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
(2.4GHz) 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.
