SMECL04 Adjustable Version Frequency/Volume Adj 0.01-100kHz Schumann Resonances SR Signal Generator Helps Sleep Improve Water Quality and Health

SMECL04 is a new version of Schumann wave signal generator designed and produced by SMECL. It realizes frequency and volume adjustable functions in a smaller size. Compared with the old version, it also realizes 0.01HZ-100KHZ continuous adjustment (non-eletechsup products do not have this function)

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~100KHz,
digital circuit crystal oscillator frequency reference, more stable, stronger anti-interference

1 Working voltage: DC 5V
2 Working current: 10-15MA
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(Continuously adjustable)
6 Volume Adjustable:0-3.3V
7 Signal voltage amplitude: 3.3V
8 With 3.5MM audio output
9 Size: 100*50*22MM(Mini Size)
10 Weight : 30g(Light weight)

This product has improved the following functions based on the old version:
1. Added adjustable signal Volume(Amplitude)
2. Use encoder to adjust frequency/Volume
3. 0.01HZ-100000HZ continuously adjustable
4. Surpasses the performance of the old version in a smaller size
5. Uses better 0.96'' OLED display
6. Use buttons to turn on and off the backlight

Q&A:
 
Q1:How to adjust the frequency (for example, to 100HZ)
1 Click the ''Frequency Adj'' encoder to enter the ''Input (Hz)'' menu bar
2 Click the ''Frequency Adj'' encoder several times, then the lower horizontal line enters the percentile, and rotate the encoder to 1
3 Follow the above steps to set the number to 100.00
4 Click the ''Volume Adj'' encoder to save the parameters
 
Q2:How to adjust the signal amplitude(Volume)
1 Click the ''Volume Adj'' encoder to enter the Volume menu bar
2 Rotate the ''Volume Adj'' encoder to adjust the Volume parameter
3 Click the ''Volume Adj'' encoder again to save the parameter
 
Q3:Need to save parameters even after power off?
A3:Please press and hold the ''Volume Adj'' encoder until the LCD displays ''Data Save ON''

Q4 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 ''Volume Adj'' encoder until the LCD displays ''Data Save OFF'', then power on again to restore factory settings.

Q5: How to verify the output waveform?
A5: Please use an oscilloscope to measure the ''GND/SIN'' port. You can see a pure sine wave.

Q6:How to turn off the output signal indication (LED)?
A6:Press the ''LED ON/OFF'' button to turn off the output signal indication;

Q7:How to switch off:
1 Disconnect the power
2 Press and hold the ''Frequency Adj'' encoder until the display turns off
