ADDITIONAL INFORMATION

Precautions

On Bluetooth communication
 Bluetooth wireless technology operates
within a range of about 10 meters (about
30 feet).
Maximum communication range may
vary depending on obstacles (human body,
metal, wall, etc.) or electromagnetic
environment.
 The antenna 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 antenna to the connected
Bluetooth device.
The communication distance shortens
when the obstacles are between the
antenna of the connected device and this
unit.
Location of
built-in antenna
 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 (about 30 ft)
away from the wireless LAN device.
– If this unit is used within 10 m (about
30 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 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.
