Description:
This product not only can output 7.83Hz SchumannWave, but also can adjust the frequency in the range of 0.01Hz-100KHz, the digital circuit crystal oscillator frequency reference, more stable and strong anti-interference.
This is a new version of eletechsup's Schumann Wave adjustable signal generator, which uses a low-temperature drift crystal oscillator and a high-precision DAC dedicated chip. It can accurately output frequency and pure sine wave.
With Acrylic Shell Version :
1 Working voltage: DC 5V (DC 4-15V)
2 Working current: 9-14MA
3 Power interface: Type-c(Support TYPE-C TO TYPE-C power supply)
4 Default frequency: 7.83Hz
5 Adjustment range: 0.01Hz~100000Hz Pure Sine Wave
6 Signal voltage amplitude: 3V
7 With 3.5MM audio output
8 With acrylic shell
9 Size: 155*105*26MM(With shell)
10 Weight : 197g(With shell)
For more information please Google ''Schumann Resonance''.
(Uses TYPE-C power supply and supports all TYPE-C power supplies.
Note : Since TYPE-C cables are now widely used, no additional TYPE-C power supply cables are provided.)
Q&A:
Q1:How to change the output frequency?
A1:Press the ''0-9'' and '.' buttons to enter the value, and press the OK button to confirm. If the input is wrong, press the SET button to re-enter.
For example, press [9][.][7][1], then press [OK], you can set to 9.71Hz, the default power-on output is 9.71Hz, and the setting range is 0.01~100KHz(Note: Not all frequency points can be set)
Q2:Need to save parameters even after power off?
A2:Please press and hold the ''SET'' button until the LCD displays ''Data Save ON''
Q3: How to verify the output waveform?
A3: Please use an oscilloscope to measure the ''GND/SIN'' port. You can see a pure sine wave.
Q4: How to turn off the LCD backlight?
A4:Short press the ''BACKLIGHT'' button to turn off the LCD backlight; short press the ''BACKLIGHT'' button again to turn on the LCD backlight
Q5:How to turn off the output signal indication (PWR LED)?
A5:Long press the ''BACKLIGHT'' button to turn off the output signal indication; long press the ''BACKLIGHT'' button again to turn on the output signal indication.
Q6:LCD does not display correctly after power on?
A6:Please press the RES button briefly and power on again

Love that it works without a speaker, no need to hear tones. But you could. Bare bones but solid build. Only thing is it adds appx. .5 frequency add to custom tones other than default Schuman frequency. So for instance 528 frequency setting becomes 528.54, quirky but I don't believe the slight difference will diminish effects for any frequency value you program in. Just type in a frequency and finish hitting the "ok" button. Buttons seem solid for long life. I believe it's always on weather you switch the screen on or not. So at night after you set the frequency (turn off) and the bright screen won't bother you, cause it is very bright. The antenna I believe if stretched out is appx 6 meters long. Giving a good range. But keep it close to effect whole body. I believe the frequency goes out about 3 to 4 feet. I use 432 and 528 frequency mostly.

It doesn't make any sound. The only indication that it's doing anything is the red flashing light. I don't feel anymore rested than usual. With that said though, I wear an Apple watch and since sleeping with this device on, my HRV has increased considerably. My HRV was low, in the 20s, and now it hovers between 65-80. That's a a considerable improvement.

Doesn’t work! Have tried multiple troubleshooting methods. Arrives without instructions. Immediately contacted seller for a refund. They never sent a label. Contacted Amazon a week later and they were no help. Refunded me .01 years a penny! Junk! Throw it out. A complete waste of money. Don’t bother purchasing.

It seems to be working for the frequency I have it set for. 2170 hertz. Seeing some improvements. Keep it within 4ft. Or get a speaker to resonate the room.

There is a little chip out of the epoxy protective case other than that they all work great

This product is likely fraudulent because it does not produce any EMF at all. It seems that the spiral antenna is just, for show and has no current running through it. Using an EMF reader, it was not able to pick-up any frequencies. I tried with many frequencies, including 1Hz with no detectable EMF output. I tried with multiple power inputs with no success. I tested the AUX output and found that it wasn’t producing anything either.Perhaps my unit is defective but I’m returning it.
