mode using a disc containing the data that should not be
erased.
4. Do not record continuously for more than five minutes.
5. Take care that no vibration is applied during continuous
recording.
2-5 Other key function
Note : An erasure prevention control is not detected in the
test mode. Notice that recording is performed irrespective
of the erasure prevention control position when the REC key
is pressed.
2-6 Precaution on use of test mode
✣An erasure prevention control is not detected in the test
mode. Therefore, when the recording laser power mode
such as continuous recording mode and traverse adjust-
ment mode is entered, the contents of the existing
recording are erased irrespective of the control position.
Be careful not to enter the continuous recording mode
and traverse adjustment mode when using a disc, con-
taining the data that should not be erased, in the test
mode.
3. Electrical adjustment
3-1 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.
3-2 Precaution on handling of Optical pick-up
(KMS-260A)
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.
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 elec-
trostatic destruction. The flexible board is cut easily. Han-
dle the flexible board with care.
3-3 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.
Function Description
3Plays back continuously when this key is pressed during
stop. Turn on and off the tracking servo when it is
pressed during continuous playback.

2) In the test mode, perform the adjustment. After adjust-
ment 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 moni-
tored on the oscilloscope. (VC and GND are short-cir-
cuited in this case.)
Note : The "#" display on the screen indicates an arbitrary
figure.
3-4 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 described below.
1. Insert a commercial recordable disc (blank disc).
2. Turn the SHUTTLE to display “CREC MODE.”
3. Press the PLAY key to display “CREC MID”.
4. After pressed the PLAY key, a display indicates
“CREC(0300)” and the recording begins.
5. Terminate the recording within five minutes.
6. Press the STOP key to stop the recording.
7. Press the EJECT key to take out the recordable disc.
As a result, a continuously recorded disc can be created for
focus bias adjustment and error rate confirmation.
Note : Take care that no vibration is applied during continu-
ous recording.
3-5 Laser power adjustment
Connection :
Adjustment :
1. Put the laser power meter on the objective lens of the
optical pick-up. Connect the digital voltmeter to TP1 and
TP2.
2. Turn the SHUTTLE to display “LDPWR ADJU”.
(Laser power : For adjustment use)
3. Press the PLAY key to display “(0.9mW)$##”.
4. Adjust to turn SHUTTLE so that the laser power meter
reads 0.86 - 0.94mW.
Set range 10mW of the laser power meter,then save to
press PLAY key.
5. “(7.0mW)$##” is displayed.
6. Adjust to turn the SHUTTLE so that laser power meter
reads 6.9-7.1mW, then save to press PLAY key.
("LDPWR<$##" is displayed momentarily.)
✣Don't output the laser power of 7.0mW more than 15sec.
7. Next turn the SHUTTLE to display "LDPWR CHEC".
8. Press PLAY key to display "(0.9mW)$##". Check the
laser power meter reads 0.85-0.95mW.
9. Next set range 10mW of the laser power meter, then
press PLAY key to display "(7.0mW)$##". Confirm that
the laser power meter and digital voltmeterat that time
read the specified value.
Specification :
Reading of laser power meter : 7.0 ±0.1 mW
Reading of digital voltmeter : Optical pick-up indication
value ±10%
(Optical pick-up label)
In this case, lop = 82.5 mA
lop(mA) = Reading of digital voltmeter (mV)/1(Ω)
10.Press the PLAY key to display “LDPWR CHEC” and
stop the laser emission. (The STOP key can be pressed
at any time to stop the laser emission.)
Note : The "#" display on the screen indicates an arbitrary
figure.
3-6 Traverse Adjustment
Connection :
Adjustment :
1. Connect the oscilloscope to (TE2) and (VC) on the X33
board.
2. Insert a commercial recordable disc.
3. Turn the SHUTTLE to display “EFBAL ADJU”.

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.
C1 error
Focus bias value
3-8 Error rate confirmation
3-8-1 CD error rate confirmation
Confirmation :
1. Insert test disc TGYS-1.
2. Turn the SHUTTLE to display “CPLAY MODE”.
3. Press the PLAY key to display “CPLAY MID”.
4. “C=#### a=##” is displayed.
5. Confirm that the C1 error rate is less than 20.
6. Press the STOP key to stop the playback, than press the
EJECT key to take out a test disc.
3-8-2 MO error rate confirmation
1. Insert a continuously recorded disc ( refer to 3-4,
"Creating the recordable continuous recording disc")
2. Turn the SHUTTLE to display “CPLAY MODE”.
3. Press the PLAY key to display “CPLAY MID”.
4. “C=#### a=##” is displayed.
5. Confirm that the C1 error rate is less than 50 and that
ADIP error rate is 00.
6. Press the STOP key to stop the playback, then press the
EJECT key to take out a test disc.
Note : The "#" display on the screen indicates an arbitrary
figure.

The DC voltage is an actual reading measured with a
high impedance type voltmeter. The measurement value
may vary depending on the measuring instruments used
or on the product. Refer to the voltage during
RECORDABLE MD PLAY unless otherwise specified;
The value shown in ( ) is the voltage measured at the
moment of STOP. The voltage followed by (REC) refers
to the value during MD RECORDING.
CAUTION: For continued safety, replace safety critical
components only with manufacturer's recommended
parts (refer to parts list). indicates safety critical
components. For continued protection 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 measurement value may
vary depending on the measuring
instruments used or on the product.
Refer to the voltage during
RECORDABLE MD PLAY unless
otherwise specified; The value shown in
( ) is the voltage measured at the
moment of STOP. The voltage followed
by (REC) refers to the value during MD
RECORDING.
CAUTION: For continued safety, replace
safety critical components only with
manufacturer's recommended parts
(refer to parts list). indicates safety
critical components. For continued
protection 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.

CAUTION: For continued safety, replace safety critical components only with
manufacturer's recommended parts (refer to parts list). indicates safety critical
components. For continued protection 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 insu-
lated 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 measurement value may vary depending on the
measuring instruments used or on the product. Refer to the voltage dur-
ing RECORDABLE MD PLAY unless otherwise specified; The value
shown in ( ) is the voltage measured at the moment of STOP. The volt-
age followed by (REC) refers to the value during MD RECORDING.
