Precautions for handling the Bluetooth
device
Note the following when using the Bluetooth
device.
Note the following to make good connection.
Keep the distance between the FOMA
terminal and another Bluetooth device
within approximately 10 m with no
obstructions in sight. The distance that can
make connection may be shorter when
there are obstructions between them or
depending on the conditions of the
surroundings (such as walls or furniture)
and the structure of a building. Especially
when there is a wall or floor of reinforced
concrete between them, they may be
unable to connect with each other. Note the
above mentioned distance is not
guaranteed.
Move the FOMA terminal and another
Bluetooth device as far away as possible
from home electric appliances, AV devices,
OA devices, etc. before connection. The
Bluetooth device is liable to be adversely
affected by a microwave oven, so move it
as far away as possible from the microwave
oven while using it. Otherwise, normal
connection cannot be performed when
electric devices are powered on or
Bluetooth devices may cause noises or
reception failure on a TV or radio set (TV
images may degrade for specific channels
of UHF or satellite broadcasting).
Move the Bluetooth device to a place that
connection is possible when there is a
broadcast station or radio near the
Bluetooth device, and the FOMA terminal
cannot be connected to the device. Strong
radio waves may prevent connection
between Bluetooth devices.
Wireless connection is available with
Bluetooth device put in a bag or pocket.
However, lowering of communication speed
or noise may result when you are in
between the Bluetooth device and the
FOMA terminal.
Electromagnetic signals from the Bluetooth
device may affect the operation of electronic
medical equipment. As some cases may
result in accident, turn off the FOMA terminal
and other Bluetooth devices in the following
place.
On trains
On airplanes
In hospitals
Nearby automatic doors or fire alarms
In places such as gas stations where
flammable gas is generated
The radio interference with Wi-Fi
compatible devices
The Bluetooth devices use the same
frequency band (2.4 GHz) as wireless LANs
(IEEE 802.11b/g/n). Therefore, using the
Bluetooth device near a wireless LAN device
may cause the radio interference, lowering of
communication speed, noise or connection
fail. In this case, turn off the wireless LAN
device or keep the FOMA terminal and the
Bluetooth device at least approximately 10 m
away from the wireless LAN.
