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 aer “PROTECT” disappears.
Are the + and speaker cords short-circuited?
Is anything blocking the ventilation holes on the top
or back of the system?
Aer 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?
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.

Precautions
Discs that this system CAN play
Audio CD
CD-R/CD-RW (audio data/MP3 les)
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 nalized incorrectly
Discs containing les other than MPEG 1 Audio
Layer-3 (MP3) les
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
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 qualied
personnel before operating it again.
AC power cord must be changed only at a qualied
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.
