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 les on the
USB device. If there are many folders or les on the USB device, it
may take a long time to nish reading the USB device.
With some connected USB devices, aer an operation is performed,
there may be a delay before it is performed by this system.
Compatibility with all encoding/writing soware cannot be
guaranteed. If audio les on the USB device were originally encoded
with incompatible soware, those les may produce noise or
interrupted audio, or may not play at all.
is system cannot play audio les on the USB device in the
following cases;
when the number of audio les in a folder exceeds 999.
when the total number of audio les on a USB device exceeds 999.
when the number of folders on a USB device exceeds 999
(including the “ROOT” folder and empty folders).
ese numbers may vary depending on the le and folder structure.
Do not save other types of les or unnecessary folders on a USB
device that has audio les.
e system can play back to a depth of 8 folders only.
is system does not necessarily support all the functions provided
in a connected USB device.
Resume play is cancelled when you turn o the system.
Folders that have no audio les are skipped.
e audio formats that you can listen to with this system are as
follows:
MP3: le extension “.mp3”
WMA: le extension “.wma”
AAC: le extension “.m4a”
Note that even when le name has the correct le extension, if the
actual le diers, 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.
e charging begins when the USB device is connected
to the (USB) port

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 qualied
personnel before operating it again.
e AC power cord can be changed only by a qualied
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
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 pads, scouring powder, or solvents, such as
thinner, benzine, or alcohol.
