Operation to reset
The microcomputer may fall into malfunction (impossibility to
operate, erroneous display, etc.) when the power cord is un-
plugged while unit is ON or due to an external factor. In this
case, execute the following procedure to reset the micro-
computer and return it to normal condition.
Unplug the power cord from the power outlet
then, while holding the STOP 7/TUNING MODE
key depressed, plug the power cord again.
÷Please note that resetting the microcomputer clears
the contents stored in and it returns to condition
when it left the factory.

How to open the tray if it does not come out.
1. Insert a jig and turn it fully ccw in the drawing through the
hole on the loading chassis bottom.
2. Pull out the tray frontward by hand when it comes just out.
Fig .1
* How to make a jig
Insert a hex wrench to a hole of gear (W05-0881-00) in
the drawing below.
If you lost the gear use it which located on DVD mecha-
nism in the drawing (Fig .3).

Assembling and Disassembling the Opti-
cal Pickup
The optical pickup can be damaged by static electricity
from your body.
Be sure to take static electricity countermeasures when
working around the optical pickup.
Handling the Optical Pickup
1. The optical pickup is an extremely high-precision mecha-
nism. Do not subject it to strong damage.
2. Testers cannot be used to check the laser diode of the
optical pickup. The power supply in side the tester can
easily damage the laser diode.
3. Take care when handling the flexible cable because
excessive force can cause it to break.
4. To preserve the quality of the optical pickup replacement
parts during transport and installation, the terminals of the
laser diode are short-circuited. After replacing the parts,
use the proper procedure to return the laser diode to its
original condition.
Static Electricity Countermeasures
The laser diode inside the traverse unit (optical pickup )
can be damaged by static electricity from your body. Be
sure to take static electricity countermeasures when work-
ing around the optical pickup.
Static Electricity Countermeasure Methods
1. Ground yourself
Use an anti-static wrist strap to discharge static electricity
from your body.
2. Ground the workbench
Lay a conductive material (sheet) or steel sheet on the
surface where the traverse unit (optical pickup)is to be
placed, then ground the sheet.
Assembling the Optical Pickup
1. Insert a flexible cable in the arrow direction in the drawing.
2. Cut the flexible cable.

10. Repeat adjusting tilt adjustment screws 1 and 2 alter-
nately, two or three times.
*Press "SKIP UP/SKIP DOWN" keys for Tno. up or
down.
Do item 5~10 from the bottom of the main unit using a
hex wrench.
1-2 Point
1. First of all adjust tangential adjustment then adjust tilt
adjustment.
2. To get optimum point, repeat item 1 adjustment alter-
nately, two or three times.
3. Finally, adjust the tilt adjustment.
1-3 Check condition after adjustment
1. Play the disc to make sure there is no picture degrada-
tion in the inner, middle and outer peripheries, and no
audio skipping.

4-1 Setting method of the Test Mode
4-2 Cancel of the test mode
• By turning the AC off, the system is initialized and the
test mode is canceled.
• Cancel the test mode only if the power switch is turned
off.
4-3 Contents of the Test Mode
• The muting during mode selection is not controlled in
the test mode.
• During the test mode, it can be operated in a special
manner that is different from an ordinary operation by
using the keys on the main body, specifically as shown
in the following tables.
4-4 FCT(Factory) and Sub clock OSC Diagnosis
Mode
4-4-1 Sub clock OSC Diagnosis Mode
The oscillation diagnosis (existence of oscillation and
measurement of period) of a sub clock is performed
before the test mode is entered. If the diagnosis result
is OK, the system enters the test mode.
If the diagnosis result is NG, the oscillation of the sub
clock is diagnosed again. If the result is OK, the system
enters the test mode. If the diagnosis result is continu-
ously NG 5 times, the system stops with "ERR1"and
"ERR2"displayed.

Carry out AUTO pre-adjustment and write data to EEPROM.
NG_EEPROM Not write the data of setting values.
Check the connection of MD microprocessor and EEPROM.
** Carry out the TEST-PLAY , TEST-REC and C1 error in test mode after AUTO_ADJ and AUTO_AFB.
2. Test Mode
