Precautions when using Bluetooth devices
Note the following in order to ensure a
good connection.
• Connect with another Bluetooth device
within about a 10-meter viewable
distance. Depending on surroundings
(walls, furniture, etc.) and building
structure, the connectable distance is
shorter. The connectable distance will
also be shorter if an obstacle is between
the FOMA terminal and another
Bluetooth device. Connection may be
unestablishable if your FOMA terminal
and the device are located on opposite
sides of walls containing metal rods, such
as on upper and lower storeys or in
adjoining rooms, especially in a building
made of reinforced concrete.
Also note that the above connection
distances are not guaranteed.
• Connect the FOMA terminal distanced
from other devices (electric products/AV
equipment/OA equipment, etc.) as much
as possible (since the terminal is easily
affected by a microwave oven in use,
distance the terminal as far as possible).
If the terminal is brought closer when
another device is on, it may be unable to
connect normally or may be a cause of
television and radio noise or interference
(television picture may be unclear for
particular UHF or satellite channels).
• If you cannot connect normally due to a
nearby broadcasting station, wireless
transmitter, etc. change the location of
the partner Bluetooth device. You may
not be able to connect normally if
surrounding radio waves are too strong.
• You can establish a wireless connection
while a Bluetooth device is in a bag or
pocket. However, if you body is located
between the Bluetooth device and the
FOMA terminal, decreased
communication speed or noise may
occur.
Bluetooth devices and wireless LAN (IEEE
802.11 b/g/n) use the same frequency
band (2.4 GHz). If you use the FOMA
terminal or Bluetooth device near a
device equipped with a wireless LAN,
radio wave interference may occur and
can result in decreased communication
speed, noise, a poor connection, etc. If
this happens, do the following.
• Keep the FOMA terminal and a Bluetooth
device in wireless connection at least
10 m from a wireless LAN.
• Turn off a wireless LAN when used within
10 m.
