SERVICE NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.

The flexible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick
up block. Therefore, when checking the laser diode emission, ob-
serve from more than 30 cm away from the objective lens

Notes on Chip Component Replacement

' Never reuse a disconnected chip component.

' Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

TEST DISCS
This set can playback CD»R and CDAROM discs. The following
test dls should be used to check the capability:

CD-R test disc TCD-ROSZLMT (Part No. J-25027063e l)
CD-RW test disc TCDEWOSZL (Part No. J»2502-06372)
