connected.
2 Find your problem in the checklist
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?
After the STANDBY indicator 
stops flashing, reconnect the power
cord, and turn on the system. If the
issue persists, contact your nearest
Sony dealer.
There is no sound.
If the BLUETOOTH indicator  is lit
or flashing when a function other than
the Bluetooth function is selected, no
sound is heard through the speakers
or PHONES jack . Press and hold

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 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 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.
30GB
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.

Bluetooth wireless
technology
Bluetooth wireless technology is a shortrange wireless technology linking digital
devices, such as personal computers and
digital still cameras. Using the Bluetooth
wireless technology, you can operate the
units involved within a range of about 10
meters.
The Bluetooth wireless technology is
commonly used between two devices,
but a single device can be connected to
multiple devices.
You do not need wires to get connected
as you do with a USB connection, and
you do not need to place the devices face
to face as you do with wireless infrared
technology. You can use the technology
with one Bluetooth device in your bag
or pocket.
Bluetooth wireless technology is a global
standard supported by thousands of
companies. These companies produce
products that meet the global standard.
Supported Bluetooth version and
profiles
Profile refers to a standard set of
capabilities for various Bluetooth product
capabilities. This system supports the
following Bluetooth version and profiles.
Supported Bluetooth version:
Bluetooth Standard version 2.0
Supported Bluetooth profiles:
A2DP (Advanced Audio Distribution
Profile)
AVRCP (Audio Video Remote
Control Profile)
Effective communication range
Effects of other devices
Bluetooth devices and wireless LAN
(IEEE 802.11b/g) use the same frequency
band (2.4 GHz). When using your
Bluetooth device near a device with
wireless LAN capability, electromagnetic
interference may occur. This could result
in lower data transfer rates, noise, or
inability to connect. If this happens, try
the following remedies:
Try connecting this system and
Bluetooth mobile phone or Bluetooth
device when you are at least 10
meters away from the wireless LAN
equipment.
Turn off the power to the wireless LAN
equipment when using your Bluetooth
device within 10 meters.
Effects on other devices
The radio waves broadcast by this system
may interfere with the operation of some
medical devices. Since this interference
may result in malfunction, always turn
off the power on this system, Bluetooth
mobile phone and Bluetooth device in
the following locations:
In hospitals, on trains, in airplanes,
at gas stations, and any place where
flammable gasses may be present
Near automatic doors or fire alarms
Notes
This system supports security functions that
comply with the Bluetooth specification
as a means of ensuring security during
communication using Bluetooth technology.
However, this security may be insufficient
depending on the setting contents and
other factors, so always be careful when
performing communication using Bluetooth
technology.
Sony cannot be held liable in any way
for damages or other loss resulting from
information leaks during communication
using Bluetooth technology.
Bluetooth communication is not necessarily
guaranteed with all Bluetooth devices that
have the same profile as this system.
Bluetooth devices connected with this system
must comply with the Bluetooth specification
prescribed by the Bluetooth SIG, Inc., and
must be certified to comply. However, even
when a device complies with the Bluetooth
specification, there may be cases where
the characteristics or specifications of the
Bluetooth device make it impossible to
connect, or may result in different control
methods, display or operation.
Noise may occur or the audio may
cut off depending on the Bluetooth
device connected with this system,
the communications environment, or
surrounding conditions.
Others
Bluetooth devices should be used within
approximately 10 meters (unobstructed
distance) of each other. The effective
communication range may become
shorter under the following conditions.
When a person, metal object, wall
or other obstruction is between the
devices with a Bluetooth connection
Locations where a wireless LAN is
installed
Around microwave ovens that are in
