ADDITIONAL INFORMATION
Precautions
On Bluetooth communication
Bluetooth wireless technology operates
within a range of about 10 metres.
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.
