0 Material: GaAlAs

0 Wavelength: 780 nm

0 Emission Duration: continuous

0 Laser Output Power: less than 44.6 uW

* This output is the value measured at a distance of

200 mm from the objective lens surfase on the

CAUTION

Use of controls or adjustments or performance
of procedures other than those specifled herein
may result in hazardous radistion exposure.

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.
