SMSPN06 7.83Hz Earth HeartBeat Schumann Resonanace 0.01Hz~9999Hz Frequency Signal Generator Earth Heartbeat Signal Booster

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.

This product can not only output 7.83Hz Schumann wave,
but also can adjust the frequency within the range of 0.01Hz~9999Hz,
A high-speed DAC can generate a pure sine wave signal

1 Working voltage: DC 5V
2 Working current: 13-17MA
3 Power interface: Type-c(Support TYPE-C TO TYPE-C power supply)
4 Default frequency: 7.83Hz

How to use:
Connect to TYPE-C power supply, the digital tube displays 7.83, and the board will automatically emit 7.83HZ Schumann wave

Q&A:
Q1:How to adjust the frequency
1 When powered on, the digital tube displays the frequency. Press the ''SET'' button, the last decimal point flashes, and the setting mode is entered.
2 Press the ''++''/''--'' button to increase or decrease the frequency. Long press to speed up the adjustment.
3 After setting the frequency you need, press ''SET'' again to exit the setting and save the parameters.

Q2:Need to save parameters even after power off?
A2: Please press and hold the ''++'' Button until the LED displays ''S-N''

Q3 How to restore factory settings:
1 Normally, power on again to restore default settings.
2 If the power-off save function is enabled, please press and hold the ''++'' Button until the LED displays ''S-F'', then power on again to restore factory settings.

Q4: How to turn off the digital tube?
A4:Press and hold the ''--'' button until the digital tube displays ''S-P''. The digital tube will automatically turn off after 10 seconds.

Q5 Why does the digital tube automatically turn off after 10 seconds?
This is because the energy saving mode is turned on. Press and hold the ''--'' button until ''N-P'' is displayed.

Q6: How to verify the output waveform?
A6: Please use an oscilloscope to measure the ''GND/SIN'' port. You can see a pure sine wave.
