ADJUSTMENT

● L.P.S. initial position adjustment procedure

1. 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 b y press­ing 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 dec k
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 adjust­ment completes. (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 ser vo data of the pickup
servo.
Therefore, if the EEPROM does not store servo data, ER­ROR76 (E-76) will indicate the H/U’ s display section at the
moment CD is played.

CAUTION : For continued safety, replace safety
critical components only with manufacturer’s
recommended parts (refer to parts list).

Indicates safety critical components. To re­duce the risk of electric shock, leakage-current
or resistance measurements shall be carried
out (exposed parts are acceptably insulated
from the supply circuit) before the appliance is
returned to the customer.

• DC voltages are as measured with a high

impedance voltmeter. Values may vary
slightly due to variations between individual
instruments or/and units.
