1. When connecting to a device for the first time, there will be a pop-up window for you to confirm pairing. Select "pair". If you accidentally select "cancel", you need to delete the earbuds from the device's Bluetooth history and re-pair Liberty 2. 

2. If you have paired the earbuds with only one device:
  Stereo Mode: Take both earbuds out from the charging case and they will automatically enter stereo mode.
  Mono Mode: Put one earbud into the charging case and close the lid, then use the other one. If that doesn't work, please confirm step 1 has been done successfully.
  When you switch from stereo to mono, the audio will pause. Within 2-4 seconds, Liberty 2 earbuds will connect again so press play to continue listening. 
3. If you paired the earbuds with several devices before, disable the Bluetooth on other devices and connect the earbuds to the device you want to use. If the earbuds do not connect to the device automatically, you can manually select the earbuds from the device's Bluetooth menu. After this, follow the same method in step 2 to switch between stereo and mono.
