NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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

This Compact Disc player is
classified as a CLASS 1
LASER product.
The CLASS 1 LASER
PRODUCT label is located
on the bottom exterior.
CAUTION
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous radiation exposure.
Laser component in this product is capable of emitting
radiation exceeding the limit for Class 1.
Notice for customers in the United Kingdom
A moulded plug complying with BS 1363 is fitted to this
equipment for your safety and convenience.
Should the fuse in the plug supplied need to be replaced, same
rating fuse approved by ASTA or BS1 to BS 1362, (i.e. marked
with
2 or a @ mark) must be used.

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Press CD open knob.
2. Open the lid for CD.
3. Push on SWITCH (S871) as following figure.
4. Confirm the laser diode emission while observing the
objecting lens. When there is no emission, Auto Power
Control circuit or Optical Pick-up is broken.
Objective lens moves up and down once for the focus
search.
Insert a precision
screw driver and push
