You may switch off the ring with the button: a single short press, immediately followed by another short press, then a long press (2+ seconds) will switch off the ring. Press and hold the ring’s button for a few seconds to turn it back on. You will receive a heartbeat vibration identifying that your Ring is working now!
If you want to establish a new Bluetooth connection i.e. in case you have a new smartphone and want to connect the ring to it, you will need to switch the ring off and then switch it back on again. Immediately after switching the ring back on again, the ring will go into pairing mode. Follow the application’s instructions to make a new connection with another smartphone.
If you see ‘failed to pair’ notification, reset your ring and reconnect it to your smartphone.
