To adjust the volume on your device, press the larger volume button on the top of your tablet. Pressing the left button lowers the volume and pressing the right button increases the volume. This will adjust the volume of your ring.
To adjust the volumes on other settings, press the volume button and touch the downward arrow on the screen pop-up, where you can adjust the volume of the media settings (ie. sound/video) and alarm. These settings can also be adjusted using the touchscreen when the pop-up shows.
