Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation 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
PRODUCT MARKING is
located on the rear exterior.

This caution
label is located
inside the unit.

The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down 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.
