Pairing this system with a Bluetooth
device
Pairing is an operation where Bluetooth
devices register with each other
beforehand. Use the procedure below
to pair the system with your Bluetooth
device. Once a pairing operation is
performed, it does not need to be
performed again. If pairing is already
completed, proceed to “Playing music of
a Bluetooth device” (page 17).
Place the Bluetooth device to be
connected to this system within
1 meter of the system.
Select the Bluetooth function.
Press BLUETOOTH   on
the unit.
Operate the Bluetooth device
and perform the pairing
operation.
For details about the operations of
the Bluetooth device, refer to the
operation manual supplied with your
Bluetooth device.
When searching for this system with
the Bluetooth device, a list of the
devices found may appear in the
Bluetooth device display depending
on the type of Bluetooth device.
This system appears as “CMTBX50BTi” depending on the model.
When establishing a connection with
this system, select the audio profile
(A2DP, AVRCP) at the Bluetooth
device. If the Bluetooth device does
not support the AVRCP profile, you
cannot perform playback or other
operations with the system (page 17).
Enter the passkey.
Passkey entry may be required
depending on the type of Bluetooth
device.
When “PIN?” and a countdown

on the remote (or
+/ and
/  on the unit) 
to enter the same passkey that was
entered at the Bluetooth device, and
then press .
Once pairing is completed and the
connection is established, the system
display changes as follows:
“Connect”  Name of the Bluetooth
device
To cancel passkey entry partway
Press  .
If passkey entry still required, turn off the
Bluetooth device.
Notes
 “Passkey” may be called “Passcode,” “PIN
code,” “PIN number” or “Password,” etc.
depending on the device.
 This system only supports numerical
passkeys up to 4 digits.
 The pairing standby status of the system is
cancelled after about 30 seconds.
If pairing is not successful, redo the
procedure from step 1.
 While connected to a Bluetooth device, this
system cannot be detected and a connection
cannot be established from another
Bluetooth device.

Troubleshooting
1 Make sure the power cord and
speaker cords are correctly and firmly
connected.
2 Find your problem in the checklist
below, and take the indicated
corrective action.
If the issue persists, contact your
nearest Sony dealer.
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?
 Is the iPod connector  shortcircuited?
After the STANDBY indicator 
stops flashing, reconnect the power
cord, and turn on the system. If the
issue persists, contact your nearest
Sony dealer.

 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 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.
 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.

 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.

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
Effect
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

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.

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
gnetic
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
