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 after “PROTECT”
disappears.
Are the + and
speaker cords short-
circuited?
Is anything blocking the ventilation holes of
the system?
After 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?
The system has entered standby mode
unexpectedly.
This is not a malfunction. The system enters
standby mode automatically in about
30 minutes when there is no operation or audio
signal output. See “To turn off the automatic
standby function.”
The clock setting or the Play Timer
operation has been cancelled
unexpectedly.
If about a minute elapses with no operation,
the clock setting or Play Timer setting is
cancelled automatically. Perform the operation
again from the beginning.
There is no sound.
Are the + and
speaker cords short-circuited?
Are you using only the supplied speakers?
Is anything blocking the ventilation holes of
the system?
The specified station may have temporarily
stopped broadcast.
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 different wall outlet.

and the remote sensor
on the unit, and
position the unit away from fluorescent lights.
Point the remote at the system’s sensor.
Move the remote closer to the system.
CD/MP3/WMA 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 first track.
Set the play mode to normal play mode.
Starting playback takes more time than
usual.
The following discs can increase the time it
takes to start playback;
a disc recorded with a complicated tree
structure.
a disc recorded in multisession mode.
a disc that has not been finalized (a disc to
which data can be added).
a disc that has many folders.
Tuner
Severe hum or noise, or stations cannot
be received.
Connect the antenna properly.
Try another place and orientation for better
antenna reception.
Keep the antenna away from the speaker cords
and the power cord to avoid picking up noise.
Turn off nearby electrical equipment.
Several radio stations can be heard at the
same time.
Try another place and orientation for better
antenna reception.
Bundle the antenna cable using commercially
available cord clips, for example, and adjust the
cable length.
DAB/DAB+ radio station is not received
properly.
Check all antenna connections, then perform
the DAB Automatic Scan procedure (see
“Reception of DAB/DAB+ radio station”).
The current DAB/DAB+ service may not be
available. Press /PRESET
to select
a different service.
If you have moved to another area, some
services/frequencies may have changed and
you may not be able to tune to your usual
broadcast.
Perform the DAB Automatic Scan procedure to
re-register the contents of broadcasts.
(Performing this procedure clears all previously
stored presets.)

Precautions
Discs that this system CAN play
Audio CD
CD-R/CD-RW (audio data/MP3/WMA files)
Discs that this system CANNOT play
CD-ROM
CD-R/CD-RW other than those recorded in
music CD format, conforming to ISO9660 Level
1/Level 2 or Joliet
CD-R/CD-RW recorded in multisession that
have not ended by “closing the session”
CD-R/CD-RW of poor recording quality, CD-R/
CD-RW that have scratches or are dirty, or
CD-R/CD-RW recorded with an incompatible
recording device
CD-R/CD-RW which is finalized incorrectly
Discs containing files other than MPEG 1 Audio
Layer-3 (MP3)/WMA files
Discs of non-standard shape (for example,
heart, square, star)
Discs that have adhesive tape, paper, or sticker
attached to them
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
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.
Do not expose discs to direct sunlight or heat
sources such as hot air ducts, nor leave them in
a car parked in direct sunlight.
On safety
Completely disconnect the power cord (mains
lead) from the wall outlet (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 qualified personnel before
operating it again.
The AC power cord can be changed only by a
qualified service facility.
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
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.
Cleaning the cabinet
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.
