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.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
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:
• The recorded music is limited to private use only. Use of the music beyond this limit requires permission
of the copyright holders.
• Sony is not responsible for music files that are not saved on your computer due to unsuccessful recording
from CD or music downloading.
Other features
• Compact size, light weight.
• Skip-proof: you can enjoy uninterrupted enjoyment of music during physical activities such as
jogging or commuting.
• Approximately 10 hours of continuous playback with a rechargeable nickel hydride battery.
• Recordable time:  up to 120 min., 160 min., 240 min.**, on the supplied 128MB “MagicGate
Memory Stick.”
• Backlight LCD screen: song titles and artist names can be displayed.
• High speed data transfer using the supplied USB cable.
• OpenMG Jukebox software enables you to record compact discs using the ATRAC3 format
(high sound quality, high compression) to the hard drive.
* OpenMG and MagicGate technology conforms to the SDMI (Secure Digital Music Initiative) specifications
and allows you to enjoy digital music while maintaining the copyrights of its holders.
**Differs according to the bit rate when recording. In this case, the figures for the recordable time are when
recording on a 128MB “MagicGate Memory Stick” at 132kbps, 105kbps, and 66kbps.
