18、itial position adjustment procedure1. 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

19、H/Us 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

20、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

21、 (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 BOA
