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 metres.
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:

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.

Maximum communication range may
vary depending on obstacles (human body,
metal, wall, etc.) or electromagnetic
environment.
The aerial is built into the unit as
illustrated in the dotted line. The
sensitivity of the Bluetooth communication
will improve by turning the direction of
the built-in aerial to the connected
Bluetooth device.
The communication distance shortens
when the obstacles are between the aerial
of the connected device and this unit.
Location of
built-in aerial
The following conditions may affect the
sensitivity of Bluetooth communication.
– There is an obstacle such as a human
body, 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 resulting 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 away from
the wireless LAN device.
– If this unit is used within 10 m 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 a 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,
Inc. 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.
