About Bluetooth function

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 (about
33 feet). 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.
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 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 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.
