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 handset
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 handset 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
other electric devices are powered on or
Bluetooth devices may cause noises or
reception failure on a TV or radio set.
Move the Bluetooth device to a place where
connection is possible when there is a
broadcast station or radio near the
Bluetooth device and the handset 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
handset.
Electromagnetic signals from the Bluetooth
device may affect the operation of electronic
medical equipment etc. As some cases may
result in accident, turn off the handset 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
failure. In this case, turn off the wireless LAN
device or keep the handset and the Bluetooth
device at least approximately 10 m away from
the wireless LAN.
