Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.

• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be

 damaged by heat.

• Keep the temperatur e of soldering iron around 270˚C

during repairing.

• Do not touch the soldering iron on the same conductor of the

 circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

 or unsoldering.

Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.

This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER PROD-
UCT MARKING is located on
the rear exterior.

The following
caution label is
located inside of

The laser diode in the optical pick-up bloc k 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.

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,
observe from more than 30 cm away from the objective lens.

Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveform is output two times.

Insert a tapering driver into the aperture of the unit bottom, and turn
in the direction of arrow.

*

To close the disc table, turn the driver in the reverse direction.

Pull out disc table.
