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 or digital camera. Bluetooth wireless technology operates within a range of about 10 meters (about 30 feet). 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 this unit
Profile is standardization of the function for each Bluetooth device specification. This unit supports the following Bluetooth version and profiles:
Communication System : Bluetooth Specification version 2.0
Compatible Bluetooth Profiles: – A2DP (Advanced Audio Distribution
Profile): Transmitting or receiving audio content of high-quality.
– AVRCP (Audio Video Remote Control
Profile): Controlling A/V equipment; pausing, stopping, starting playback, volume control, etc.
– HSP (Headset Profile)*: Talking on the
phone/Operating the phone.
– HFP (Hands-free Profile)*: Talking on
the phone/Operating the phone by hands-free.
* When you use a Bluetooth mobile
phone supported by both HFP (Hands­free Profile) and HSP (Headset Profile), set to HFP.
Notes
To be able to use the Bluetooth function, the Bluetooth device to be connected requires the same profile as the unit’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 this unit is slightly delayed from the sound played on the Bluetooth device during talking on the telephone or listening to the music.

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 right unit as illustrated in the dotted line. The sensitivity of Bluetooth communication will improve by placing a connected Bluetooth device on your right side. The communication distance shortens when the obstacles are between the aerial of the connected device and this unit.
Location of built-in aerial
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.
22
– If this unit is used within 10 m (about
30 ft) of a wireless LAN device, turn off the wireless LAN 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.
On the supplied AC power adaptor
Use the AC power adaptor supplied with this unit. Do not use any other AC power adaptor since it may cause the unit to malfunction.
Polarity of the plug
If you are not going to use this unit for a long time, unplug the AC power adaptor from the AC outlet. To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.
Others
