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 (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
