About the Bluetooth 
wireless technology

Bluetooth wireless technology is a short-
range wireless technology that enables 
wireless data communication between 
digital devices. Bluetooth wireless 
technology operates within a range of about 
10 meters (33 feet).
You do not need wires to get connected as 
you do with a USB connection, and you do 
not need to place the devices face to face as 
you do with wireless infrared technology. 
Bluetooth wireless technology is a global 
standard supported by thousands of 
companies. These companies produce 
products that meet the global standard.

Check the websites for the latest 
information about compatible Bluetooth 
devices with URLs listed under “About 
support information” (page 118).

About the Bluetooth 
functions of the

each Bluetooth device specification. This 
receiver supports the following Bluetooth 
version and profiles:

• To be able to use the Bluetooth function, the 

Bluetooth device to be connected requires the 
same profile as the receiver’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 receiver is 
slightly delayed from the sound played on the 
Bluetooth device during listening to the music.
