Precautions about handling Bluetooth devices
Note the followings when using Bluetooth devices.
z Note the followings 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 within which you 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, floor
or ceiling 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. Bluetooth devices are liable
to be adversely affected by a microwave oven, so move
them as far away as possible from the microwave oven while
using them. 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 other party's Bluetooth device to a place where
connection is possible when there is a broadcast station,
radio, etc. 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 devices 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.
z Electromagnetic signals from Bluetooth devices 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 places.
„ On trains
„ On airplanes
„ In hospitals
„ Near automatic doors or fire alarms
„ In places such as gas stations where flammable gas is
generated
Radio interference with Wi-Fi compatible devices
z The Bluetooth devices use the same frequency band (2.4
GHz) as wireless LANs (IEEE 802.11b/g/n). Therefore, using a
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 other party's Bluetooth
device at least approximately 10 m away from the wireless
LAN.
