Bluetooth is a short-range wireless communications technology used to communicate between devices over a distance of about 8 meters.
To connect to a Bluetooth device, you must turn on your phone’s Bluetooth radio. The first time you use a new Bluetooth device, you must pair it with the one you want to connect. Then both devices know how to connect securely to each other. After that, they connect automatically.
Turn on Bluetooth by accessing into Main menu -> “Tools” -> “Bluetooth”-> select “Turn on”.
Click “Paired devices” -> “Add new device”, the device will scan for available devices, select the device that you want to pair with.
