Troubleshooting
1 Make sure the power cord and speaker cords are
correctly and rmly connected.
2 Find your problem in the checklist below, and take
the indicated corrective action.
If the issue persists, contact your nearest Sony dealer.
If “PROTECT” appears on the display
Immediately unplug the power cord, and check the
following items aer “PROTECT” disappears.
If your system has a voltage selector, is the voltage
selector set to the correct voltage?
Are the + and – speaker cords short-circuited?
Is anything blocking the ventilation holes on the top
or back of the system?
Aer you have checked these above items and found
to be all right, reconnect the power cord, and turn on
the system. If the issue persists, contact your nearest
Sony dealer.
General
The system does not turn on.
Is the power cord plugged in?
Is the voltage selector set correctly to match the local
power line voltage?
There is no sound.
Are the + and – speaker cords short-circuited?
Are you using only the supplied speakers?
Is anything blocking the ventilation holes on the top or
back of the system?
Sound comes from one channel, or the left and
right volumes are unbalanced.
Place the speakers as symmetrically as possible.
Connect only the supplied speakers.
Severe hum or noise.
Move the system away from sources of noise.
Connect the system to a dierent wall socket.
Install a noise lter (available separately) to the power
cord.
The remote does not function.
Remove any obstacles between the remote and the
remote sensor
on the unit, and position the unit
away from uorescent lights.
Point the remote at the system’s sensor.
Move the remote closer to the system.
CD/MP3 player
The sound skips, or the disc will not play.
Wipe the disc clean, and replace it.
Move the system to a location away from vibration (for
example, on top of a stable stand).
Move the speakers away from the system, or place them
on separate stands. At high volume, speaker vibration
may cause the sound to skip.
Play does not start from the rst track.
Return to Normal Play by pressing PLAY MODE
repeatedly until both “PGM” and “SHUF” disappear.
Starting playback takes more time than usual.
e following discs take a longer time to start playback.
a disc recorded with a complicated tree structure.
a disc recorded in multisession mode.
a disc that has not been nalized (a disc to which data
can be added).
a disc that has many folders.
The disc tray does not open and “LOCKED”
appears.
Contact your Sony dealer or local authorized Sony
service facility.
Tuner
Severe hum or noise, or stations cannot be
received. (“TUNED” or “ST” ashes on the
display.)
Connect the antenna properly.
Find a location and an orientation that provide good
reception, and then set up the antenna again.
Keep the antennas away from the speaker cords and the
power cord to avoid picking up noise.
Turn o nearby electrical equipment.
Tape deck (Except for the UK model)
The sound exhibits excessive wow or utter or
dropout.
Clean the capstans and pinch rollers. Also, clean and
demagnetize the tape heads. See “Precautions” for details.
To change the AM tuning interval
e AM tuning interval is factory-preset to 9 kHz or
10 kHz (for some areas: this function is not available on
the European and Russian models).
Use buttons on the unit to change the AM tuning
interval.
1 Tune in any AM station, and then turn o the
system.
2 Press DISPLAY
to display the clock.
3 While holding down TUNING +
, press 
.
All the AM preset stations are erased. To reset the
interval to the factory preset, repeat the procedure.
On safety
e 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 o.
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.
Should any solid object or liquid get into the system,
unplug the system, and have it checked by qualied
personnel before operating it again.
AC power cord must be changed only at a qualied
service shop.
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.
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 CD player, 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.
On heat buildup
Heat buildup on the unit during operation is normal
and is not 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.
Do not obstruct the ventilation holes.
On the speaker system
is speaker system is not magnetically shielded, and
the picture on nearby TV sets may become magnetically
distorted. In this situation, turn o 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.
Cleaning the cabinet
Clean this system with a so 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 (Except for the UK model)
Break o the cassette’s overwrite protection tab from side
A or B as illustrated.
Break o the cassette
tab
To later reuse the tape for recording, cover the broken tab
with adhesive tape.
About a tape longer than 90 minutes (Except
for the UK model)
e 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 (Except for the UK
model)
Use dry- or wet-type cleaning cassette (available
separately) aer every 10 hours of use, before you start an
important recording, or aer 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 cassette.
Demagnetizing the tape heads (Except for the
UK model)
Use a demagnetizing cassette (available separately) aer
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 cassette.
