Advanced Operations
Storing non-audio
data
You can transfer data from the hard disk of your
computer to the built-in flash memory using
Windows Explorer.
The built-in flash memory is displayed in
Windows Explorer as an external drive (for
example: as the D drive).
Notes
• You cannot operate the SonicStage software while
operating the data storage function of your Network
Walkman to use files stored in the built-in flash
memory. The error message “Cannot access the Device/
media.” will be displayed when you try to operate both
of them simultaneously.
• If you store a lot of non-audio data into the built-in
flash memory, the space for audio data is reduced by
the same amount.

Precautions
On installation
Never use your Network Walkman where it will
be subjected to extremes of light, temperature,
moisture or vibration.
On the headphones
Road Safety
Do not use headphones while driving, cycling, or
operating any motorized vehicle. It may create a
traffic hazard and is illegal in many areas. It can
also be potentially dangerous to play your
Network Walkman at a high volume while
walking, especially at pedestrian crossings. You
should exercise extreme caution or discontinue
use in potentially hazardous situations.
Preventing hearing damage
Avoid using the headphones at a high volume.
Hearing experts advise against continuous, loud
and extended play. If you experience a ringing in
your ears, reduce the volume or discontinue use.
Caring for others
Keep the volume at a moderate level. This will
allow you to hear outside sounds and to be
considerate to the people around you.
Warning
If there is lightning when you are using your
Network Walkman, take off the headphones
immediately.
On cleaning
• Clean your Network Walkman casing with a soft
cloth slightly moistened with water or a mild
detergent solution.
• Clean the headphone plug periodically.
Note
Do not use any type of abrasive pad, scouring powder or
solvent such as alcohol or benzene as it may mar the
finish of the casing.
If you have any questions or problems concerning
your Network Walkman, please consult your
nearest Sony dealer.

30

Glossary
MagicGate
Copyright protection technology that consists of authentication and encryption technology. Authentication
ensures that protected content is transferred only between compliant devices and media, and that protected
content is recorded and transferred in an encrypted format to prevent unauthorized copying or playback.
Note
is terminology denoting the copyright protection system developed by Sony. It does not guarantee
conversion among other media.
OpenMG
Copyright protection technology that securely manages music content from the EMD/Audio CD on a
personal computer. Application software that is installed on the computer encrypts the digital music content
when recording on the hard drive. This allows you to enjoy music content on the computer, but prevents
unauthorized transmission of this content across a network (or elsewhere). This PC copyright protection
complies with “MagicGate”, and allows you to transfer digital music content from a PC’s hard drive to a
compliant device.
SonicStage
Copyright protection technology that securely manages music content from the EMD/Audio CD on a
personal computer. Application software that is installed on the computer encrypts the digital music content
when recording on the hard drive. This allows you to enjoy music content on the computer, but prevents
unauthorized transmission of this content across a network (or elsewhere). This PC copyright protection
complies with “MagicGate”, and allows you to transfer digital music content from a computer’s hard disk
to a compliant device.
ATRAC3
ATRAC3, which stands for Adaptive Transform Acoustic Coding3, is audio compression technology that
satisfies the demand for high sound quality and high compression rates.
The ATRAC3 compression rate is approximately 10 times higher than that of the Audio CD, resulting in an
increased data capacity for the media.
ATRAC3plus
ATRAC3plus, which stands for Adaptive Transform Acoustic Coding3plus, is audio compression
technology that compresses data higher than ATRAC3. The ATRAC3plus is new audio compression
technology that enables equal or higher quality sound comparing to ATRAC3.
Bit rate
Indicates the data amount per second. The rate is reflected in bps (bit per second).
64 kbps means 64000 bits of information per second. If the bit rate is large, that means a large amount of
information is used to play music. Comparing music of the same format (e,g., ATRAC3plus), 64 kbps data
offers better sound quality than 48 kbps data. However, audio files in formats such as MP3 have different
encoding methods, and thus sound quality cannot be determined by simply comparing the bit rate.
