDBUGNDSWDGND/BOOTATESTHOLDFCS-TRK+TRK-FCS-SP-SP+SL-SL+LOESWMGNDPONMCSWNTSC/PALELVADJD+2.6VVDACSWDATAHDATACLIMSWADCINFESWD+3.3VLOCKMIRRFLAGADJSELSLNSASRVSELTOFFVCCTEVOUT8V/7VARMSWSCLSDASRV+8VD+6.2VBUGNDBU+3.3V/RESETFZDTZDRXDTXDRFARFBAC+DVCGNDGNDEBEBEBEBEBEBEBD8D23D5 D4Q11Q52Q7Q8D2D3Q5CN1D60D22D61Q21Q23CN2D40Q71D71 D70IC2IC7IC17IC6IC4IC10IC11IC15IC12IC18CD PLAYER UNIT X32-5650-00 (J74-1644-11)Refer to the schematic diagram for the values of resistors and capacitors.X32-5650-00Ref.
