SERVICE NOTES
This product is classified as a CLASS 1 LASER PRODUCT.
This label is located on the bottom of the
chassis.
This label is located on the drive unit's internal
chassis.
When replacing the chassis (T) of mechanism deck which have
the “CAUTION LABEL” attached, please be sure to put a new
CAUTION LABEL (3-223-913-11) to the chassis (T).
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 pickup block. Therefore, when checking the laser diode emission, observe 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.
