WEATHER, FINANCE, CHILDREN,  
SOCIAL, RELIGION, PHONE IN, TRAVEL,  
LEISURE, JAZZ, COUNTRY (country music),  
NATION M (nations popular music),  
OLDIES, FOLK M, DOCUMENT

in is not transmitting the RDS signal properly or if the  
signal is weak.  
(investigative features), TEST (test signal for  
emergency broadcast), ALARM (emergency  
broadcast) and NONE (any programs not  
defined above).

Additional Information  
Precautions  
Cleaning the cabinet  
Use a soft cloth slightly moistened with mild  
detergent solution.  
To save a tape permanently  
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.  
To prevent a tape from being accidentally recorded  
over, break off the cassette tab from side A or B as  
illustrated. If you later want to reuse the tape for  
recording, cover the broken tab with adhesive tape.  
On safety  
• 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 system from the wall outlet (mains) if it  
is not to be used for an extended period of time. To  
disconnect the cord (mains lead), pull it out by the  
plug. Never pull the cord itself.  
Tab of side B  
Tab of side A  
• Should any solid object or liquid fall into the  
component, unplug the system and have it checked  
by qualified personnel before operating it any  
further.  
• The AC power cord must be changed only at a  
qualified service shop.  
Break off  
the cassette  
tab of side A  
On placement  
• Place the system in a location with adequate  
ventilation to prevent heat build up.  
• Do not place the system in an inclined position.  
• Do not place the system in locations where it is:  
— Extremely hot or cold  
Before placing a cassette in the tape  
deck  
Take up any slack in the tape. Otherwise the tape may  
get entangled in the parts of the tape deck and become  
damaged.  
— Dusty or dirty  
— Very humid  
— Subject to vibrations  
— Subject to direct sunlight.  
When using a tape longer than 90  
minutes  
The tape is very elastic. Do not change the tape  
operations such as play, stop, and fast-winding  
frequently. The tape may get entangled in the tape  
deck.  
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 CD  
player. Should this occur, the system will not  
operate properly. Remove the CD and leave the  
system turned on for about an hour until the  
moisture evaporates.  
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  
cassette. For details, refer to the instructions of the  
cleaning cassette.  
• When you move the system, take out any discs.  
If you have any questions or problems concerning  
your stereo system, please consult your nearest Sony  
dealer.  
Demagnetizing the tape heads  
Demagnetize the tape heads and the metal parts that  
have contact with the tape every 20 to 30 hours of use  
with a separately sold demagnetizing cassette. For  
details, refer to the instructions of the demagnetizing  
cassette.  
Notes on CDs  
• Before playing, clean the CD with a cleaning cloth.  
Wipe the CD from the center out.  
• Do not use solvents.  
• Do not expose the CD to direct sunlight or heat  
sources.  
Note on CD-R playback  
Discs recorded on CD-R drives may not be played  
back because of scratches, dirt, recording condition or  
the drive’s characteristics. Besides, the discs, which  
are not yet finalized at the end of recording, cannot be  
played back.
