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:
ˋReorient or relocate the receiving antenna.
ˋIncrease the separation between the 
equipment and receiver.
ˋConnect the equipment into an outlet on a 
circuit different from that to which the receiver 
is connected.
ˋConsult 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 
and Industry Canada's licence-exempt RSSs. 
Operation is subject to the following two 
conditions: 
(1) This device may not cause interference; and 
(2) This device must accept any interference, 
including interference that may cause undesired 
operation of the device.
This transmitter must not be co-located or operated 
in conjunction with any other antenna or 
transmitter.
Under Industry Canada regulations, this radio 
transmitter may only operate using an antenna of a 
type and maximum (or lesser) gain approved for 
the transmitter by Industry Canada. To reduce 
potential radio interference to other users, the 
antenna type and its gain should be so chosen that 
the equivalent isotropically radiated power (e.i.r.p.) 
is not more than that necessary for successful 
communication.
This equipment complies with FCC/IC radiation 
exposure limits set forth for an uncontrolled 
environment and meets the FCC radio frequency 
(RF) Exposure Guidelines and RSS-102 of the IC 
radio frequency (RF) Exposure rules. This 
equipment has very low levels of RF energy that is 
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.
Note on the lithium battery
Do not expose the battery to excessive heat such as 
direct sunlight, fire or the like.
Disclaimer regarding services offered by 
third parties
Services offered by third parties may be changed, 
suspended, or terminated without prior notice. 
Sony does not bear any responsibility in these sorts 
of situations.
Warning if your car’s ignition has no ACC 
position
Be sure to set the AUTO OFF function (page 19). 
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.

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).
On BLUETOOTH communication

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.
ˋwhere inflammable gas is present, in a hospital, 
train, airplane, or petrol station
ˋnear automatic doors or a fire alarm
ˎThis 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.
ˎWe do not take any responsibility for the leakage 
of information during BLUETOOTH 
communication.
If you have any questions or problems concerning 
your unit that are not covered in this manual,

Preparing a BLUETOOTH Device
You can enjoy music, or perform handsfree calling 
depending on the BLUETOOTH compatible device 
such as a smartphone, cellular phone and audio 
device (hereafter “BLUETOOTH device” if not 
otherwise specified). For details on connecting, 
refer to the operating instructions supplied with the 
device.
Before connecting the device, turn down the 
volume of this unit; otherwise, loud sound may 
result.
By touching the control dial on the unit with an 
NFC* compatible smartphone, the unit is paired and 
connected with the smartphone automatically.
* NFC (Near Field Communication) is a technology 
enabling short-range wireless communication 
between various devices, such as mobile phones and 
IC tags. Thanks to the NFC function, data 
communication can be achieved easily just by 
touching the relevant symbol or designated location 
on NFC compatible devices.
For a smartphone with Android OS 4.0 or lower 
installed, downloading the app “NFC Easy Connect” 
available at Google Play™ is required. The app may 
not be downloadable in some countries/regions.
1Activate the NFC function on the 
smartphone.
For details, refer to the operating instructions 
supplied with the smartphone.
2Touch the N-Mark part of the unit with 
the N-Mark part of the smartphone.
Make sure that   lights up on the display of the 
unit.
To disconnect by One touch
Touch the N-Mark part of the unit with the N-Mark 
part of the smartphone again.
Notes
ˎWhen making the connection, handle the 
smartphone carefully to prevent scratches.
ˎOne touch connection is not possible when the unit is 
already connected to another NFC compatible device. 
In this case, disconnect the other device, and make 
connection with the smartphone again.
When connecting a BLUETOOTH device for the first 
time, mutual registration (called “pairing”) is 
required. Pairing enables this unit and other devices 
to recognize each other.

Cautions
ˎRun all ground (earth) leads to a common 
ground (earth) point.
ˎDo not get the leads trapped under a screw, or 
caught in moving parts (e.g., seat railing).
ˎBefore making connections, turn the car ignition 
off to avoid short circuits.
ˎConnect the yellow and red power supply leads 
only after all other leads have been connected.
ˎBe sure to insulate any loose unconnected leads 
with electrical tape for safety.
ˎChoose the installation location carefully so that 
the unit will not interfere with normal driving 
operations.
ˎAvoid installing the unit in areas subject to dust, 
dirt, excessive vibration, or high temperature, 
such as in direct sunlight or near heater ducts.
ˎUse only the supplied mounting hardware for a 
safe and secure installation.
Note on the power supply lead (yellow)
When connecting this unit in combination with other 
stereo components, the amperage rating of the car 
circuit to which the unit is connected must be higher 
than the sum of each component’s fuse amperage 
rating.
Mounting angle adjustment
Adjust the mounting angle to less than 45°.
Parts List for Installation
ˎThis parts list does not include all the package 
contents.
ˎThe bracket ʓ and the protection collar ʕ are 
attached to the unit before shipping. Before
