The Terra Station requires that your Bluetooth is enabled on your smartphone during setup. This is the same process as you would go through to turn on Bluetooth to use wireless earbuds/headphones, wireless speakers and other devices.

Simply go to system settings and select Bluetooth, and then make sure the toggle is switched to "On".

Shortcut: On any screen, including the lock screen, just swipe from the top right corner down to the center of the screen. This brings you to the quick settings screen, where you can turn Bluetooth on or off with by pressing the symbol.

Open your phone's Settings app, then navigate to Connected devices or Connections, and select Bluetooth. Then toggle the switch to the "On" position to enable Bluetooth.
