Discs that this system cannot play back

• CD-ROMs other than those has MP3 audio tracks that conforms to ISO 9660 ^a) Level 1, Level 2, Joliet in expansion format.
• CD-Rs/CD-RWs other than those recorded in the following formats:

- audio CD format

- MP3 audio track format that conforms to ISO 9660 ^a) Level 1, Level 2, Joliet in expansion format or Multi Session ^b) .

• Data part of CD-Extras ^c) .
• Data part of Mixed CDs ^d) .
- A disc that has a non-standard shape (e.g., card, heart).
• A disc with paper or stickers on it.
- A disc that has the adhesive, cellophane tape, or a sticker still left on it.
• Audio side of a DualDisc.

a) ISO 9660 Format

The most common international standard for the logical format of files and folders on a CD-ROM. There are several specification levels. In Level 1, file names must be in the 8.3 format (no more than eight characters in the name, no more than three characters in the extension “.MP3”) and in capital letters. Folder names can be no longer than eight characters. There can be no more than eight nested folder levels. Level 2 specifications allow file names and folder names up to 31 characters long. Each folder can have up to 8 trees.

b) Multi Session

This is a recording method that enables adding of data using the Track-At-Once method. Conventional discs begin at a disc control area called the Lead-in and end at an area called Lead-out. A Multi Session disc is a disc having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session.

c) CD-Extra

This format records audio (audio CD data) on the tracks in session 1 and data on the tracks in session 2.

d) Mixed CD

This format records data on the first track and audio (audio CD data) on the second and subsequent tracks of a session.

Notes on discs

• This system can play back CD-R/CD-RW discs edited by the user. However, note that playback of some discs may not be possible depending on the recording device used for recording or the disc condition.
• Discs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition or the driver's characteristics.
• CD-R and CD-RW discs that have not been correctly finalized (processing to allow play back by a normal CD player) cannot be played back.
• CD-R and CD-RW discs recorded in multi-session that have not ended by “closing the session” are not supported.
• The system may be unable to play back MP3 format files that do not have the extension “.MP3”.
• Attempting to play back non-MP3 format files that have the extension “.MP3” may result in noise or malfunction.
• The system can play back to a depth of 8 folders only.
• With formats other than ISO 9660 level 1, level 2 or Joliet in expansion format, folder names or file names may not be displayed correctly.
• The following discs take a longer time to start playback.
• a disc recorded with complicated tree structure.
• a disc recorded in Multi Session.
• a disc to which data can be added (non-finalized disc).
• A disc recorded in packet write format cannot be played back.

Note on DualDiscs

This product is designed to play back discs that conform to the Compact Disc (CD) standard. A DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other side. Please be aware that the audio side of a DualDisc may not be played back on this product because these discs do not conform to the CD standard. "DualDisc" is a trademark of the Recording Industry Association of America (RIAA).

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.

Cautions when playing a disc that is recorded in Multi Session

• This system can play back Multi Session discs when an MP3 audio track is contained in the first session. Any subsequent MP3 audio tracks recorded in later sessions can also be played back.
• When you play back Multi Session discs with different formats for each session, the format of the first session is recognized as the disc type. Tracks in the second and subsequent sessions are played back if they are the same formats as the first session.

Additional Information

Precautions

On operating voltage

Before operating the system, check that the operating voltage of your system is identical with the voltage of your local power supply.

On safety

• The system is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the system itself has been turned off.
• Unplug the system from the wall outlet (mains) if it is not to be used for an extended period of time. To disconnect the power cord (mains lead), pull it out by the plug. Never pull the cord itself.
• Should any solid object or liquid fall into the system, unplug the system and have it checked by qualified personnel before operating it any further.
• For customers in United States
  One blade of the plug is wider than other for the purpose of safety and will fit to the wall outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer.
• AC power cord must be changed only at the qualified service shop.

On placement

- Do not place the system in an inclined position.

- Do not place the system in locations where it is;

• Extremely hot or cold
  – Dusty or dirty
• Very humid
  – Subject to vibrations
  – Subject to direct sunlight

- Use caution when placing the system or speakers on surfaces that have been specially treated (with wax, oil, polish, etc.) as staining or discoloration of the surface may result.

On heat build-up

• Although the system heats up during operation, this is not a malfunction.
• Place the system in a location with adequate ventilation to prevent heat build-up in the system.
• If you continuously use this system at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet.
• To prevent a malfunction, do not cover the ventilation hole for the cooling fan.

On operation

- If the system is brought directly from a cold to a warm location, or is placed in a very damp room, moisture may condense on the lens inside the system. Should this occur, the system will not operate properly. Remove the disc and leave the system turned on for about an hour until the moisture evaporates.

- When you move the system, take out any disc.

If you have any questions or problems concerning your system, please consult your nearest Sony dealer.

Notes on discs

• Before playing, clean the disc with a cleaning cloth. Wipe the disc from the center out.
• Do not use solvents such as benzene, thinner, commercially available cleaners or anti-static spray intended for vinyl LPs.
• Do not expose the disc to direct sunlight or heat sources such as hot air ducts nor leave it in a car parked in direct sunlight.
• Do not use discs encircled with a protection ring. This may cause a malfunction to the system.
• When using discs that have glue or similar tacky substance on the label side of the disc or that used a special ink when the label was printed, there is a chance that the disc or label may become attached to parts inside this system. When this occurs, it may not be possible to remove the disc, and may also cause this system to malfunction. Be sure to check that the label side of the disc is not sticky before using. The following types of disc should not be used:
  – Rental or used discs with attached seals where the glue extends beyond the seal. The perimeter of the seal on the disc is tacky.
  – Discs that have labels printed using a special ink that feels tacky when touched.
• Discs with non-standard shapes (e.g., heart, square, star) cannot be played back on this system.
  Attempting to do so may damage the system. Do not use such discs.

Cleaning the cabinet

Clean the cabinet, panel and controls with a soft cloth slightly moistened with mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as thinner, benzene or alcohol.

To save a tape permanently

To prevent a tape from being accidentally recorded over, break off the tape tab from side A or B as illustrated.

Break off the tape tab

Diagram showing a submerged object with a curved arrow indicating motion or force (no text or symbols)

If you later want to reuse the tape for recording, cover the broken tab with adhesive tape.

Before placing a tape in the tape deck

Take up any slack in the tape deck. Otherwise, the tape may get entangled in the parts of the tape deck and become damaged.

When using a tape longer than 90 minutes

The tape is very elastic. Do not change the tape operations such as playback, stop and fast-winding etc. frequently. The tape may get entangled in the tape deck.

Cleaning the tape heads

Clean the tape heads after every 10 hours of use. Be sure to clean the tape heads before you start an important recording or after playing an old tape. Use a separately sold dry-type or wet-type cleaning tape. For details, refer to the instructions of the cleaning tape.

Demagnetizing the tape heads

Demagnetize the tape heads and the metal parts that have contact with the tape after every 20 to 30 hours of use with a separately sold demagnetizing tape. For details, refer to the instructions of the demagnetizing tape.
