5-7. INITIAL SETTING OF ADJUSTMENT VALUE

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.

Setting Procedure :

1.Rotate the AMS knob to display “ADJ CLEAR”.

2.Press the YES button. “Complete!” will be displayed momentarily and initial setting will be executed, after which “ADJ CLEAR” will be displayed.

5-8. RECORDING AND DISPLAYING THE IOP INFORMATION

The IOP data can be recorded in the non-volatile memory. The IOP value on the label of the optical pickup and the IOP value after the adjustment will be recorded. Recording these data eliminates the need to read the label on the optical pick-up.

Recording Procedure :

1.While pressing the AMS knob and p button, connect the power plug to the outlet, and release the AMS knob and p button.

2.Rotate the AMS knob to display “[Service]”, and press the YES button.

3.Rotate the AMS knob to display “Iop.Write”, and press the YES button.

4.The display becomes Ref=@@@.@ (@ is an arbitrary number) and the numbers which can be changed will blink.

5.Input the IOP value written on the optical pick-up. To select the number : Rotate the AMS knob.

To select the digit : Press the AMS knob

6.When the YES button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).

7.As the adjustment results are recorded for the 6 value. Leave it as it is and press the YES button.

8.“Complete!” will be displayed momentarily. The value will be recorded in the non-volatile memory and the display will become “Iop Write”.

Display Procedure :

1.Rotate the AMS knob to display “Iop.Read”.

2.“@@.@/##.#” is displayed and the recorded contents are displayed.

@@.@ indicates the Iop value labeled on the pick-up. ##.# indicates the Iop value after adjustment

3.To end, press the AMS button or MENU/NO button to display “Iop Read”.

5-9. TEMPERATURE COMPENSATION OFFSET ADJUTMENT

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.

3.When D101 has been replaced, perform this adjustment after the temperature of this part has become the ambient tempera- ture.

Adjusting Procedure :

1.Rotate the AMS knob and display “TEMP ADJUST”.

2.Press the YES button and select the “TEMP ADJUST” mode.

3.“TEMP = [OK]” and the current temperature data will be displayed.

4.To save the data, press the YES button.

When not saving the data, press the MENU/NO button.

5.When the YES button is pressed, “TEMP = SAVE” will be displayed and turned back to “TEMP ADJUST” display then. When the MENU/NO button is pressed, “TEMP ADJUST” will be displayed immediatelly.

Specified Value :

The “TEMP =

” should be within “E0 - EF”, “F0 - FF”, “00 -

0F”, “10 - 1F” and “20 - 2F”.

5-10. LASER POWER ADJUSTMENT

Check the IOP value of the optical pick-up before adjustments. (Refer to 5-8. Recording and Displaying IOP Information.)

Connection :

Laser power meter

Optical pick-up objective lens

Digital volt meter

BD board

CN110 pin 5 (I+3V)

CN110 pin 4 (IOP)

Adjusting Procedure :

1.Set the laser power meter on the objective lens of the optical pick-up. (When it cannot be set properly, press the 0 button or ) button to move the optical pick-up.)

Connect the digital volt meter to CN110 pin 5 (I+3V) and CN110 pin 4 (IOP).

2.Rotate the AMS knob and display “LDPWR ADJUST”. (Laser power : For adjustment)

3.Press the YES button once and display “LD 0.9 mW $ ”.

4.Rotate the AMS knob so that the reading of the laser power meter becomes 0.85 to 0.91 mW. Press the YES button after setting the range knob of the laser power meter, and save the adjustment results. (“LD SAVE $ ” will be displayed for a moment.)

5.Then “LD 7.0 mW $ ” will be displayed.

6.Rotate the AMS knob so that the reading of the laser power meter becomes 6.9 to 7.1 mW, press the YES button and save it.

Note : Do not perform the emission with 7.0 mW more than 15 seconds continuously.
