Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C during
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.
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.
TABLE OF CONTENTS
• Replacement of TMS320DA150GGU120 (IC601) used in the set requires
a special tool.
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.
zUSABLE FORMAT
Use ISO9660 Level 1 format.

Basic Operations
Transferring songs from the computer to
Network Walkman (Check-out)
1 Install the supplied OpenMG Jukebox software and import digital audio files to
OpenMG Jukebox.
For details, refer to the OpenMG Jukebox operating instructions.
Note
Before connecting the pla er to our computer for the first time, be sure to install "OpenMG Jukebox"
software and NW-E7/E10 driver from the supplied CD-ROM to our computer.
If ou have alread installed "OpenMG Jukebox" software, ou also need to install NW-E7/E10 driver before
connecting the pla er to our computer.
2 Connect Network Walkman to our computer.
3 Connect Network Walkman to our
computer.
Connect the small connector of the supplied
USB cable into the USB jack on the USB
cradle, then the large connector to the USB
jack of our computer.
“PC” appears in the displa , and the access
lamp flashes to confirm access to the
computer.
1Attach our Network Walkman to the USB cradle.
2 Connect the AC power adaptor*.
Connect the supplied AC power adaptor to
an AC wall outlet first, then to the DC IN
jack on the USB cradle.
* You can use the pla er b onl connecting the
dedicated USB cable, but the batter is not be
charged.
Note
Be sure to attach the pla er to the
arrow direction as illustrated below.

Basic Operations
Notes
• Do not disconnect the USB cable or remove the pla er from the USB cradle during the access lamp is flashing.
This ma cause the data being transferred to be broken.
• Do not connect more than two USB devices to our computer. Normal operation will not be guaranteed.
• Use of this pla er with a USB hub or a USB extension cable is not guaranteed.
• A malfunction ma occur depending on the USB devices connected at an one time.
• When connecting Network Walkman to our computer for the first time, the USB driver Installer window
appears. Please follow the instructions in the Installer window.
• You cannot operate the pla er while it is connected to a computer.
If ou place the pla er on the USB cradle connected to a computer during pla back, pla back stops and "PC"
appears on the displa .
• Even if ou connect the pla er to a computer, it is impossible to browse the contents of the built-in memor
of the pla er using the Windows Explorer.
3Transfer the music file to Network Walkman (Check-out).
For details on how to operate, refer to the OpenMG Jukebox Operating Instructions.
Tip
To transfer the song back to the computer (check-in), refer to the OpenMG Jukebox software instruction
manual or the online help.
Note on playing back time-limited music
(timeout contents)
Some music data distributed via the Internet (EMD service) have pla back time restriction.
When ou pla back a song with pla back time restriction, the timeout icon (page 11) goes on.
If ou tr to pla back a song whose pla back period is alread expired, the timeout icon flashes
and pla back of the next song begins.
We recommended ou to check-in or delete the expired song in the pla er to the computer using
the OpenMG Jukebox software.
OpenMG Jukebox will not pla back the expired song and the expired song will not be available
for check-out to Network Walkman. Delete these songs as needed.

Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ωand 1/4W or less unless otherwise
specified.
•: B+ Line.
• Power voltage is dc 1.5V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : PLAY
∗: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
J: DIGITAL
F: ANALOG
• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
form that of conventional IC.
*Replacement of IC601 used in the set requires a special
tool.
