Notes on Using Bluetooth
®
/Wireless
LAN (Wi-Fi
®
) Functions
Precautions for Bluetooth
®
•
The Bluetooth
®
function of the product conforms to the domestic
standards of Japan, FCC standards and EC directives, and has been
certified.
•
The 2.4 GHz band used by wireless LAN (Wi-Fi
®
) and Bluetooth
®
devices is shared by various other devices. For this reason,
Bluetooth
®
devices use technologies for minimizing effects from other
devices using the same radio frequency band. In some cases,
however, the communication speed and connectable range may be
decreased, or disconnection may occur, due to interference by other
devices.
•
The communication speed and connectable range vary depending
on the distance between communication devices, obstacles and the
connected devices used.
Precautions for Wireless LAN (Wi-Fi
®
)
•
The wireless LAN (Wi-Fi
®
) function of the product conforms to the
domestic standards of Japan, FCC standards and EC directives, and
has been certified.
•
Do not use the product in places where electromagnetic waves are
generated or near electric products, AV and OA equipment, or other
magnetized devices.
•
Subjecting the product to magnetic or electrical noise might increase
noise or prevent it from performing communications. (The product is
particularly susceptible to noise when it is used near a microwave
oven.)
•
Using the product near a TV, radio or similar appliance might cause
reception interference or disrupt TV images.
•
Search for access points might not be successful if there are multiple
wireless LAN (Wi-Fi
®
) access points near the product and the same
channel is being used.
•
The communication speed and connectable range vary depending
on the distance between communication devices, obstacles and the
connected devices used.
Frequency Band
Bluetooth
®
and wireless LAN (Wi-Fi
®
) functions (2.4 GHz band) of the
product use frequencies in the 2.4 GHz band ranging from 2.402 GHz
to 2.480 GHz.
To view information on frequency band, perform the following
operations.

Bluetooth
®
function: 2.4FH1/XX4
The product uses the 2.4 GHz band.
FH1 uses FH-SS as the modulation scheme. The interference
distance is about 10 m or less.
XX4 uses other schemes. The interference distance is about 40 m or
less.
Bands of mobile unit identification devices cannot be avoided.
•
Wireless LAN (Wi-Fi
®
) function: 2.4DS/OF4
The product uses the 2.4 GHz band.
DS-SS and OFDM are used as the modulation schemes. The
interference distance is about 40 m or less.
Bands of mobile unit identification devices can be avoided.
Channels available with the 2.4 GHz band wireless LAN (Wi-Fi
®
) of
the product are between 1 and 13.
Available channels differ depending on the country.
For use on airplanes, check with the respective airlines in advance.
■
Precautions for Use of Bluetooth
®
Function
The frequencies used by the Bluetooth
®
function of the product are in
the 2.4 GHz band. In this frequency band, in addition to home
electrical appliances such as microwave ovens and industrial, scientific
and medical devices, other similar wireless stations, in-plant wireless
stations for mobile unit identification that require a license for use such
as factory production lines, specific small power wireless stations that
do not require licenses, and amateur wireless stations (collectively
called "other wireless stations" from here on) are operated.
1. Before using the product, make sure that "other wireless stations"
are not in operation nearby.
2. In the event that instances of radio wave interference have occurred
between the product and "other wireless stations," immediately
either relocate the product or stop operation of the device (stop the
emission of radio waves).
3. If you are unclear on any points or are troubled by anything, contact
an au shop or Customer Service Center.

◎
Connections between the product and all other Bluetooth
®
and
wireless LAN (Wi-Fi
®
) devices have not been confirmed. Therefore,
connections with all Bluetooth
®
and wireless LAN (Wi-Fi
®
) devices
are not guaranteed.
◎
The product supports security features for wireless
communications that are compliant with the Bluetooth
®
and
wireless LAN (Wi-Fi
®
) standard specifications, but the security may
not be sufficient depending on the usage environment and
configuration.
Be careful when establishing data communication using
Bluetooth
®
or wireless LAN (Wi-Fi
®
) function.
◎
Wireless LAN (Wi-Fi
®
) has the advantage that it can be freely
connected anywhere within the radio wave range, as it uses radio
waves for exchanging information. At the same time, there is a risk
that a malicious third party may obtain unauthorized access if
security settings have not been configured. You are recommended
to configure security settings before using wireless LAN (Wi-Fi
®
) at
your own discretion and risk.
◎
The Company assumes no responsibility for leakage of data or
information that may occur during Bluetooth
®
/wireless LAN (Wi-Fi
®
)
communication.
◎
Since Bluetooth
®
and wireless LAN (Wi-Fi
®
) functions use the
same frequency band, using the both functions at the same time
may cause radio wave interference resulting in decreased
communication speed or disconnection from the network. If
connection fails, stop using either of the Bluetooth
®
and wireless
LAN (Wi-Fi
®
) functions.
Notes on Voluntary Control of Radio
Interference
The product conforms to technical regulations pursuant to the Rules
for Voluntary Control Measures of VCCI; the corresponding conformity
mark is shown on the electronic rating plate on the product.
To view the electronic rating plate, perform the following operations.

Notes on Packet Communication Fee
•
Since a constant Internet connection is possible with the product,
packet communication may be performed automatically by some
applications, resulting in high packet communication fees. Therefore,
subscription to the flat-rate/discount service for packet
communication fees is recommended.
•
To browse websites, download applications, communicate using
applications, send/receive e-mails or configure various settings,
connection to the Internet is required, to which packet
communication fee applies.
(Packet communication fee does not apply to wireless LAN (Wi-Fi
®
).)
Notes on Applications
•
Be sure to check the security of the application, then install it at your
own risk. Some applications might cause virus infection, damage
various data, and send out your location information, usage history or
personal information stored in your cell phone via the Internet.
•
The Company assumes no responsibility for any problems caused by
applications you have installed. In such cases, you may be charged a
repair fee even during the warranty period.
•
The Company assumes no responsibility for any loss or damage
suffered by you or any third party as a result of using applications you
have installed.
•
Some applications may not be used unless a microSD memory card
is inserted into the product.
•
Some applications keep the display turned on while they are active,
or rapidly drain the battery while running in the background.
•
Operation procedures and screen appearances of the applications
preinstalled in the product and those installed by you are subject to
change without notice as a result of version upgrade. In addition,
operation procedures described in the Basic Manual (this manual)
available on the au website and on the product may differ from the
actual procedures.
