Operation to reset

The microcomputer may fall into malfunction (impossibility to oper-

ate, erroneous display, etc.) when the power cord is unplugged

while unit is ON or due to an external factor. In this case, execute

the following procedure to reset the microcomputer and return it to

normal condition.

• Please note that resetting the microcomputer clears the contents

stored in and it returns to condition when it left the factory.

Unplug the power cord from the power outlet then, while

holding the Power key depressed, plug the power cord

again.

How to open the CD tray when it does not

come out.

1. Insert a flat driver and so on to a square hole in the

mechanism as shown in the figure.

2. Push a rack gear in the direction of arrow.

(At this time, the tray comes out slightly frontward).

3. The tray can be opened with hand.

5. Test Mode

5-1 Setting method of the Test Mode

•While pressing the "below each" key in the table, turn the power switch on.

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 continuously NG 5 times, the system stops with "ERR1" and "ERR2" displayed.

5-2 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.

5-3 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.

1. The recording start addresses of IN, MID, and OUT are

described below.

IN 30H cluster

MID 300H cluster

OUT 700H cluster

2. An erasure prevention control is not detected in the test

mode. Be careful not to enter the continuous recording

mode using a disc containing the data that should not be

erased.

3. Do not record continuously for more than five minutes.

4. Take care that no vibration is applied during continuous

recording.

8. Electrical adjustment

8-1 Precaution during confirmation of Laser Diode

emission

During adjustment, do not view the emission of a laser

diode from just above for confirmation. This may

damage your eyes.

8-2 Precaution on handling of Optical pick-up

(KMS-260B)

The laser diode in an optical pick-up is easy to be

subject to electrostatic destruction. Therefore, solder-

bridge the laser tap on the flexible board when handling

the optical pick-up.

For more information on each adjustment mode, refer to

each section of 4, "Electrical adjustment".

The number 9~13 are not used on occasion of service. If

you entered them incorrectly, press the "STOP" key

immediately to exit the mode. Specially, do not use "EEP

INITIAL".(E2PROM data has initialized if used it.)

8-7 EF Balance(Traverse Adjustment)

Connection :

TE1

Oscilloscope

X33

ADJUSTMENT +

V: 0.5V/div H: 10ms/div

INPUT: DC mode

When removing the flexible board from the connector,

make a solder bridge in advance, then remove the board.

Be careful not to remove the solder bridge before

inserting the connector. Moreover, take careful

measures against electrostatic destruction. The flexible

board is cut easily. Handle the flexible board with care.

8-3 Precaution during adjustment

1) Perform the adjustment and confirmation marked with “O”

in the order shown in the table when the parts below are

replaced.

2) In the test mode, perform the adjustment. After

adjustment is completed, cancel the test mode.

3) Perform the adjustment in the order described.

4) Use the following tools and measurement equipment.

• CD test disc TGYS-1

• Laser power meter

• Oscilloscope (with bandwidth of more than 40 MΩ)

(Calibrate the probe before measurement.)

• Digital voltmeter

• Thermometer

5) Take care that VC and GND (ground) are not connected

on the oscilloscope when two or more signals are

monitored on the oscilloscope. (VC and GND are short-

circuited in this case.)

8-4 Creating the recordable continuous recording

disc

This disc is used for focus bias adjustment and error rate

confirmation. How to create the recordable continuous

recording disc is 3-8.

CIRCUIT DESCRIPTION

1. Recordable Disc

No. Key Display/Function

1 Connect the oscilloscope to TE1 and VC in X33 pcb

Volume/

multi-control

Select [EFBAL ADJU]

3 Load the recordable disc

4 PLAY [EFBAL MO-W]

5 PLAY [EF=$✻✻MOW]

Volume/

multi-control

Write power adjustment. Adjust the waveform as follows.

7 PLAY Display shows [EF=$✻✻MOR] after [EFB=✻✻xSAVE]

to save the data in E2PROM.

Mode changes write to read

Focus and disc servo are on. Tracking servo off.

Volume/

multi-control

Read power adjustment. Adjust the waveform as follows.

9 PLAY

Save the data in E2PROM.

Display shows [EFBAL MO-P]

PLAY Display shows [EF=$✻✻MOP]

(Pickup travels to search pits and tune the servo to on.)

Volume/

multi-control

Adjust the waveform as follows.

11 PLAY Display shows[EFB=✻✻xSAVE]

to save the data in E2PROM.

Display shows [EFBAL CD] disc motor stops.

12 EJECT Unload disc.

2. Pre Master Test Disc(TGYS-1)

No. Key Display/Function

1 Load the disc(TGYS-1).

2 PLAY [EF=$✻✻CD] servo is on

Volume/

multi-control

Adjust the waveform as follows.

4 Save the data in E2PROM.

Display shows[EFB=✻✻xSAVE] in brief time.

EF PHASE

5 EJECT Unload disc.

No. Key Display/Function

1. CD Error Rate

Volume/

multi-control

[CPLAY MODE]

2 Load the test disc(TGYS-1)

3 PLAY Display shows [CPLAY MID]

Access end

[c=xxxx a=yy] xxxx=C1 error (lower 20) yy=AIDP error

4 STOP [CPLAY MODE]

5 EJECT Unload disc.

2. MO Error Rate

No. Key Display/Function

Volume/

multi-control

[CPLAY MODE]

2 Load the recordable disc

3 PLAY Display shows [CPLAY MID]

Access end

[c=xxxx a=yy] xxxx=C1 error (lower 50) yy=AIDP error(00)

4 STOP [CPLAY MODE]

5 EJECT Unload disc.

No. Key Display/Function

Volume/multi-control

Select [FBIAS ADJU]

2 Load the disc.

3 PLAY [a=xx yyyy/] point a

(xx=focus bias, yyyy=C1error)

Volume/multi-control

Adjust "yyyy" to 220

✻

5 PLAY [b=xx yyyy/] point b

Volume/multi-control

Adjust "yyyy" to 220

✻

7 PLAY [xx yyyy/] point c

Check "yyyy" within 50

8 PLAY Display shows [aa bb cc(xx)] focus bias adjust

(aa= point a,bb=b,cc=c )

During this adjustment, the oscilloscope changes in units

of about 2%. Adjust so that the waveform comes nearest

to the specified value. (MO groove read power traverse

adjustment)

(Traverse waveform)

Specification : A = B

Notes :

1. Data is erased during MO write when a recorded

disc is used for this adjustment.

2. If the traverse waveform is difficult to be monitored,

connect an oscilloscope as shown in the figure

below.

* Notes :

1. The relation between the C1 error and focus bias value

is shown in the figure below. Points “a” and “b” in the

figure are detected by the above adjustment. Focal

position “C” is automatically obtained from points “a”

and “b” by calculation.

2. The C1 error rate fluctuates. Therefore, perform the

adjustment according to the observed mean value.

8-8 Focus Bias Adjustment

Use the special disc(continuous recorded disc)

Adjust the output to maximum and

adjust the azimuth adjustment screw

for the Lissajours waveform pattern of

the oscilloscope to become close to a

CAUTION: For continued safety, replace safety

critical components only with manufacturer's rec-

ommended parts (refer to parts list). indicates

safety critical components. For continued protec-

tion against risk of fire, replace only with same

type and rating fuse(s). 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.

The DC voltage is an actual reading measured

with a high impedance type voltmeter. The mea-

surement value may vary depending on the mea-

suring instruments used or on the product. Refer

to the voltage during RECORDABLE MD PLAY

unless otherwise specified; The value shown in (
