General
The demonstration appears in the display after
plugging in the power cord even though the
system is not turned on.
Press DISPLAY  once while the system is off. The
demonstration disappears.
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.
Install a noise filter (not supplied) 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.
The STANDBY indicator  remains lit after
unplugging the power cord.
The STANDBY indicator  may not turn off
immediately after unplugging the power cord. The
indicator will turn off after about 40 seconds. This is not
a malfunction.

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

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.
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 pads, scouring powder, or solvents, such as
thinner, benzine, or alcohol.
