What is the Bluetooth function?

The Bluetooth function enables wireless data transfer between devices that support Bluetooth wireless technology. You can transfer data between these devices at a range of up to 10 meters in an open area.
You do not need to use a cable for connection, since the Bluetooth function uses wireless technology, nor is it necessary for the devices to face one another, as is the case with infrared technology. For example, you can use Bluetooth devices in a bag or pocket.
