Precautions

Discs that this unit CAN play

 Audio CD

 CD-R/CD-RW (CD-DA*/MP3/WMA files)

* CD-DA is the abbreviation for Compact Disc Digital Audio. It is a 

recording standard used for Audio CDs.

Discs that this unit CANNOT play

 CD-R/CD-RW other than those recorded in music CD 

format, WMA format and MP3 format conforming to 

ISO9660 Level 1/Level 2 or Joliet

 CD-R/CD-RW of poor recording quality, CD-R/CD-RW 

that has scratches or is dirty, or CD-R/CD-RW recorded 

with an incompatible recording device

 CD-R/CD-RW which is incorrectly finalized

Notes on discs

 Before playing, clean the CD with a cleaning cloth. 

Wipe the CD from the center out. If there is a scratch, 

dirt or fingerprints on the CD, it may cause a tracking 

error.

 Do not use solvents such as benzine, thinner, 

commercially available cleaners or anti-static spray 

intended for vinyl LPs.

 Do not expose the CD to direct sunlight or heat sources 

such as hot air ducts, nor leave it in a car parked in 

direct sunlight as there can be a considerable rise in 

temperature inside the car.

 Do not stick paper or stickers on the CD, nor scratch 

the surface of the CD.

 After playing, store the CD in its case.

On safety

 As the laser beam used in the CD player is harmful to 

the eyes, do not attempt to disassemble the casing. 

Refer servicing to qualified personnel only.

 Should any solid object or liquid fall into the unit, 

unplug the unit, and have it checked by qualified 

personnel before operating it any further.

 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.

On power sources

 For AC operation, check that the unit’s operating 

voltage is identical with your local power supply (see 

“Specifications”) and use the supplied AC power cord; 

do not use any other type. 

 The unit is not disconnected from the AC power source 

(mains) as long as it is connected to the wall outlet, 

even if the unit itself has been turned off.

 Unplug the unit from the wall outlet when it is not used 

for an extended period of time.

 When the batteries are not to be used, remove them to 

avoid damage that can be caused by battery leakage or 

corrosion.

 The nameplate and important information concerning 

safety are located on the bottom exterior.

On placement

 Do not leave the unit in a location near heat sources, in 

a place subject to direct sunlight, excessive dust or 

mechanical shock, or in a car subject to the direct rays 

of the sun.

 Do not place the unit on an inclined or unstable place.

 Do not place anything within 10 mm of the side of the 

cabinet. The ventilation holes must be unobstructed for 

the unit to operate properly and prolong the life of its 

components.

 Since a strong magnet is used for the speakers, keep 

personal credit cards using magnetic coding or spring-

wound watches away from the unit to prevent possible 

damage from the magnet.

On operation

 If the unit 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 CD player. Should 

this occur, the unit will not operate properly. In this 

case, remove the CD and wait about an hour for the 

moisture to evaporate.

Cleaning the cabinet

 Clean the cabinet, panel and controls with a soft cloth 

slightly moistened with a mild detergent solution. Do 

not use any type of abrasive pad, scouring powder, or 

solvent, such as alcohol or benzine.

If you have any questions or problems concerning your 

unit, please consult your nearest Sony dealer.
