With timing shutdown, signal light brightness adjustment, screen backlight brightness adjustment. All setting parameters can be automatically saved, and there is no need to set them in the next startup Built-in battery:Built-in rechargeable battery, free from the constraints of power cords, allowing flexible placement by the bedside, on a nightstand, or office desk Schumann Resonance:The Schumann resonance spectrum is in the ELF band with a frequency of about 8Hz. The frequency of the hippocampus in the mammalian brain is also 7.83 hertz. Therefore, Schumann resonance is called "the brain wave of the earth" and "Nature's Frequency". Lightning anywhere on the earth will excite the electromagnetic oscillation of the resonant cavity and generate natural electromagnetic waves, that is, Schumann waves, which are about 8HZ
