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
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.

MP3 files
•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/CD-RW that is not finalized∗.
•You can play MP3 files recorded on CD-ROMs, CD-Rs, and
CD-RWs.
•A CD-R/CD-RW to which a session can be added can be played.
∗A process necessary for a recorded CD-R/CD-RW disc to be
played on the audio CD player.
EXTENSION CABLE AND SERVICE POSITION
Whenrepairingorservicing thisset,connectthe jig(extensioncable)
as shown below.
•Connect the MAIN board (CN751) and the SERVO board (CN2)
with the extension cable (Part No. J-2502-076-1).
zUNLEADED 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.

speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.
•To avoid a malfunction, do not use the built-in speaker
leads installed in your car if the unit shares a common
negative (–) lead for the right and left speakers.
•Do not connect the unit’s speaker leads to each other.
Note on connection
If speaker and amplifier are not connected correctly,
“Failure” appears in the display. In this case,make sure
the speaker and amplifier are connected correctly.
