5.1 Reconnecting Headphones
Typically, you won't need to re-pair your headphones with the Oasis Plus 2 every time, as they should automatically reconnect when both devices are turned on. If they don't, here are a few things you can try:

- Solution 2: Initiate Reconnection (Transmitter). If they still don't connect, press the Oasis Plus 2's pairing button (either "1" or "2" depending on which headphone you're trying to reconnect) once to manually initiate the reconnection process.
- Solution 3: Initiate Reconnection (Headphones). The last thing you can try is initiating reconnection on your headphones as well. You can check your headphone's user manual for directions on how to do this if necessary.
