While holding the magazine eject button of the changer, press the reset button of the H/U. 3. After about 3 sec

35、onds, release the magazine eject button. 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 ho

36、le on the changer mechanism. 7. Then press 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 in

37、itial position adjust- ment completes. (The data is written in the EEPROM at this time.)
