DANGER
Invisible laser radiation when open and interlock failed or defeated.
Avoid direct exposure to beam.
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.
This Compact Disc player is
classified as a CLASS 1 LASER
product.
The CLASS 1 LASER
PRODUCT label is located on
the rear exterior.
Flexible Circuit Board Repairing
•Keep the temperature of the 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.
Notes on chip component replacement
•Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.

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.
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, observe from more than 30cm away
from the objective lens.
Before Replacing the Optical pick-up Block
Please be sure to check thoroughly the parameters as per the “Optical pickup Block Checking Procedure” (Part No. : 9-960-027-11) issued separately
before replacing the optical Pick-up block.
Note and specifications required to check are given below.
• FOK output : IC601 yg pin (TP610)
When checking FOK, remove the lead wire to disc motor.
• RF signal P-to-P value : 0.4 to 0.5Vp-p
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser diode is
prohibited unless the upper panel is closed while turning ON the S801 (push
switch type).
The following two checking methods for the laser diode are operable.
Method :
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. Push the S801 as shown in Fig. 1 .
3. Check the object lens for confirming normal emission of the laser diode.
If not emitting, there is a trouble in the automatic power control circuit or
the optical pick-up. During normal operation, the laser diode is turned
ON about 2.5 seconds for focus searching.
