• Personal computer (Refer to Servicing Notes)

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 8)

7. As the disc used will affect the adjustment results, make sure that no dusts nor fingerprints are attached to it.

8. In normal operation check after the completion of adjustment, be sure to perform the recording check (check in, check out) using the software “OpenMG Jukebox” attached.

* 1 Laser power meter

When performing laser power checks and adjustment (electrical adjustment), use of the new MD laser power meter 8010S (Part

No. : 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 optical pick-up.
