• 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/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.

When repairing or servicing this set, connect the jig (extension cable)
as shown below.

• Connect the MAIN board (CN301) and the SERVO board (CN1)

with the extension cable (Part No. J-2502-076-1).

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.)

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.
