If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block. 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.
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)
CAUTION
Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation
exposure.
This compact disc player is classified as a CLASS 1 LASER
product. The CLASS 1 LASER PRODUCT label is located on the
exterior.

z 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 (CN2)
with the extension cable (Part No. J-2502-076-1). -CD playback
You can play CD-DA (also containing CD TEXT*), CD-R/CD-
