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 (30 ft).
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:
ˎ ˋ A2DP (Advanced Audio Distribution Profile): Transmitting or receiving audio
content of high-quality.
ˎ ˋ AVRCP (Audio Video Remote Control Profile): Controlling A/V equipment;
pausing, stopping, or starting playback, etc.
ˎ ˋ HSP (Headset Profile): Talking on the phone/Operating the phone.
ˎ ˋ HFP (Hands-free Profile): Talking on the phone/Operating the phone by
hands-free.
ˎ ˋ SPP (Serial Port Profile): Establishing serial communication with BLUETOOTH
device.
Maximum communication range
Use BLUETOOTH devices within 10 m (about 30 ft) (line of sight) of the system.
Maximum communication range may shorten under the following conditions.
ˎ ˋ There is an obstacle such as a person, metal, or wall between the system and
BLUETOOTH device.
ˎ ˋ A wireless LAN device is in use near the system.
ˎ ˋ A microwave oven is in use near the system.
ˎ ˋ 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.
ˎ ˋ Use the system at least 10 m (about 30 ft) away from the wireless LAN device.
ˎ ˋ If the system is used within 10 m (about 30 ft) 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.
ˎ ˋ where inflammable gas is present, in a hospital, train, airplane, or a gas
station
ˎ ˋ near automatic doors or a fire alarm
Notes
ˎ ˎ 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.
ˎ ˎ 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.
ˎ ˎ 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.
ˎ ˎ We do not take any responsibility for the leakage of information during
BLUETOOTH communication.
ˎ ˎ 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.
ˎ ˎ Noise or sound skips may occur depending on the BLUETOOTH device
connected with the system, the communication environment or the usage
environment.
