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

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.

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.
