SAFETY-RELATED  COMPONENT  WARNING!!
COMPONENTS  IDENTIFIED  BY  MARK  
0
  OR  DOTTED  LINE
WITH  MARK  
0
  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.
REPLACE  THESE  COMPONENTS  WITH  SONY  PARTS  WHOSE
PART  NUMBERS  APPEAR  AS  SHOWN  IN  THIS  MANUAL  OR
IN  SUPPLEMENTS  PUBLISHED  BY  SONY.
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, ob-
serve from more than 30 cm away from the objective lens.
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.
SERVICE NOTES
This label is located on the bottom of the chassis.
This label is located on the drive unit’s internal chassis.
When replacing the chassis (T.U) of mechanism deck which have
the “CAUTION LABEL” attached, please be sure to put a new
LABEL (OP CAUTION) (3-223-913-01) to the chassis (T.U).

TEST DISCS
This set can playback CD-R and CD-ROM discs. The following
test discs should be used to check the capability:
CD-R test disc TCD-R082LMT (Part No. J-2502-063-1)
CD-RW test disc TCD-W082L (Part No. J-2502-063-2)
Notes on CD-R/CD-RW discs
• You can play CD-Rs (recordable CDs)/CD-RWs (rewritable CDs)
designed for audio use on this unit.
Look for these marks to distinguish CD-Rs/CD-RWs for audio
use.
These marks denote that a disc is not for audio use.
• Some CD-Rs/CD-RWs (depending on the equipment used for
its recording or the condition of the disc) may not play on this
unit.
• You cannot play a CD-R/a CD-RW that is not finalized*.
* A  process necessary for a recorded CD-R/CD-RW disc to be
played on the audio CD player.

 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 40°C 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 350°C.
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.
EXTENSION CABLE AND SERVICE POSITION
When repairing or servicing this set, connect the jig (extension cable)
as shown below.
• Connect the MAIN board (CNP301) and the SERVO board (CN1)
with the extension cable (Part No. J-2502-011-1).
