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 CXD9644GG (IC710) 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.

Transferring songs from the computer to
Network Walkman (Check-out)
In order to check out digital audio files from your computer, first you must install the supplied
OpenMG Jukebox software and then import digital audio files to OpenMG Jukebox.
For details, refer to the OpenMG Jukebox operating Instructions.
1onnect Network Walkman to your computer
onnect the narrow connector of the supplied dedicated USB cable into the dedicated USB jack on
Network Walkman, then the wide connector to the USB jack of your computer.
“ ONNE T” appears in the display.
Notes
• Do not connect more than two USB devices (player) to your computer. Normal operation will not be
guaranteed.
• If you use this player with a USB hub or a USB extension cable normal operation is not guaranteed.
• A malfunction may occur depending on the USB devices connected at any one time.
• Be sure to insert a fresh Alkaline battery into the unit. If the battery is not inserted, or battery power is
exhausted, the unit will not be identified by the computer.
• When connecting Network Walkman to your computer for the first time, the USB driver Installer window
appears. Please follow the instructions in the Installer window.
• onnect Network Walkman only as necessary. Disconnect the dedicated USB cable when not needed.
2Transfer the music file to Network Walkman ( heck-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.

1 Putting the player on your ears
continued
Notes
• Please remove earrings.
• If you wear the glasses, remove your glasses before
putting on this player and put them on again.
• Be sure not to open the attaching part more than
2 cm. Otherwise, this player may deform and
might not sit on your ears comfortably. Note that
if you press the player to opposite side, it also
may deform.
1Pinch the center of
the player with your
thumb and middle
finger, and then open
the attaching part
with your forefinger.
2Hook the cured part
around the back of your
ear and twist it to the
earlobe direction to sit it
on your ear. If your hair
hangs over your ear,
please push back your
hair before attaching it.
3Adjust the position of
the player to fix it
comfortably.
If you cannot attach the player to your ear comfortably
onfirm the position of the player with a mirror. In the correct position, your ears should appear as
illustrated. if your ears are small and not visible as shown, use the supplied attachments (see page 15).
To remove the player from your ears
Twist the player to the opposite direction when attaching it, and remove it.
The attaching
part of this player
would be open
(be apart)
flexibly.
