Welcome !

Thank you for purchasing this Sony Compact Disc Player. You can enjoy your drive with the following functions. CD playback You can play CD-DA (also containing CD TEXT*), CD-R/CD-RW (MP3/WMA files also containing Multi Session (page 12)) and ATRAC CD (ATRAC3 and ATRAC3plus format (page 13)).
Type of discs CD-DA Label on the disc
Warning if your cars ignition has no ACC position After turning the ignition off, be sure to press and hold (OFF) on the unit until the display disappears. Otherwise, the display does not turn off and this causes battery drain.
This label is located on the bottom of the chassis. Manufactured under license from BBE Sound, Inc. The BBE MP process improves digitally compressed sound, such as MP3, by restoring and enhancing the higher harmonics lost through compression. BBE MP works by generating even-order harmonics from the source material, effectively recovering warmth, detail and nuance.

MP3 WMA ATRAC CD

Radio reception You can store up to 6 stations per band (FM1, FM2, FM3, AM1 and AM2). BTM (Best Tuning Memory): the unit selects strong signal stations and stores them. Sound adjustment EQ3 parametric: You can choose any one of 7 preset equalizer curves, and adjust as desired. DSO (Dynamic Soundstage Organizer): creates a more ambient sound field, using virtual speaker synthesis, to enhance the sound of speakers, even if they are installed low in the door. BBE MP: improves digitally compressed sound such as MP3. Image setting You can set various display images on the unit.
Space Producer: creates animated on-screen patterns in time with the music.

Adjusting the volume level

MP3, which stands for MPEG-1 Audio Layer-3, is a music file compression format standard. It compresses audio CD data to approximately 1/10 of its original size. WMA, which stands for Windows Media Audio, is another music file compression format standard. It compresses audio CD data to approximately 1/22* of its original size.

* only for 64 kbps

Do not use any discs with labels or stickers attached. The following malfunctions may result from using such discs: Inability to eject a disc (due to a label or sticker peeling off and jamming the eject mechanism). Inability to read audio data correctly (e.g., playback skipping, or no playback) due to heat shrinking of a sticker or label causing a disc to warp. Discs with non-standard shapes (e.g., heart, square, star) cannot be played on this unit. Attempting to do so may damage the unit. Do not use such discs. You cannot play 8 cm CDs.
The unit is compatible with the ISO 9660 level 1/ level 2 format, Joliet/Romeo in the expansion format, and Multi Session. The maximum number of: folders (albums): 150 (including root and empty folders). MP3/WMA files (tracks) and folders contained in a disc: 300 (if a folder/file names contain many characters, this number may become less than 300). displayable characters for a folder/file name is 32 (Joliet), or 64 (Romeo). ID3 tag versions 1.0, 1.1, 2.2, 2.3 and 2.4 apply to MP3 only. ID3 tag is 15/30 characters (1.0 and 1.1), or 63/126 characters (2.2, 2.3 and 2.4). WMA tag is 63 characters.
Playback order of MP3/WMA files

ATRAC CD

ATRAC CD is recorded audio CD data which is compressed to ATRAC3 or ATRAC3plus format using authorized software, such as SonicStage 2.0 or later, or SonicStage Simple Burner. The maximum number of: folders (groups): 255 files (tracks): 999 The characters for a folder/file name and text information written by SonicStage is displayed. For details on ATRAC CD, see the SonicStage or SonicStage Simple Burner manual.
Note Be sure to create the ATRAC CD using authorized software, such as SonicStage 2.0 or later, or SonicStage Simple Burner 1.0 or 1.1.
Notes When naming an MP3 file/WMA file, be sure to add the file extension.mp3/.wma to the file name. During playback of a VBR (variable bit rate) MP3/ WMA file or fast-forward/reverse, elapsed playing time may not display accurately. When the disc is recorded in Multi Session, only the first track of the first session format is recognized and played (any other format is skipped). The priority of the format is CD-DA, ATRAC CD and MP3/WMA. When the first track is a CD-DA, only CD-DA of the first session is played. When the first track is not a CD-DA, an ATRAC CD or MP3/WMA session is played. If the disc has no data in any of these formats, NO Music is displayed. Notes on MP3 Be sure to finalize the disc before using on the unit. If you play a high-bit-rate MP3, such as 320 kbps, sound may be intermittent. Notes on WMA Files made with lossless compression are not playable. Files protected by copyright are not playable.

If you have any questions or problems concerning your unit that are not covered in this manual, consult your nearest Sony dealer.

Maintenance

Replacing the lithium battery of the card remote commander
Under normal conditions, the battery will last approximately 1 year. (The service life may be shorter, depending on the conditions of use.) When the battery becomes weak, the range of the card remote commander becomes shorter. Replace the battery with a new CR2025 lithium battery. Use of any other battery may present a risk of fire or explosion.

About ATRAC CD

ATRAC3plus format

ATRAC3, which stands for Adaptive Transform Acoustic Coding3, is audio compression technology. It compresses audio CD data to approximately 1/10 of its original size. ATRAC3plus, which is an extended format of ATRAC3, compresses the audio CD data to approximately 1/20 of its original size. The unit accepts both ATRAC3 and ATRAC3plus format.
Notes on the lithium battery Keep the lithium battery out of the reach of children. Should the battery be swallowed, immediately consult a doctor. Wipe the battery with a dry cloth to assure a good contact. Be sure to observe the correct polarity when installing the battery. Do not hold the battery with metallic tweezers, otherwise a short-circuit may occur.

WARNING

Battery may explode if mistreated. Do not recharge, disassemble, or dispose of in fire.

Fuse replacement

When replacing the fuse, be sure to use one matching the amperage rating stated on the original fuse. If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer.
