CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the lid (CD), use
Chuck Plate Jig.
• Code number of Chuck Plate Jig: X-4918-255-1
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.
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.
This Compact Disc player is classified as a
CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT table is
location on the rear exterior.

LASER  DIODE  AND  FOCUS  SEARCH  OPERATION
CHECK
1. Open the CD lid.
2. Turn OPERATE switch on with to set the CD.
3. Turn on SW701 as following figure.
4. Press the 
^ (CD) button.
5. 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 three times for focus search.
Push on SW701 in the
arrowed direction with
a screwdriver, etc.
