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

19、. 4. Press the SRC button of the H/U to enter the CD-CH mode, and the 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 hole on the changer mechanism. 7. Then pr

20、ess the DISC+ button to move the mechanism deck until the mechanisms slider hits the adjustment tool. 8. When the motor locks (stops), press the REPEAT key of the H/U. When the REPEAT key is pressed, the mechanism moves automatically to the 1st stage and the initial position adjust- ment completes.

21、(The data is written in the EEPROM at this time.) W05-0635-00 Caution : Note on IC8 (EEPROM) Be sure to use the W05-1306-00 when replacing the EEPROM. IC8 stores the digital servo data of the pickup servo. Therefore, if the EEPROM does not store servo data, ER- ROR76 (E-76) will indicate the H/Us di
