SECTION 1
SERVICING NOTES
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.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat-
ic break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down 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
pickup block. Therefore, when checking the laser diode emission,

Precautions
Discs that this system CAN play
•Audio CD
•CD-R/CD-RW (audio data/MP3 files)
Discs that this system CANNOT play
•CD-ROM
•CD-R/CD-RW other than those recorded in music CD format or MP3
format conforming to ISO9660 Level 1/Level 2, Joliet
•CD-R/CD-RW recorded in multisession that have not ended by “closing
the session”
•CD-R/CD-RW of poor recording quality, CD-R/CD-RW that have
scratches or are dirty, or CD-R/CDRW recorded with an incompatible
recording device
•CD-R/CD-RW which is finalized incorrectly
•Discs containing files other than MPEG 1 Audio Layer-3 (MP3) files
•Discs of non-standard shape (for example, heart, square, star)
•Discs that have adhesive tape, paper, or sticker attached to them
•Rental or used discs with attached seals where the glue extends beyond
the seal
•Discs that have labels printed using ink that feels tacky when touched
Notes on discs
•Before playing, wipe the disc with a cleaning cloth from the centre out to
the edge.
•Do not clean discs with solvents, such as benzine thinner, or commer-
cially available cleaners or anti-static spray intended for vinyl LPs.
•Do not expose discs to direct sunlight or heat sources such as hot air
ducts, nor leave it in a car parked in direct sunlight.
•Do not use a commercial cleaning disc as it may cause the unit to mal-
function.
On safety
•Completely disconnect the power cord (mains lead) from the wall outlet
(mains) if it is not going to be used for an extended period of time. When
unplugging the unit, always grip the plug. Never pull the cord itself.
•Should any solid object or liquid get into the system, unplug the system,
and have it checked by qualified personnel before operating it again.
•AC power cord must be changed only at the qualified service shop.
On placement
•Do not place the system in an inclined position or in locations that are ex-
tremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation,
or subject to vibration, direct sunlight or a bright light.
•Be careful when placing the unit or speakers on surfaces that have been
specially treated (for example, with wax, oil, polish) as staining or discol-
oration of the surface may result.
•If the system is brought directly from a cold to a warm location or is
placed in a very damp room, moisture may condense on the lens inside
the CD player, and cause the system to malfunction. In this situation,
remove the disc, and leave the system turned on for about an hour until
the moisture evaporates.
On heat buildup
•Heat buildup on the unit during operation is normal and is not cause for
alarm.
•Do not touch the cabinet if it has been used continuously at a high volume
because the cabinet may have become hot.
•Do not obstruct the ventilation holes.
On the speaker system
This speaker system is not magnetically shielded, and the picture on nearby
TV sets may become magnetically distorted. In this situation, turn off the
TV, wait 15 to 30 minutes, and turn it back on. If there is no improvement,
move the speakers far away from the TV.
On volume adjustment
CDs reproduce sound with considerably less noise than vinyl records. For
this reason, if you raise the volume while listening to a segment containing
only noise (as you might do in the case of a vinyl record), a sudden output
of highvolume sound may cause damage to the speakers.
Make sure to lower the volume before the start of playback.
Consideration for others
Keep the volume at a moderate level out of consideration of your neigh-
bors, especially at night.
About the Hard Disk Drive
Because of its high storage density, the hard disk drive can read and write
data a very high speeds. It is, however, easily damaged by mechanical vi-
bration, shock, or dust. Although the hard disk drive is equipped with safe-
ty mechanisms to prevent the lost of data due to these factors, the following
precautions should be taken during the handling of the system.
•Do not subject the system to strong shocks or vibrations.
