Schumann Sine Wave Resonance Generator
Schumann wave itself is not directly acting on the sound or video products to improve the quality of sound quality, but the role of the space environment, people's physical and mental relaxation, improve the body's perception of sound and images, improve the health of the human body to improve the efficiency of work, mental stress also have a better effect.
How to change the frequency:
Directly enter the frequency and then press OK to complete the setting
For example, press [7][.][8][3], then press [OK], you can set to 7.83Hz, the default power-on output is 7.83Hz, and the setting range is 0.01~100KHz

Product had no instructions and add .86 when I typed in 728. Why did it show 728.86?Please tell me where I can find directions.

I am returning this item. Not sure if it was producing the desired effects. There’s no easy way to test.

Just received it today so I’ll come back later and update. So far, it took a while to get here, no instructions and the only word in English is OK. So hopefully putting in my frequency and hitting ok works. Tried to find manual online and no luck

It took some time to figure this out as there were NO DIRECTIONS. Everything I learned on the web, don't order this unless you REALLY understand frequencies and have a speaker and cable that will work with it.

I’m wanting to know if anyone else is having this problem, I go to change frequency to 432 and press ok and it comes up 432.52 and when I put in another frequency and press ok it adds on a .08 at the end of the number. Has anyone experienced this issue and do you know why??? Thank you ahead of time.

Worked great for about 2 months. Now the 1 2 3 and 4 buttons don't respond.

I used it one day before work, and I found that my mind was very clear, which effectively relieved my stress at the time.
