- Main feature

1. The lightness in industry^{- Achievement of compact body of one}

*** It is the lightest in the industry because of further lightening of the mechanism parts. adopt the high rigidity magnesium in a main body upper and lower cabinet^{- A small size of about 49g of one} (Only the main body :) and the thinness about 12.5mm(The projection part does not contain it) is achieved. "Portability" which was an important element as a portable equipment was persisting pursued.

2. Longest in industry^{- A continuous reproduction of two} of about 145 hours is achieved.

The longest in the industry because of making of an electric circuit by the optimization of the supply voltage to adoption of a highly effective motor, further development of LSI in a low voltage, and each IC etc. thorough a conserve electric power. ^{- [It] continuous reproduces and about 145 hours of two} are achieved. (The attached charge pond, [it] used together one Sony alkali AA dry battery, and the LP4 mode reproduced) The continuous reproduction time was postponed for about as many as 45 hours compared with our company MD Walkman “MZ-E900" (sale on September 10, 2000). The music life in outdoor can be enjoyed as the battery cutting does not worry.

3. For MD "Stereo mode (MDLP) and function of group for a long time"

[It] corresponds to the disk to which the group is set by using the MDLP function to say nothing of the disk to which the stereo was recorded for a long time. A lot of recorded tunes can be easily selected by using functions such as "Group mode reproduction" and "Group skip".

4. New stick controller attachment of Chinese character display correspondence

The title input by the Chinese character in addition to the Japanese syllabary and the British number character can be displayed. The backing light addition and the number of character displays is the em-size six character displays to the liquid crystal display part. The thickness of the entire remote control is improved by arranging headphone Jack in the head and the installation feeling with the pressing clip has been improved. ON/OFF of the group mode and the group can skip easily at hand corresponding to the group function.

5. Equipped with 音飛び(unknown word) guard function “G-PROTECTION" ((*jiipurotekushon*))

Efficient 音飛び(unknown word) guard mechanism “G-PROTECTION" which Sony developed is installed aiming at "音飛び(unknown word) 0". Jumping, and worry is hardly, and can enjoy music pleasantly as for sound even if keeping shaking while out for a long time because (*S) deals corresponding to shake and vibration in every case momentarily

6. DSP TYPE-R adoption for new development ATRAC

[It] corresponds to DSP TYPE-R for new development ATRAC installed in high spec MD deck of Sony and recording MD Walkman “MZ-R909" (sale schedule on August 21, 2001), etc.If the disk to which the SP stereo was recorded by “TYPE-R" is reproduced, abundant music “TYPE-R" original tone quality can be reproduced.

7. "Charge stand" attachment which can be easily charged only by putting it

*** Equipped with "知(unknown word) らせ(unknown word) <leaving> LED of the color of three" <8. the state of the group control and the amount of the battery remainder> <understanding>.

State of ON/OFF of "Group function" and "Amount of the battery remainder" are understood from lighting and blinking of LED installed on the part operation side on the main body to three colors (red, green, and orange) in one glance.

9. Other features

- Equipped with "Index search function" in remote control by which retrieval of quick tune is enabled

- Equipped with "(*wantatchiijekt*) mechanism" that putting disk in and out is easy

- Equipped with "Personal disk memory" by which setting my inclination is memorized

- Equipped with "(*dejitarusaundopuriset*) function" which can be customized to tone quality of my specification

- Equipped with "Speed control function" which can be reproduced by tempo of favor

- Equipped with "Melody timer" of which [it] informs at specified time

- Equipped with 16 pattern play mode by which various hows to listen can be enjoyed on one disk
