Playing back with high
quality sound codec
(AAC/LDAC)
This system can receive data in the
AAC or LDAC codec format from a
BLUETOOTH device. It provides a
playback with higher sound quality.
You can select an audio codec option
from the following two settings by
using “SongPal” (page19). The
default setting of this system is
“AAC ON.”
To apply the changes of the setting,
you need to terminate the BLUETOOTH
connection (page17), and then
perform the BLUETOOTH connection
again.
• AAC ON: The system detects the
codec used on the source device
and automatically selects the
optimal codec from “SBC,” “AAC*” or
“LDAC*.”
• AAC OFF: “SBC” is always applied
regardless of the codec used on the
source device.
* Available only when the codec is
supported by your BLUETOOTH device.
Note
You can enjoy higher sound quality when
the source device is compatible with
AAC/LDAC and this function is set to
“AAC ON.” However, the sound may be
interrupted depending on the conditions
of the BLUETOOTH communication. If this
happens, set the function to “AAC OFF.”
LDAC is an audio coding
technology developed by Sony,
that enables the transmission
of High-Resolution (Hi-Res)
Audio content, even over a
BLUETOOTH connection. Unlike
other BLUETOOTH compatible
coding technologies, such as
SBC, it operates without any
down-conversion of the Hi-Res
Audio content1). It also allows
approximately three times more
data2) than the other technologies,
for transmitting over a
BLUETOOTH wireless network with
unprecedented sound quality using
efficient coding and optimized data
bundling.
1) Excluding DSD format contents.
2) In comparison with SBC (Sub Band
Codec), when the bit rate of 990 kbps
(96/48 kHz) or 909 kbps (88.2/44.1 kHz)
is selected.

Resetting the system
If the system still does not operate
properly, reset the system to factory
default settings.
1
Disconnect and reconnect the
AC power cord, and then turn
on the system.
2
Hold down FUNCTION
PAIRING and the volume
–(minus) button on the unit
for more than 5 seconds.
After the indicator flashes for
more than 3 seconds, all user-
configured settings, such as the
pairing registration information, are
reset to factory default settings.
Precautions
On safety
• Completely disconnect the AC 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.
• AC power cord must be changed only at
the qualified service shop.
On handling the system
This system is not drip-proof or waterproof.
Make sure not to splash water on the
system or clean it with water.
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 system on
surfaces that have been specially treated
(for example, wax, oil, polish) as staining
or discoloration of the surface may result.
On heat buildup
• Heat buildup on the system during
operation is normal and is not a 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
The built-in 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
system 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.

On BLUETOOTH Communication
• BLUETOOTH devices should be used
within approximately 10 meters (33 feet)
(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 are generated
• 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:
— Use this system at least 10 meters
(33 feet) away from the wireless LAN
equipment.
— Turn off the power to the wireless
LAN equipment when using your
BLUETOOTH device within 10 meters
(33 feet).
— Use this system and BLUETOOTH device
as closer to each other as possible.
• 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, in airplanes,
at gas stations, and any place where
flammable gases may be present
— Near automatic doors or fire alarms
• This system supports security
functions that comply with BLUETOOTH
specifications to ensure secure
connections 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.
