What is Bluetooth wireless  
technology?  
Communication System :  
Bluetooth Specification version 2.0  
Bluetoothwireless 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  
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.  
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.  
* When you use a Bluetooth mobile  
phone supported by both HFP (Hands-  
free Profile) and HSP (Headset Profile),  
set to HFP.  
Bluetooth standard is an  
international standard supported by  
thousands of companies all over the  
world, and employed by various  
companies worldwide.  
Notes  
To be able to use the Bluetooth  
function, the Bluetooth device to be  
connected requires the same profile as  
the units.  
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.  
Communication System  
and Compatible Bluetooth  
Profiles of this unit  
Profile is standardization of the  
function for each Bluetooth device
