Flexible Circuit Board Repairing
-Keep the temperature of the soldering iron around 270ยฐC 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 dam-
aged by heat.This Compact Disc player is
classified as a CLASS 1 LASER
product.
The CLASS 1 LASER
PRODUCT label 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 radiation
exposure.
Laser component in this product is capable of emitting
radiation exceeding the limit for Class 1.
DANGER
Invisible laser radiation when open and interlock failed or defeated.
Avoid direct exposure to beam. Supplied accessories
For the area code of the location in which you
purchased the CD player, check the upper left side
of the bar code on the package.
AC power adaptor (1)
Headphones/earphones (1)
Hand strap (1)
For US customers
The AC power adaptor supplied is not intended to
be serviced. Should the AC power adaptor cease to
function in its intended manner, during the warranty
period, the adaptor should be returned to your
nearest Sony Service Center or Sony Authorized
Repair Center for replacement, or after warranty
period, it should be discarded.
Design and specifications are subject to change
without notice.
On AC power adaptor
-Use only the AC power adaptor supplied or
recommended in Accessories (supplied/
optional). Do not use any other AC power
adaptor. It may cause a malfunction.
Polarity of the plug
-When disconnecting the AC power adaptor
from the AC outlet, grasp the adaptor
itself. Do not pull it by the cord.
-Do not touch the AC power adaptor with
wet hands.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
-Unleaded solder melts at a temperature about 40ยฐC higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350ยฐC.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
-Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.
-Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

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 pick-
up 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

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