Notes
 When USB cable connection is necessary, connect the USB cable
supplied with the USB device to be connected. See the operation
manual supplied with the USB device to be connected for details on
the operation method.
 It may take about 10 seconds before “Reading” appears depending
on the type of USB device connected.
 Do not connect the system and the USB device through a USB hub.
 When the USB device is inserted, the system reads all the files on the
USB device. If there are many folders or files on the USB device, it
may take a long time to finish reading the USB device.
 With some connected USB devices, after an operation is performed,
there may be a delay before it is performed by this system.
 Compatibility with all encoding/writing software cannot be
guaranteed. If audio files on the USB device were originally encoded
with incompatible software, those files may produce noise or
interrupted audio, or may not play at all.
 This system cannot play audio files on the USB device in the
following cases;
 when the number of audio files in a folder exceeds 999.
 when the total number of audio files on a USB device exceeds 999.
 when the number of folders on a USB device exceeds 999
(including the “ROOT” folder and empty folders).
These numbers may vary depending on the file and folder structure.
Do not save other types of files or unnecessary folders on a USB
device that has audio files.
 The system can play back to a depth of 8 folders only.
 This system does not necessarily support all the functions provided
in a connected USB device.
 Resume play is cancelled when you turn off the system.
 Folders that have no audio files are skipped.
 The audio formats that you can listen to with this system are as
follows:
 MP3: file extension “.mp3”
 WMA: file extension “.wma”
 AAC: file extension “.m4a”
Note that even when file name has the correct file extension, if the
actual file differs, the system may produce noise or may malfunction.
To use the system as a battery charger
You can use the system as a battery charger for USB
devices that have a rechargeable function when the
system is on.
The charging begins when the USB device is connected
to the (USB) port . The charge status appears in
the USB device display. For details, see the user’s guide of
your USB device.

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.
