Before playing, clean the CD with

a cleaning cloth. Wipe the CD

from the center out. If there are



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, or 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 a sticker on the CD, or

scratch the surface of the CD.



After playing, store the CD in its case.

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.

Tab for side B

Tab for side A



The use of a cassette tape with more than

90minutes of play time is not recommended

except for long, continuous recording or

playback.

On safety



As the laser beam used in the CD player

section is harmful to 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, use the supplied AC power

cord; do not use any other cord.



Unplug the unit from the wall outlet if it is not

to be used for an extended period of time.



When not using the batteries, remove them to

avoid damage that can be caused by battery

leakage or corrosion.

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 surface.



Do not place anything within 10 mm of the rear

of the cabinet. The ventilation openings 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 section. 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.

On handling the unit



Do not leave the CD compartment open to

avoid dust and debris contamination.

On cleaning the cabinet



Clean the cabinet, panel and controls using 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, consult your nearest Sony

dealer.
