What is Bluetooth wireless
technology?
Bluetooth wireless technology is a short-range wireless
technology that enables wireless data communication
between digital devices, such as a computer and digital
camera. Bluetooth wireless technology operates within a
range of about 10 metres.
Connecting two devices as necessary is common, but
some devices can be connected to multiple devices at the
same time.
You do not need to use a cable for connection, nor is it
necessary for the devices to face one another, such is the
case with infrared technology. For example, you can use
such a device in a bag or pocket.
Bluetooth standard is an international standard supported
by thousands of companies all over the world, and
employed by various companies worldwide.
Communication System and Compatible
Bluetooth Profiles of the system
Profile is standardisation of the function for each
Bluetooth device specification. The system supports the
following Bluetooth version and profiles:
Communication System:
Bluetooth Specification version 2.1 + EDR*
Compatible Bluetooth Profiles:
– A2DP (Advanced Audio Distribution Profile):
Transmitting or receiving audio content of high-
quality.
– AVRCP 1.3 (Audio Video Remote Control Profile):
Controlling the sound volume.
* Enhanced Data Rate
Maximum communication range
Use Bluetooth devices within 10 m (line of sight) of the
system.
Maximum communication range may shorten under the
following conditions.
– There is an obstacle such as a person, metal, or wall
between the system and Bluetooth device.
– A wireless LAN device is in use near the system.
– A microwave oven is in use near the system.
– A device that generates electromagnetic radiation is
in use near the system.
Interference from other devices
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 the
system is used near a wireless LAN device. In such a case,
perform the following.
– Use the system at least 10 m away from the wireless
LAN device.
– If the system is used within 10 m of a wireless LAN
device, turn off the wireless LAN device.
Interference to other devices
Microwaves emitting from a Bluetooth device may affect
the operation of electronic medical devices. Turn off the
system 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 gas station
– near automatic doors or a fire alarm
Notes
 To be able to use the Bluetooth function, the Bluetooth
device to be connected requires the same profile as the
system's.
Note also that even if the same profile exists, devices
may vary in function depending on their specifications.
 Due to the characteristic of Bluetooth wireless
technology, the sound played on the system is slightly
delayed from the sound played on the Bluetooth device
during talking on the telephone or listening to the
music.
 This system 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.
 A device featuring the 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.
 Noise or sound skips may occur depending on the
Bluetooth device connected with the system, the
communication environment or the usage environment.
