Before playing, clean the discs with a commercially available cleaning cloth. Wipe each disc from the center out. Do not use solvents such as benzine, thinner, commercially available cleaners, or antistatic spray intended for analog discs.
Playback order of MP3/WMA/AAC files
MP3/WMA/AAC Folder (album) MP3/WMA/ AAC file (track)
Notes on CD-R/CD-RW discs
Some CD-Rs/CD-RWs (depending on the equipment used for its recording or the condition of the disc) may not play on this unit. You cannot play a CD-R/a CD-RW that is not finalized. 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). 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). 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 and MP3/WMA/AAC. 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, the MP3/ WMA/AAC session is played. If the disc has no data in any of these formats, NO Music is displayed.

About MP3 files

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. 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). When naming an MP3 file, be sure to add the file extension.mp3 to the file name. During playback or fast-forward/reverse of a VBR (variable bit rate) MP3 file, elapsed playing time may not display accurately.

Note If you play a high-bit-rate MP3, such as 320 kbps, sound may be intermittent.
Music discs encoded with copyright protection technologies
This product is designed to play back discs that conform to the Compact Disc (CD) standard. Recently, various music discs encoded with copyright protection technologies are marketed by some record companies. Please be aware that among those discs, there are some that do not conform to the CD standard and may not be playable by this product.

About WMA files

WMA, which stands for Windows Media Audio, is a music file compression format standard. It compresses audio CD data to approximately 1/22* of its original size. WMA tag is 63 characters. When naming a WMA file, be sure to add the file extension.wma to the file name. During playback or fast-forward/reverse of a VBR (variable bit rate) WMA file, elapsed playing time may not display accurately.
* only for 64 kbps Note Playback of a lossless compression file is not supported.

Note on DualDiscs

A DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other side. However, since the audio material side does not conform to the Compact Disc (CD) standard, playback on this product is not guaranteed.

About AAC files

AAC, which stands for Advanced Audio Coding, is a music file compression format standard. It compresses audio CD data to approximately 1/11* of its original size. AAC tag is 126 characters. When naming an AAC file, be sure to add the file extension.m4a to the file name. During playback or fast-forward/reverse of a VBR (variable bit rate) AAC file, elapsed playing time may not display accurately.
* only for 128 kbps Note Playback of the following AAC files is not supported. lossless compression copyright-protected

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.

Fuse (10 A)

Cleaning the connectors
The unit may not function properly if the connectors between the unit and the front panel are not clean. In order to prevent this, detach the front panel (page 5) and clean the connectors with a cotton swab. Do not apply too much force. Otherwise, the connectors may be damaged.
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.
+ side up Back of the front panel Notes For safety, turn off the ignition before cleaning the connectors, and remove the key from the ignition switch. Never touch the connectors directly with your fingers or with any metal device.
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.

Removing the unit

Remove the protection collar. 1 Detach the front panel (page 5). 2 Pinch both edges of the protection collar, then pull it out.

Cautions
This unit is designed for negative ground (earth) 12 V DC operation only. Do not get the leads under a screw, or caught in moving parts (e.g. seat railing). Before making connections, turn the car ignition off to avoid short circuits. Connect the yellow and red power supply leads only after all other leads have been connected. Run all ground (earth) leads to a common ground (earth) point. Be sure to insulate any loose unconnected leads with electrical tape for safety. The use of optical instruments with this product will increase eye hazard. Notes on the power supply lead (yellow) When connecting this unit in combination with other stereo components, the connected car circuits rating must be higher than the sum of each components fuse. When no car circuits are rated high enough, connect the unit directly to the battery.

Connection example

Notes (-A) Be sure to connect the ground (earth) lead before connecting the amplier. The alarm will only sound if the built-in amplier is used. Tip (-B- ) For connecting two or more CD/MD changers, the source selector XA-C40 (not supplied) is necessary.
Notes on the control and power supply leads The power antenna (aerial) control lead (blue) supplies +12 V DC when you turn on the tuner. When your car has built-in FM/AM antenna (aerial) in the rear/ side glass, connect the power antenna (aerial) control lead (blue) or the accessory power supply lead (red) to the power terminal of the existing antenna (aerial) booster. For details, consult your dealer. A power antenna (aerial) without a relay box cannot be used with this unit. Memory hold connection When the yellow power supply lead is connected, power will always be supplied to the memory circuit even when the ignition switch is turned off. Notes on speaker connection Before connecting the speakers, turn the unit off. Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities to avoid its damage. Do not connect the speaker terminals to the car chassis, or connect the terminals of the right speakers with those of the left speaker. Do not connect the ground (earth) lead of this unit to the negative () terminal of the speaker. Do not attempt to connect the speakers in parallel. Connect only passive speakers. Connecting active speakers (with built-in ampliers) to the speaker terminals may damage the unit. To avoid a malfunction, do not use the built-in speaker leads installed in your car if the unit shares a common negative () lead for the right and left speakers. Do not connect the units speaker leads to each other. Note on connection If speaker and amplier are not connected correctly, FAILURE appears in the display. In this case, make sure the speaker and amplier are connected correctly.
