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.
Location of
built-in aerial

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

• 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.

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.
