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 (person,
metal, wall, etc.) or electromagnetic
environment.
The aerial of this unit is built into the
right unit as illustrated in the dotted
line. The sensitivity of Bluetooth
communication will improve by placing
a connected Bluetooth device on your
right side.
The communication distance shortens
when the obstacles are between the
aerial of the connected device and this
unit.
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 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, 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.
