Precautions
Discs that this system CAN play
Audio CD
CD-R/CD-RW (audio data/MP3 files)
Discs that this system CANNOT play
CD-ROM
CD-R/CD-RW other than those recorded in music CD
format or MP3 format conforming to ISO9660 Level
1/Level 2, 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) 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 it 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.
AC power cord must be changed only at a qualified
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
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.

Troubleshooting
1
Make sure the power cord and speaker cords are
correctly and firmly 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 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?
Are you using only the supplied speakers?
Is anything blocking the ventilation holes on the top
or back of the system?
Is the iPod connector short-circuited?
After the STANDBY indicator
stops flashing,
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?
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?
The specified station may have temporarily stopped
broadcast.
The STANDBY indicator
remains lit after
unplugging the power cord.
The STANDBY indicator
may not turn off
immediately after unplugging the power cord. This
is not a malfunction. The indicator will turn off after
about 40 seconds.
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.
Install a noise filter (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 fluorescent 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 first track.
Return to Normal Play by pressing PLAY MODE
repeatedly until both “PGM” and “SHUF” disappear.
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.
The system does not eject the disc 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 “STEREO” flashes 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 off nearby electrical equipment.
“TUNED” does not appear in the display (DAB
only).
Check all antenna connections, then perform the DAB
Automatic Scan procedure (see “Reception of DAB
radio station (CMT-LX40i only)”).
The current DAB service may not be available. Press
+/
