Note on the lithium battery
Do not expose the battery to excessive heat
such as direct sunlight, fire or the like.
Warning
This equipment has been tested and found to
comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference in a
residential installation. This equipment
generates, uses, and can radiate radio
frequency energy and, if not installed and used
in accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that
interference will not occur in a particular
installation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by turning
the equipment off and on, the user is
encouraged to try to correct the interference by
one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the
equipment and receiver.
Connect the equipment into an outlet on a
circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/
TV technician for help.
You are cautioned that any changes or
modifications not expressly approved in this
manual could void your authority to operate this
equipment.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) this device may not cause
harmful interference, and (2) this device must
accept any interference received, including
interference that may cause undesired
operation.
This transmitter must not be co-located or
operated in conjunction with any other antenna
or transmitter.
This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency
(RF) Exposure Guidelines. This equipment has
very low levels of RF energy that it deemed to
comply without maximum permissive exposure
evaluation (MPE). But it is desirable that it
should be installed and operated keeping the
radiator at least 20 cm or more away from
person’s body (excluding extremities: hands,
wrists, feet and ankles).
For the State of California, USA only
Perchlorate Material – special handling may
apply, See
www.dtsc.ca.gov/hazardouswaste/perchlorate
Perchlorate Material: Lithium battery contains
perchlorate
Be sure to install this unit in the dashboard of
the car for safety.
For installation and connections, see the
supplied installation/connections manual.
Warning if your car’s ignition has no ACC

(page 17). The unit will shut off completely
and automatically in the set time after the
unit is turned off, which prevents battery
drain. If you do not set the AUTO OFF
function, press and hold OFF until the display
disappears each time you turn the ignition
off.

answering a call if driving conditions so
require.
Connecting to other devices
When connecting to any other device, please
read its user guide for detailed safety
instructions.
Radio frequency exposure
RF signals may affect improperly installed or
inadequately shielded electronic systems in
cars, such as electronic fuel injection
systems, electronic antiskid (antilock)
braking systems, electronic speed control
systems or air bag systems. For installation
or service of this device, please consult with
the manufacturer or its representative of
your car. Faulty installation or service may be
dangerous and may invalidate any warranty
that may apply to this device.

Emergency calls
This BLUETOOTH car handsfree and the
electronic device connected to the handsfree
operate using radio signals, cellular, and
landline networks as well as user-
programmed function, which cannot
guarantee connection under all conditions.
Therefore do not rely solely upon any
electronic device for essential
communications (such as medical
emergencies).
Remember, in order to make or receive calls,
the handsfree and the electronic device
connected to the handsfree must be
switched on in a service area with adequate
cellular signal strength.
Emergency calls may not be possible on all
cellular phone networks or when certain
network services and/or phone features are
in use.
Check with your local service provider.

What is BLUETOOTH technology?
BLUETOOTH wireless technology is a short-
range wireless technology that enables
wireless data communication between
digital devices, such as a cellular phone
and a headset. BLUETOOTH wireless
technology operates within a range of
about 10 m (33 ft). Connecting two devices
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 since BLUETOOTH technology is
a wireless technology, neither 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 technology is an international
standard supported by millions of
companies all over the world, and
employed by various companies
worldwide.
On BLUETOOTH communication
BLUETOOTH wireless technology operates
within a range of about 10 m (33 ft).
Maximum communication range may vary
depending on obstacles (person, metal,
wall, etc.) or electromagnetic environment.
The following conditions may affect the
sensitivity of BLUETOOTH communication.
There is an obstacle such as a person,
metal, or wall between this unit and
BLUETOOTH device.
A device using 2.4 GHz frequency, such
as a wireless LAN device, cordless
telephone, or microwave oven, is in use
near this unit.
Because BLUETOOTH devices and wireless
LAN (IEEE802.11b/g) use the same
frequency, microwave interference may
occur and result in communication speed
deterioration, noise, or invalid connection if
this unit is used near a wireless LAN device.
In such as case, perform the following.
Use this unit at least 10 m (33 ft) away
from the wireless LAN device.
If this unit is used within 10 m (33 ft) of a
wireless LAN device, turn off the wireless
LAN device.
Install this unit and BLUETOOTH device
as near to each other as possible.
Microwaves emitting from a BLUETOOTH
device may affect the operation of
electronic medical devices. Turn off this
unit and other BLUETOOTH devices in the
following locations, as it may cause an
accident.
where inflammable gas is present, in a
hospital, train, airplane, or petrol station
near automatic doors or a fire alarm
This unit supports security capabilities that
comply with the BLUETOOTH standard to
provide a secure connection when the
BLUETOOTH wireless technology is used,
but security may not be enough
depending on the setting. Be careful when
communicating using BLUETOOTH wireless
technology.
We do not take any responsibility for the
leakage of information during BLUETOOTH
communication.
Connection with all BLUETOOTH devices
cannot be guaranteed.
A device featuring BLUETOOTH function
is required to conform to the
BLUETOOTH standard specified by
BLUETOOTH SIG, and be authenticated.
Even if the connected device conforms
to the above mentioned BLUETOOTH
standard, some devices may not be

connected or work correctly, depending
on the features or specifications of the
device.
While talking on the phone hands free,
noise may occur, depending on the
device or communication environment.
Depending on the device to be connected,
it may require some time to start
communication.
Others
Using the BLUETOOTH device may not
function on cellular phones, depending on
radio wave conditions and location where
the equipment is being used.
If you experience discomfort after using
the BLUETOOTH device, stop using the
BLUETOOTH device immediately. Should
any problem persist, consult your nearest
Sony dealer.
If you have any questions or problems
concerning your unit that are not covered in
this manual, consult your nearest Sony
dealer.
Maintenance
Replacing the lithium battery of the
remote commander
When the battery becomes weak, the range
of the remote commander becomes shorter.
Replace the battery with a new CR2025
lithium battery. Use of any other battery may
present a risk of fire or explosion.
Notes on the lithium battery
Keep the lithium battery out of the reach of
children. Should the battery be swallowed,
immediately consult a doctor.
Wipe the battery with a dry cloth to assure a good
contact.
Be sure to observe the correct polarity when
installing the battery.
Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
Cleaning the connectors
The unit may not function properly if the
connectors between the unit and the front
panel are not clean. In order to prevent this,
detach the front panel (page 7) and clean the
connectors with a cotton swab. Do not apply
too much force. Otherwise, the connectors
may be damaged.
WARNING
Battery may explode if mistreated.
Do not recharge, disassemble, or dispose
of in fire.
