The OMbox will vibrate in 4 instances:
1. The OMbox will vibrate once if you plug your USB cable into your OMbox then into a power source. This indicates the OMbox has woken up from hibernate or sleep mode and is charging.
2. The OMbox will vibrate once if you unplug it from the micro USB cable and power source. Wait approximately 5 seconds. This indicates your OMbox has detected a USB disconnection, has rebooted, and is ready for Bluetooth connection.
3. The OMbox will vibrate once if you double tap it when it is in sleep mode. This indicates it has woken up from sleep mode and is ready for Bluetooth connection.
4. The OMbox will vibrate twice when it starts recording your biometrics. Once you put on your OMbra, wake up the OMbox by double tapping it and clip it to your OMbra. Wait about 20 seconds, it will vibrate twice.
