MICROCOMPUTER’STERMINAL DESCRIPTION
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 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.)
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/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 re-
duce 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.
