UClear units need to be paired to the main Bluetooth on your phone and not just to the application. To pair the UClear unit to your phone's main Bluetooth, first put the UClear unit into Bluetooth pairing mode by turning it on, and then hold both volume buttons for 2 seconds and the light should start flashing blue and red. From there, you should see the selection pop up on your phone's main Bluetooth settings (some devices may need to 'search' for new pairings as they may not pop up right away. For example, if you have a Motion Infinity system, you should see the selection "MOTION INFINITY" show up).
If you see your devices name show up but it has 'BLE' on the end, do not select this option for the main Bluetooth. It should only show MOTION INFINITY, MOTION 6, or MOTION 4 LITE.
