If the video on your phone is not a complete circle, your SmartCheck device may not be properly aligned. Use the red indicator in the app to help you properly position the device over the camera lens.  Align the arrows on the device’s Alignment Feature with the white, vertical line in the app. You know you have the correct  alignment when the visible area in the middle of the screen is a complete circle. You may also need to check the specula tip. If you find debris, throw the specula tip away and attach a new one. If you see any irregularities, please contact our Customer Care Center at 800-458-1635.
