Bluetooth

TM

 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.

Profile is standardization of the 

function for each Bluetooth 

device specification. This 

product supports the following

 To be able to use the Bluetooth 

function, the Bluetooth device to be 

connected requires the same profile 

as this product’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 product is 

slightly delayed from the sound 

played on the Bluetooth device 

during listening to the music or 

talking on the telephone.
