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

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

CLASSl LASER PRODUCT
LUOKAN 1 LASERLAITE

KLASS 1 LASERAPPAHAT

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

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radia-
tion exposure

Notes on chip component replacement

0 Never reuse a disconnected chip component.

0 Notice that the minus side of a tantalum capacitor may be
damaged by heat

Flexible Circuit Board Repairing

0 Keep the temperature of soldering iron around 270°C
during repairing.

0 Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

0 Be careful not to apply force on the conductor when soldering
or unsoldering.
