What is Bluetooth wireless technology?
Bluetooth®wireless technology is a
short-range wireless technology that
enables wireless data communication
between digital devices, such as a
computer or digital camera. Bluetooth
wireless technology operates within a
range of about 10 meters (about 30
feet).
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.
Communication System and
Compatible Bluetooth Profiles
of this unit
Profile is standardization of the
function for each Bluetooth device
specification. This unit supports the
following Bluetooth version and
profiles:
Communication System:
Bluetooth Specification version 3.0
Compatible Bluetooth Profiles:
– A2DP (Advanced Audio Distribution
Profile): Transmitting or receiving audio
content of high-quality.
– AVRCP (Audio Video Remote Control
Profile): Controlling A/V equipment;
pausing, stopping, or starting playback,
etc.
– HSP (Headset Profile)*: Talking on the
phone/Operating the phone.
– HFP (Hands-free Profile)*: Talking on the
phone/Operating the phone by
hands-free.
* When you use a Bluetooth mobile phone
supported by both HFP (Hands-free
Profile) and HSP (Headset Profile), set to
HFP.
Notes
To be able to use the Bluetooth function,
the Bluetooth device to be connected
requires the same profile as the unit’s.
Note also that even if the same profile
exists, devices may vary in function
depending on their specifications.
Due to the characteristic of Bluetooth
wireless technology, the sound played on
this unit is slightly delayed from the sound
played on the Bluetooth device during
talking on the telephone or listening to the
music.

Caution
If this unit detects a problem while
charging, the indicator (red) may turn
off, although charging is not complete.
Check for the following causes:
– Ambient temperature is too low
(approx. 10 °C (50 °F) or lower).
– Ambient temperature is too high
(approx. 35 °C (95 °F) or higher).
– There is a problem with the battery.
Firstly, try charging the battery in a
suitable temperature range. If the
problem persists, consult your nearest
Sony dealer.
Notes
If the battery is not used for a long time,
battery may be quickly depleted, however,
after a few recharges, battery life will
improve.
When you do not use the unit for a long
time, charge the rechargeable battery at
least biannually to avoid the deterioration
of the battery.
If the battery is not used for a long time,
charging may take more time.
If the life of the built-in rechargeable
battery drops to half the normal length,
the battery should be replaced. Consult
your nearest Sony dealer for replacement
of the rechargeable battery.
Avoid exposure to temperature extremes,
direct sunlight, moisture, sand, dust or
mechanical shock. Never leave in a car
parked in the sun.
If the computer enters hibernation mode
while connected to the carrying case,
charging will not be completed properly.
Check the setting of the computer before
charging. The indicator will go off
automatically even if the computer enters
hibernation mode. Charge the unit again
in this case.
Use the supplied USB cable only, and
connect the carrying case directly to a
computer. Charging will not be completed
properly by an indirect connection, such
as via a USB hub. Continued

Pairing
What is pairing?
Bluetooth devices need to be “paired”
with each other beforehand.
Once Bluetooth devices are paired,
there is no need for pairing again,
except in the following cases:
Pairing information is deleted after
repair, etc.
When you attempt to pair with 9 or
more devices.
This unit can be paired with up to 8
devices; if a new device is paired
after 8 devices have been paired, the
device whose latest connection time
is the oldest among the 8 paired
devices is replaced by the new one.
When recognition of the unit by the
device to be connected is deleted.
This unit is initialized (page 31). All
pairing information is deleted.
Pairing procedures
Before pairing, charge the headset
(page 11, 13).
1Place the Bluetooth device
within 1 m (3 ft) of this unit.
2While this unit is turned off,
press and hold the (Multi
function) button until the
indicator flashes blue and red
alternately.
The unit enters pairing mode. (It
takes about 7 seconds normally to
enter pairing mode. When pairing
for the first time, or the unit is
initialized, etc., pairing takes about
2 seconds.)
Note
If pairing is not established within about
5 minutes, pairing mode will be canceled
and this unit will turn off. In this case,
start over from step 1.

3Perform the pairing procedure
on the Bluetooth device to
detect this unit.
The list of detected devices appears
on the display of the Bluetooth
device. This unit is displayed as
“XBA-BT75.” If “XBA-BT75” is not
displayed, repeat from step 1.
Notes
For details, refer to the operating
instructions supplied with the
Bluetooth device.
When pairing with a Bluetooth device
that cannot display a list of detected
devices or that has no display, you
may pair the device by setting both
this unit and the Bluetooth device to
pairing mode. At this time, if passkey*
is set besides “0000” on the Bluetooth
device, pairing cannot be done with
this unit.
* Passkey may be called “Passcode,”
“PIN code,” “PIN number,” or
“Password.”
4Select “XBA-BT75” on the
display of the Bluetooth device.
5If passkey input is required on
the display of a Bluetooth
device, input “0000.”
Pairing is complete when the
indicator (blue) flashes slowly (or
flashes twice). A message that
pairing is complete appears on the
display of some Bluetooth devices.
Note
Passkey input may not be required
depending on the connected Bluetooth
device. For details, refer to the operating
instructions supplied with the Bluetooth
device.
6Start the Bluetooth connection
from the Bluetooth device.
This unit memorizes the device as
the last connected device. Some
Bluetooth devices may connect
with the unit automatically when
pairing is complete.
Tips
To pair with other Bluetooth devices,
repeat steps 1 to 5 for each device.
To delete all pairing information, see
“Initializing the unit” (page 31).

How to install the
earbuds correctly
If the earbuds do not fit your ears
correctly, low-bass sound may not be
heard. To enjoy better sound quality,
position the headset comfortably on
your ears, with the earbuds fitted
snugly on your ears.
If the earbuds are not a snug fit, try
another size. Confirm the size of the
earbuds by checking the color inside.
Note
The supplied earbuds are for this unit only.
Do not use with another device.
To detach an earbud
While holding the headset, carefully
peel back the earbud and twist off by
the inner sleeve.
Tip
If the earbud slips and cannot be detached,
wrap it in a dry soft cloth.
To attach an earbud
When you change the earbuds, install
them firmly on the headset to prevent
the earbud from detaching and
remaining in your ear.
