Brightness Down / Brightness Up – Adjust the hoop to a comfortable brightness level. Lower brightness levels use less power so your hoop will glow longer on a single charge. A lower brightness level is also less intense if the hoop is used in a very dark environment.
When the top brightness level is reached, the hoop will flash red.
When the bottom brightness level is reached, the lights will turn off. In this case, the hoop will still be using power and slowly draining the battery. Use the hardware switch to turn the power off completely.
