Troubleshooting  
1 Make sure the power cord and  
speaker cords are correctly and  
firmly connected.  
• Connect only the supplied speakers.  
Severe hum or noise.  
• Move the system away from sources of  
noise.  
• Connect the system to a different wall  
socket.  
• Install a noise filter (available  
separately) to the power cord.  
• Turn off the surrounding electrical  
equipment.  
2 Find your problem in the checklist  
below, and take the indicated  
corrective action.  
If the problem persists, contact your  
nearest Sony dealer.  
Note that if service personnel changes  
some parts during repair, these parts  
may be retained.  
The remote does not function.  
• Remove any obstacles between the  
remote and the remote sensor on the  
unit, and position the unit away from  
fluorescent lights.  
If the STANDBY indicator flashes  
Immediately unplug the power cord,  
and check the following items.  
• If your system has a voltage selector,  
is the voltage selector set to the  
correct voltage?  
• Point the remote at the system’s sensor.  
• Move the remote closer to the system.  
CD/MP3 player  
• Are you using only the supplied  
speakers?  
The sound skips, or the disc will not  
play.  
• Is anything blocking the ventilation  
holes on the back of the unit?  
After checking the above items and  
fixing any problems, plug in the power  
cord again and turn on the system. If  
the STANDBY indicator still flashes,  
or if the cause of the problem cannot  
be found even after checking all the  
above items, consult your nearest  
Sony dealer.  
• Wipe the disc clean.  
• Move the system to a location away  
from vibration (for example, on top of a  
stable stand).  
• Move the speakers away from the unit,  
or place them on separate stands. At  
high volume, speaker vibration may  
cause the sound to skip.  
Play does not start from the first  
track.  
• Press PLAY MODE repeatedly until  
both “PGM” and “SHUF” light off in  
the display to return to normal play.

NO TRACK: No playable file is loaded  
in the system.  
NOT IN USE: You tried to perform a  
specific operation under conditions  
where that operation is prohibited.  
NOT SUPPORTED: An unsupported  
USB device is connected, or the USB  
device is connected to this system  
through a hub.  
OVER CURRENT: An over current was  
detected.  
• Discs that have adhesive tape, paper, or  
sticker attached to them  
PROTECTED: The USB device is write-  
• Rental or used discs with attached seals where  
the glue extends beyond the seal  
• Discs that have labels printed using ink that  
feels tacky when touched  
protected.  
PUSH STOP: You tried to perform an  
operation that can be performed only  
when the system is stopped.  
Notes on discs  
• Before playing, wipe the disc with a cleaning  
cloth from the center out to the edge.  
• Do not clean discs with solvents, such as  
benzine thinner, or commercially available  
cleaners or anti-static spray intended for vinyl  
LPs.  
REC ERROR: Transferring did not start,  
stopped partway, or otherwise could not  
be performed (page 34).  
REMOVED: The USB device has been  
removed.  
• Do not expose discs to direct sunlight or heat  
sources such as hot air ducts, nor leave it in a  
car parked in direct sunlight.  
STEP FULL: You tried to program more  
than 25 steps.  
TRACK FULL: You cannot transfer onto  
the USB device because the number of  
files have reached its maximum.  
USB READING: The system is reading  
information of the USB device. Some  
buttons are not available.

On safety  
Cleaning the cabinet  
• The unit is not disconnected from the mains as  
long as it is connected to the AC outlet, even  
if the unit itself has been turned off.  
• Completely disconnect the power cord (mains  
lead) from the wall socket (mains) if it is not  
going to be used for an extended period of  
time. When unplugging the unit, always grip  
the plug. Never pull the cord itself.  
Clean this system 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 thinner, benzine, or  
alcohol.  
To prevent a tape from being  
accidentally recorded over  
• Should any solid object or liquid get into the  
system, unplug the system, and have it  
checked by qualified personnel before  
operating it again.  
Break off the tape’s overwrite protection tab  
from side A or B as illustrated.  
• AC power cord must be changed only at the  
qualified service shop.  
Break  
off the  
tape tab  
On placement  
• Do not place the system in an inclined  
position or in locations that are extremely hot,  
cold, dusty, dirty, or humid or lacking  
adequate ventilation, or subject to vibration,  
direct sunlight or a bright light.  
To later reuse the tape for recording, cover the  
broken tab with adhesive tape.  
• Be careful when placing the unit or speakers  
on surfaces that have been specially treated  
(for example, with wax, oil, polish) as staining  
or discoloration of the surface may result.  
• 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 unit, and cause the system to  
malfunction. In this situation, remove the  
disc, and leave the system turned on for about  
an hour until the moisture evaporates.  
About a tape longer than 90 minutes  
The use of the tape with more than 90 minutes  
of play time is not recommended except for  
long, continuous recording or playback.  
Cleaning the tape heads  
Use a dry- or wet-type cleaning tape (available  
separately) after every 10 hours of use, before  
you start an important recording, or after  
playing an old tape. Failure to clean the tape  
heads can cause degraded sound quality or an  
inability of the unit to record or play tapes. For  
details, refer to the instructions of the cleaning  
tape.  
On heat buildup  
• Heat buildup on the unit during operation is  
normal and is not a cause for alarm.  
• Do not touch the cabinet if it has been used  
continuously at a high volume because the  
cabinet may have become hot.  
Demagnetizing the tape heads  
Use a demagnetizing tape (available separately)  
after every 20 to 30 hours of use. Failure to  
demagnetize the tape heads can cause an  
increase in noise, a loss of high frequency  
sound, and an inability to completely erase  
tapes. For details, refer to the instructions of the  
demagnetizing tape.  
• Do not obstruct the ventilation holes.  
On the speaker system  
This speaker system is not magnetically  
shielded, and the picture on nearby TV sets may  
become magnetically distorted. In this situation,  
turn off the TV, wait 15 to 30 minutes, and turn  
it back on. If there is no improvement, move the  
speakers far away from the TV.
