Additional Information  
Precautions  
On safety  
On placement  
• As the laser beam used in the CD  
player section is harmful to the eyes,  
do not attempt to disassemble the  
casing. Refer servicing to qualified  
personnel only.  
• Do not leave the player in a location  
near heat sources, or in a place subject  
to direct sunlight, excessive dust or  
mechanical shock.  
• Do not place the player on an inclined  
or unstable place.  
• Should any solid object or liquid fall  
into the player, unplug the player, and  
have it checked by qualified personnel  
before operating it any further.  
• Do not place anything within 10 mm  
of the side of the cabinet. The  
ventilation holes must be  
unobstructed for the player to operate  
properly and prolong the life of its  
components.  
On power sources  
• For AC operation, use the supplied  
AC power cord; do not use any other  
type.  
• If the player is left in a car parked in  
the sun, be sure to choose a location in  
the car where the player will not be  
subjected to the direct rays of the sun.  
• The player is not disconnected from  
the AC power source (mains) as long  
as it is connected to the wall outlet,  
even if the player itself has been  
turned off.  
• Since a strong magnet is used for the  
speakers, keep personal credit cards  
using magnetic coding or spring-  
wound watches away from the player  
to prevent possible damage from the  
magnet.  
• Unplug the player from the wall outlet  
when it is not to be used for an  
extended period of time.  
• For battery operation, use six size D  
(R20) batteries.  
On operation  
• If the player is brought directly from a  
cold to a warm location, or is placed in  
a very damp room, moisture may  
condense on the lenses inside the CD  
player section. Should this occur, the  
player will not operate properly. In  
this case, remove the CD and wait  
about an hour for the moisture to  
evaporate.  
• When the batteries are not to be used,  
remove them to avoid damage that  
can be caused by battery leakage or  
corrosion.  
• The nameplate indicating operating  
voltage, power consumption, etc. is  
located at the bottom.  
• If the player has not been used for a  
long time, set it in the playback mode  
to warm it up for a few minutes before  
inserting a cassette.  
If you have any questions or problems  
concerning your player, please consult  
your nearest Sony dealer.

Notes on CDs  
Notes on cassettes  
• Before playing, clean the CD with a  
cleaning cloth. Wipe the CD from the  
center out.  
• Break off the cassette tab from side A  
or B to prevent accidental recording. If  
you want to reuse the tape for  
recording, cover the broken tab with  
adhesive tape.  
Side A  
Tab for side A  
Tab for side B  
• Do not use solvents such as benzine,  
thinner, commercially available  
cleaners or anti-static spray intended  
for vinyl LPs.  
• To record on a tape with its tab broken  
off, cover the respective tab hole for  
side A or B with adhesive tape.  
• 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.  
• The use of a cassette with more than  
90 minutes of play time is not  
recommended except for long,  
continuous recording or playback.  
• Do not stick paper or sticker on the  
CD, nor scratch the surface of the CD.  
• After playing, store the CD in its case.  
If there is a scratch, dirt or fingerprints  
on the CD, it may cause tracking error.

Maintenance  
Cleaning the lens  
Demagnetizing the tape heads  
If the lens becomes dirty, it may cause a  
skipping of sound during CD operation.  
Clean with a commercially available  
blower.  
After 20 to 30 hours of use, enough  
residual magnetism will have built up  
on the tape heads to begin to cause loss  
of high frequency sound and hiss. At  
this time, you should demagnetize the  
heads and all metal parts in the tape  
path with a commercially available tape  
head demagnetizer.  
Cleaning the tape heads and tape  
path  
Wipe the heads, the pinch roller and the  
capstan with a cleaning swab slightly  
moistened with cleaning fluid or alcohol  
after every 10 hours of operation for  
optimum playback and recording  
quality. To make the best possible  
recording, however, we recommend that  
you clean all surfaces over which tape  
travels before each recording.  
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.
