4. Go to the Bluetooth Settings  Page to Continue with How to Pair Sony Speaker SRS-XB21 

Our Bluetooth Settings screen displays as follows. Note that our Bluetooth is ON here. But since our SRS-XB21 is currently OFF, then it is not in Bluetooth discovery mode. Thus it does not show up in the Bluetooth devices list. Also, we don’t see it since we’ve never paired this speaker with our mobile device before.

But since our tablet does not know about the SRS-XB21, it will not pair with it automatically.

So to see your XB21 on your device, place it into Bluetooth discovery mode. To do that, press the Power button. Then release it when you hear the rising pitch beep sequence.  Also the speaker announces, “Bluetooth pairing,” in a lady’s voice.

In addition to the voice announcement,  the Bluetooth Status lamp begins flashing fast.
