SELF-DIAGNOSIS FUNCTION
The self-diagnosis function consists of error codes for customers which are displayed automatically when errors occur, and error codes which
show the error history in the test mode during servicing. For details on how to view error codes for the customer, refer to the following box
in the instruction manual. For details on how to check error codes during servicing, refer to the following “Procedure for using the SelfDiagnosis Function (Error History Display Mode)”.
Procedure for using the Self-Diagnosis Function (Error History Display Mode).

retry err
Displays the total number of retries during recording and number of retry errors during play.
Displayed as “rππ pππ”.
“r” indicates the retries during recording while “p” indicates the retry errors during play.
The number of retries and retry errors are displayed in hexadecimal digits from 00 to FF.
total err
Displays the total number of errors.
Displayed as “total ππ”.
The number of errors is displayed in hexadecimal digits from 00 to FF.
err history
Displays the 10 latest errors.
Displayed as “0π E@@”.

value on the pick-up according to the following procedure.
Record Precedure:
1. While pressing the ENTER/YES button and π button, connect the power plug to the outlet, and release the ENTER/YES button and
π button.
2. “TEMP CHECK” will be displayed. Press the MENU/NO button to display “Check”.
3. Rotate the – ˜ + knob to display “[Service]”, and press the ENTER/YES button.
4. Rotate the – ˜ + knob to display “lop.Write”, and press the ENTER/YES button.
5. The display becomes “Ref=@@@.@” (@ is an arbitrary number) and the numbers which can be changed will blink.
6. Input the IOP value written on the optical pick-up.
To select the number : Rotate the – ˜ + knob.
To select the digit
: Press the CD SYNC/MD WM SYNC button.
7. When the ENTER/YES button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).
8. As the adjustment results are recorded for the step 6 value. Leave it as it is and press the ENTER/YES button.
9. “Complete!” will be displayed momentarily. The value will be recorded in the non-volatile memory and the display will become “Iop
Write”.
10.Press the 1/u button to complete. “Standby” will be displayed.
Display Precedure:
1. While pressing the ENTER/YES button and π button, connect the power plug to the outlet, and release the ENTER/YES button and
π button.
2. “TEMP CHECK” will be displayed. Press the MENU/NO button to display “Check”.
3. Rotate the – ˜ + knob to display “[Service]”, and press the ENTER/YES button.
4. Rotate the – ˜ + knob to display “lop.Read”.
5. “@@.@/##.#” is displayed and the recorded contents are displayed.
@@.@ : indicates the Iop value labeled on the pick-up.
##.#
: indicates the Iop value after adjustment
6. To end, press the CD SYNC/MD WM SYNC button or MENU/NO button to display “Iop Read”. Then press the 1/u button to display

TEST MODE
4-1. PRECAUTIONS FOR USE OF TEST MODE
• As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is
stopped before setting and removing it.
Even if the § button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop
rotating.

5-2. PRECAUTIONS FOR CHECKING LASER DIODE
EMISSINON
To check the emission of the laser diode during adjustments, never
view directly from the top as this may lose your eye-sight.
5-3. PRECAUTIONS FOR USE OF OPTICAL PICKUP (KMS-260A)
As the laser diode in the optical pick-up is easily damaged by static
electricity, solder the laser tap of the flexible board when using it.
Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also take
adequate measures to prevent damage by static electricity. Handle
the flexible board with care as it breaks easily.

4) Use the following tools and measuring devices.
• Check Disc (MD) TDYS-1
(Parts No. 4-963-646-01)
• Test Disk (MDW-74/AU-1) (Parts No. 8-892-341-41)
• Laser power meter LPM-8001 (Parts No. J-2501-046-A)
or
MD Laser power meter 8010S (Parts No. J-2501-145-A)
(NOTE:)
• Oscilloscope (Measure after performing CAL of prove.)
• Digital voltmeter
• Thermometer
• Jig for checking BD board waveform
(Parts No. : J-2501-149-A)
5) When observing several signals on the oscilloscope, etc.,
make sure that VC and ground do not connect inside the oscilloscope.
(VC and ground will become short-circuited.)
6) Using the above jig enables the waveform to be checked without
the need to solder.
(Refer to Servicing Note on page 6.)
7) As the disc used will affect the adjustment results, make sure
that no dusts nor fingerprints are attached to it.
Note:
When performing laser power checks and adjustment (electrical
adjustment), use of the new MD laser power meter 8010S (J-2501145-A) instead of the conventional laser power meter is convenient.
It sharply reduces the time and trouble to set the laser power meter
sensor onto the objective lens of the pick-up.

ADJUTMENT
Note:
Mode which sets the adjustment results recorded in the non-volatile
memory to the initial setting value. However the results of the
temperature compensation offset adjustment will not change to the
initial setting value.
If initial setting is performed, perform all adjustments again
excluding the temperature compensation offset adjustment.
For details of the initial setting, refer to “5-4. Precautions on
Adjustments” and execute the initial setting before the adjustment
as required.
Save the temperature data at that time in the non-volatile memory
as 25 ˚C reference data.
Note :
1. Usually, do not perform this adjustment.
2. Perform this adjustment in an ambient temperature of 22 ˚C to
28 ˚C. Perform it immediately after the power is turned on when
the internal temperature of the unit is the same as the ambient
temperature of 22 ˚C to 28 ˚C.
