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 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 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.

2) Set the test mode when performing adjustments.

After completing the adjustments, exit the test mode.

Perform the adjustments and checks in “group S” of the test mode.

3) Perform the adjustments to be needed in the order shown.

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-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.
