Hi, it's easy but not very intuitive.
1. Enter Functions;
2. Enter Audio In;
3. Enter Bluetooth;
4. Enter Bluetooth Audio;
5. Set to On;
6. Enter Pairing;
7. Go on your device and pair with CASSIO Privia;
8. Play something to test;
9. On your device, disconnect from bluetooth, you don't need to turn off bluetooth, just disconnect from CASSIO Privia;
10. Enter Pairing again;
11. On the other device pair with CASSIO Privia;
12. Play something to test;
13. On your second device disconnect from the CASSIO Privia;
14. Go back to the first device and just connect with CASSIO Privia;
15. Play something;
You only need to pair with each device once and disconnect before trying to connect with another.
You can pair up to eight different devices.
