You can manually test for an inflation and deflation to confirm the correct setup.
Turn the Pebble and Base ON, each showing a solid white light.
Press (do not hold) the Bluetooth button.
You will see a quick white blinking light on the Pebble and Base. The 1 minute inflation and deflation cycle will then begin. This confirms that your device is working correctly.
If you hear the pump but don't see the motion check this article to troubleshoot.
