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 m.
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 3.0
Compatible Bluetooth Profiles:
A2DP (Advanced Audio Distribution Profile): Transmitting
or receiving audio content of high-quality.
AVRCP (Audio Video Remote Control Profile): Controlling
the volume.
HSP (Headset Profile): Talking on the phone/Operating the
phone.
HFP (Hands-free Profile): Talking on the phone/Operating
the phone by hands-free.
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.
