This product not only outputs a 7.83Hz Schumann wave, but also allows frequency adjustment within the range of 0.001Hz to 200kHz. It features an LCD TFT display for enhanced stability and stronger anti-interference capabilities.

New Features:

1. Timer

2. Frequency retention after power failure

3. Overcurrent and overvoltage protection

The Schumann Wave operates without producing any sound. An external speaker can be connected via a 3.5mm audio jack to listen to different frequencies. It works by improving the spatial environment, promoting relaxation, enhancing the body's perception of sound and images, improving health, increasing work efficiency, and relieving mental stress. It uses a digital circuit crystal oscillator frequency reference, resulting in higher stability and stronger anti-interference capabilities.

1.How to change the frequency: Directly enter the frequency and then press"SET" to complete the setting For example, press [7][.][8][3], then press [SET], you can set to7.83Hz, and the setting range is 0.001Hz~200KHz.

2.Timer setting function: Press the “clock icon” once to set a 1-hour timer, press twice to set a 2-hour timer. Long press to turn off the timer.

3.Frequency save function on/off: To enable the power-off save function, press and hold the "SET" button until the LCD screen displays "Data Save ON" indicating successful。

frequency saving.To disable the power-off save function, press and hold the "SET" button until the LCD screen displays "Data Save OFF" indicating frequency saving has been canceled。

4.LCD TFT display brightness settings: Each press of the "light bulb icon" increases the screen brightness by one level; after one cycle, the screen brightness will return to the lowest level.

5.To revert to the original frequency: For example, type [7][.][8][3], then press [SET] to confirm the frequency, and then press and hold [DEFINE] until "Define Success" is displayed. Even if you set a different frequency, pressing [DEFINE] will revert you to the original "Define Success" frequency
