Warning

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/ TV technician for help. You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment.
*1 You can connect MD changers, CD changers, MD players, or CD players. *2 A CD TEXT disc is an audio CD that includes information such as the disc name, artist name and track names. This information is recorded on the disc.

Precautions

If your car was parked in direct sunlight resulting in a considerable rise in temperature inside the car, allow the unit to cool off before operating it. If no power is being supplied to the unit, check the connections first. If everything is in order, check the fuse. If your car is equipped with a power antenna, it will extend automatically while the unit is operating. Do not use the Custom file feature while driving, or perform any other function which could divert your attention from the road. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.

Moisture Condensation

On a rainy day or in a very damp area, moisture may condense on the lenses inside the unit. Should this occur, the unit will not operate properly. In such a case, remove the disc and wait for about an hour until the moisture has evaporated.

CAUTION

The use of optical instruments with this product will increase eye hazard.
To maintain high quality sound
If you have drink holders near your audio equipment, be careful not to splash juice or other soft drinks onto the unit and MD. Sugary residues on the unit or MD may contaminate the lenses inside the unit, reduce the sound quality, or prevent sound reproduction altogether.

Welcome !

Thank you for purchasing the Sony MiniDisc Player. This unit lets you enjoy a variety of features using the following controller accessories: Optional accessories Rotary commander RM-X4S Card remote commander RM-X91 In addition to the MD playback and radio operations, you can expand your system by connecting optional CD/MD units*1. When you operate this unit or a connected optional CD unit with the CD TEXT function, the CD TEXT information will appear in the display when you play a CD TEXT disc*2.

Notes on MDs

Since the disc itself is housed in a cartridge, free from accidental contact with your fingers and dust, MDs can withstand a certain degree of the rough handling. However, dirt or dust on the surface of the cartridge or a warped cartridge may cause a malfunction. Observe the following for best results. Never touch the surface of the disc itself by deliberately opening the shutter on the cartridge. When you eject the MD, the shutter may be open. In such a case, close the shutter immediately.
Notes on attaching labels
Be sure to attach labels on cartridges correctly, as failing to do so may cause the MD to become stuck in the unit. Attach the label in a suitable position. Remove old labels before putting new ones on. Replace labels that are beginning to peel away from the MD.
Do not expose the MD to direct sunlight or heat sources such as hot air-ducts. Do not leave it in a car parked in direct sunlight where there can a considerable rise in temperature. Make sure the MD is not left on the dashboard or rear tray of a car, etc. where the temperature can also be excessive.

Notes on 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.

2-3. Electrical Parts List
NOTE: Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. -XX and -X mean standardized parts, so they may have some difference from the original one. RESISTORS All resistors are in ohms. METAL:Metal-film resistor. METAL OXIDE: Metal oxide-film resistor. F:nonflammable Items marked * are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. SEMICONDUCTORS In each case, u : , for example: uA. : A. uPA. : PA. uPB. : PB. uPC. : PC. uPD. : PD. CAPACITORS uF : F COILS uH : H Abbreviation CND : Canadian model

When indicating parts by reference number, please include the board.
