Precautions
On Bluetooth communication
• Bluetooth wireless technology operates
within a range of about
10 meters (about 30 feet).
Maximum communication range may
vary depending on obstacles (person,
metal, wall, etc.) or electromagnetic
environment.
• The aerial of this unit is built into the
housing for the right ear. The sensitivity
of Bluetooth communication will
improve by placing a connected
Bluetooth device on your right side.
• The following conditions may affect the
sensitivity of Bluetooth communication.
– There is an obstacle such as a person,
metal, or wall between this unit and
Bluetooth device.
– A device using 2.4 GHz frequency,
such as a wireless LAN device,
cordless telephone, or microwave
oven, is in use near this unit.
• Because Bluetooth devices and wireless
LAN (IEEE802.11b/g) use the same
frequency, microwave interference may
occur and resulting in communication
speed deterioration, noise, or invalid
connection if this unit is used near a
wireless LAN device. In such as case,
perform the following.
– Use this unit at least 10 m (about
30 ft) away from the wireless LAN
device.
– If this unit is used within 10 m (about
30 ft) of a wireless LAN device, turn
off the wireless LAN device.
– Install this unit and Bluetooth device
as near to each other as possible.
• Microwaves emitting from a
Bluetooth device may affect the
operation of electronic medical
devices. Turn off this unit and other
Bluetooth devices in the following
locations, as it may cause an accident.
– where inflammable gas is present,
in a hospital, train, airplane, or a
petrol station
– near automatic doors or a fire alarm
• This unit supports security
capabilities that comply with the
Bluetooth standard to provide a
secure connection when the Bluetooth
wireless technology is used, but
security may not be enough
depending on the setting. Be careful
when communicating using Bluetooth
wireless technology.
• We do not take any responsibility for
the leakage of information during
Bluetooth communication.
• Connection with all Bluetooth
devices cannot be guaranteed.
– A device featuring Bluetooth
function is required to conform to
the Bluetooth standard specified by
Bluetooth SIG, and be
authenticated.
– Even if the connected device
conforms to the above mentioned
Bluetooth standard, some devices
may not be connected or work
correctly, depending on the features
or specifications of the device.
– While talking on the phone hands
free, noise may occur, depending
on the device or communication
environment.
• Depending on the device to be
connected, it may require some time
to start communication.
