Listening to music through a BLUETOOTH connection
Pairing the system with a BLUETOOTH
device and listening to music
You can enjoy wireless playback of songs stored on a BLUETOOTH device. With devices that
have an NFC function (smartphones, tablets, etc.), BLUETOOTH connection can be established
easily by simply touching your device to the system.
Start with pairing!
When connecting BLUETOOTH devices, the two devices must register each other in advance.
This is called “pairing.” Pairing must be performed when you connect two devices for the first
time. Once a device has been registered through pairing, it does not need to be paired again
when connecting to that same device.
There are two methods of pairing: pairing using the NFC function, and pairing by manually
activating the BLUETOOTH function. Choose the pairing method that matches your device.

edge.
•• Do not clean discs with solvents, such as
benzine, thinner, or commercially available
cleaners or antistatic spray intended for
vinyl LPs.
•• Do not expose discs to direct sunlight
or heat sources such as hot air ducts,
nor leave them in a car parked in direct
sunlight.
34GB
•• 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
system, 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.
•• Do not place the system near lighting
fixtures. The heat from the lighting may
deform the enclosure and cause the
system to malfunction.
•• Be careful when placing the system on
surfaces that have been specially treated
(for example, with wax, oil, polish) as
staining or discoloration of the surface
may result.
•• Do not place heavy objects on the system.
•• 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 system, 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. If the system still
does not operate, even after an extended
period, consult your nearest Sony dealer.
On heat buildup
•• Heat buildup on the unit during charging
or operation over a long period of time is
normal and 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.

BLUETOOTH wireless
technology
BLUETOOTH wireless technology is a shortrange wireless technology that enables
wireless data communication between
digital devices, such as a computer and
digital camera. BLUETOOTH wireless
technology operates within a range of about
10 m.
Connecting two devices as necessary
is common, but some devices can be
connected to multiple devices at the same
time.
You do not need to use a cable for
connection, nor is it necessary for the
devices to face one another, such is the case
with infrared technology. For example, you
can use such a device in a bag or pocket.
BLUETOOTH standard is an international
standard supported by thousands of
companies all over the world, and employed
by various companies worldwide.
Supported BLUETOOTH version and profiles
Profile refers to a standard set of capabilities
for various BLUETOOTH product capabilities.
See “Specifications” (page 37) for details
on the supported BLUETOOTH version and
profiles.
Note
•• To use a BLUETOOTH device connected to this
system, the device must support the same profile
as this system. Note that the functions of the
BLUETOOTH device may be different depending
on the specifications of the device, even if it has
the same profile as this system.
•• Because of the properties of BLUETOOTH wireless
technology, playback on this system is slightly
delayed compared with audio playback on the
transmitting device.
36GB
Effective communication range
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 use
–– Locations where other electromagnetic
waves occur
Interference from other devices
BLUETOOTH devices and wireless LAN
(IEEE802.11b/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 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
Interference to 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 and BLUETOOTH
device in the following locations:
–– In hospitals, on trains, and in airplanes
–– Near automatic doors or fire alarms
Note
•• 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.
