SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS

AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB- LISHED BY SONY.

Other features

•Compact size, light weight.

•Skip-proof: you can enjoy uninterrupted enjoyment of music during physical activities such as jogging or commuting.

•Approximately 4 hours of continuous playback with a rechargeable nickel-cadmium battery. •Recordable time: up to 30 min., 40 min., 60 min.**, on the supplied 32MB “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.

*The copyright protection technology of Network Walkman conforms to the SDMI (Secure Digital Music Initiative) specifications.

**Differs according to the bit rate when recording. In this case, the figures for the recordable time are when recording on a 32MB “MagicGate Memory Stick” at 132kbps, 105kbps, and 66kbps.

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.

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.
