● L.P.S. initial 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 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 hole

on the changer mechanism.

7. Then press the DISC+ button to move the mechanism deck

until the mechanism's 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. (The data is written in the EEPROM at

this time.)

● Caution : Note on IC8 (EEPROM)Be sure to use the W05-0869-00 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/U’s display section at the

moment CD is played.
