6.Press the . “R” or > “R” button so that the reading of the laser power meter becomes the specified value, press the ENTER/YES “R” button to save it.

SPECIFIED VALUE

KMS-260B

6.9 to 7.1 mW

KMS-260E

7.2 to 7.3 mW

 

 

 

 

Note: Do not perform the emission with 8.4 mW more than 15 seconds continuously.

7.Then, press the . “R” or > “R” button to display “LDPWR CHECK” (C13).

8.Press the ENTER/YES “R” button once to display “LD 0.9mW$ ”. Check that the reading of the laser power meter matches with the specified value as described in the following table.

SPECIFIED VALUE

KMS-260B

0.85 to 0.91 mW

KMS-260E

0.90 to 0.96 mW

 

 

 

 

9.Press the ENTER/YES “R” button once more to display “LD 8.4mW$ ”. Check that the reading the laser power meter and digital voltmeter satisfy the specified value.

Note down the digital voltmeter reading value.

Specified Value:

Laser power meter reading :

SPECIFIED VALUE

KMS-260B

7.0 to 0.2 mW

KMS-260E

7.25 to 0.25 mW

the Iop Information”

 

 

 

lOP = 57.6 mA in this case

lOP (mA) = Digital voltmeter reading (mV)/1 ()

10.Press the MENU/NO “R” button to display “LDPWR CHECK” (C13) and stop the laser emission.

(The MENU/NO “R” button is effective at all times to stop the laser emission)

11.Press the . “R” or >“R” button to display “Iop Write” (C05).

12.Press the ENTER/YES “R” button. When the display becomes “Ref=@@@.@” (@ is an arbitrary number), press the ENTER/YES “R” button to display “Measu=@@@.@” (@ is an arbitrary number).

13.The numbers which can be changed will blink. Input the Iop value noted down at step 9.

To select the number : Press the . “R” or >“R” button.

To select the digit :Press two buttons of VOL - and CD Z simultaneously.

14.When the ENTER/YES “R” button is pressed, “Complete!” will be displayed momentarily. The value will be recorded in the non- volatile memory and the display will become “Iop Write” (C05).

Note: After step 9, each time the ENTER/YES “R” button is pressed, the

display will be switched to “LD 0.7mW$ ”, “LD 6.2mW$

and “LD WP ” Nothing needs to be performed here.

11.Iop NV SAVE

Write the reference values in the nonvolatile memory to perform “Iop compare”. As this involves rewriting the reference values, do not perform this procedure except when adjusting the laser power during replacement of the optical pick-up and when replacing the IC102. Otherwise the optical pick-up check may deteriorate.

Note: Perform this function with the optical pick-up set at room temperature.

Procedure:

1.Press the . “R” or > “R” button to display “Iop NV Save” (C06).

2.Press the ENTER/YES “R” button and display “Iop [stop]”.

3.After the display changes to “Iop =xxsave?”, press the

ENTER/YES “R” button.

4.After “Complete!” is displayed momentarily, the display changes to “Iop 7.0 mW”.

5.After the display changes to “Iop=yysave?”, press the

ENTER/YES “R” button.

6.When “Complete!” is displayed, it means that Iop NV saving has been completed.

12. TRAVERSE ADJUSTMENT

Note 1: Data will be erased during MO reading if a recorded disc is used in this adjustment.

Note 2: If the traverse waveform is not clear, connect the oscilloscope as shown in the following figure so that it can be seen more clearly.
