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 short white blinking light on the Pebble and Base. And then the 1 minute inflation and deflation cycle begins. This confirms that your device is working correctly.
If you hear the pump but don't see the motion check this article to troubleshoot.
