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

During playback

: Information such as type of disc played, part played, copyright.

These are displayed in hexadecimal.

Precedure:

1. Load a recordable disc whose contents can be erased into the unit.

2. Press the MENU/NO button. When “Edit/Menu” is displayed on the fluorescent indicator tube, rotate the – ˜ + knob to display “All

Erase?”.

3. Press the ENTER/YES button.

4. When “All Erase??” is displayed on the fluorescent indicator tube.

5. Press the ENTER/YES button to display “Complete!!”, and press the π button immediately. Wait for about 15 seconds while pressing

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.

Therefore, it will be ejected while rotating.

Be sure to press the § button after pressing the MENU/NO button and the rotation of disc is stopped.

4-1-1. Recording laser emission mode and operating buttons

• Continuous recording mode (CREC MODE)

• Laser power check mode (LDPWR CHECK)

• Laser power adjustment mode (LDPWR ADJUST)

• Traverse (MO) check (EF MO CHECK)

• Traverse (MO) adjustment (EF MO ADJUST)

• When pressing the rREC button.

4-2. SETTING THE TEST MODE

The following are two methods of entering the test mode.

Procedure 1: While pressing the ENTER/YES button and π button, connect the power plug to an outlet, and release the ENTER/YES

button and π button.

When the test mode is set “TEMP CHECK” will be displayed. Press the MENU/NO button to display “Check”.

“[Check]” will be displayed. Rotating the – ˜ + knob switches between the following four groups; ···Nn Check Nn

Adjust Nn Service Nn Develop Nn ···.

Procedure 2: While pressing the ENTER/YES button, connect the power plug to the outlet and release the ENTER/YES button.

When the test mode is set, “TEMP CHECK” will be displayed. By setting the test mode using this method, only the “Check”

group of method 1 can be executed.

4-3. EXITING THE TEST MODE

Press the 1/u button in the mode other than “TEMP CHECK”. The disc is ejected when loaded, and “Standby” display blinks, and the

STANDBY state is set.

4-4. BASIC OPERATIONS OF THE TEST MODE

All operations are performed using the – ˜ + knob, ENTER/YES button, and MENU/NO button.

The functions of these buttons are as follows.

5-3. PRECAUTIONS FOR USE OF OPTICAL PICK-

UP (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 connect-

ing 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.

• Jig for checking BD board waveform

make sure thatVC and ground do not connect inside the oscillo-

scope.

(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-2501-

145-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.

5-12. FOCUS BIAS ADJUSTMENT

Adjusting Procedure :

In this adjustment, waveform varies at intervals of approx. 2%.

Adjust the waveform so that the specified value is satisfied as

much as possible.

1. Load a test disk (MDW-74/AU-1).

2. Rotate the – ˜ + knob and display “CPLAY MODE”.

5. Rotate the – ˜ + knob and display “FBIAS ADJUST”.

6. Press the ENTER/YES button and display “ a = ”.

The first four digits indicate the C1 error rate, the two digits

after [/] indicate ADER, and the 2 digits after [a =] indicate the

focus bias value.

7. Rotate the – ˜ + knob in the clockwise direction and find the

focus bias value at which the C1 error rate becomes 220 (Refer

to Note 2).

adjustment from step 2.

In this adjustment, waveform varies at intervals of approx. 2%.

Adjust the waveform so that the specified value is satisfied as

much as possible.

13. Press the § button to remove the test disc.

Note 1 : The relation between the C1 error and focus bias is as

shown in the following figure. Find points a and b in the

following figure using the above adjustment. The focal

point position C is automatically calculated from points a

ADJUSTMENT

Checking Procedure :

1. Load a check disc (MD) TDYS-1.

2. Rotate the – ˜ + knob and display “CPLAY MODE”.

3. Press the ENTER/YES button twice and display “CPLAY MID”.

Be sure to perform this adjustment when the pickup is replaced.
