Getting started

1

Connect the USB-C cable (5V) The device has no power button — it turns on automatically when connected. Push the cable in firmly until you feel a click. The device must remain plugged in at all times — no internal battery. Works with any USB source: wall charger, laptop USB port, or powerbank.
2

Check the display It should show Sin(Hz): 7.83. If the screen is dark — press BACKLIGHT.
3

Set the frequency (optional) Type the value on the keypad and press OK. By default the device runs at 7.83 Hz.
4

Choose the operating mode With headphones/speaker — audio mode (15–20 min per session). Without headphones — automatic silent PEMF mode (no time limit).
5

Place on a flat surface and you’re done The electromagnetic field (PEMF mode) works through furniture, walls and coverings. In PEMF mode place the device within 1.5 m of yourself.

⚠️ The screen turns off after ~1 min — this is normal (energy saving). The device is still running. Press BACKLIGHT to restore the backlight.

📄 No physical manual in the box — this is normal. All instructions, the eBook, meditation guide and frequencies are available digitally. Scan the QR code on your thank-you card.

02

Operating modes — audio and PEMF

🎧 Audio mode

Connect headphones or a speaker (3.5mm jack). The device plays frequencies as an audio signal. Recommended session: 15–20 minutes.

📡 PEMF mode (silent)

Don’t connect anything to the jack. The device automatically generates a pulsed electromagnetic field silently. Usage time: unlimited — perfect for overnight, work, or relaxation.

✓ PEMF mode is just as effective as audio mode. Many users prefer PEMF because the electromagnetic fields work at a cellular level throughout the entire body — no need to hear the frequencies.

📡 How does PEMF work? PEMF (Pulsed Electromagnetic Field) is a pulsed electromagnetic field generated silently by the device. Place the device within 1.5 m of yourself — under the bed, on your desk, or next to your chair.

⏱️ Recommended usage: once or twice a day. Audio mode: 15–20 minutes. PEMF mode: unlimited — can be used all night long.

Popular frequencies — click to copy

Frequency	Name	Use
7.83 Hz	Fundamental	Schumann Resonance (default)
14.3 Hz	2nd harmonic	First harmonic
20.8 Hz	3rd harmonic	Second harmonic
27.3 Hz	4th harmonic	Third harmonic
33.8 Hz	5th harmonic	Fourth harmonic
40 Hz	Gamma	Brain gamma waves
432 Hz	Tuning	Natural musical tuning
528 Hz	Solfeggio	MI frequency

ℹ️ If the displayed value differs slightly from what you set (e.g. 528 → 528.02) — this is normal. The device applies automatic precision calibration to adapt the signal to the electromagnetic environment. Small decimal corrections do not affect performance.

LED behaviour

Below 40 Hz — LED blinks / pulses

Above 100 Hz — LED steady on

Blinking does not indicate a fault. You can cover the device with a cloth — the waves work through any covering.

04

Headphones and audio

Connecting headphones

Connect headphones (3.5mm jack) to the audio port on the left side of the device. Push the plug in firmly until you feel a click — no visible gap.

🎧 Frequencies below 50 Hz are inaudible through headphones — a normal physical phenomenon. At 7.83 Hz you won’t hear any sound, but the device still generates an electromagnetic field via the antenna (PEMF mode).

📡 The device does not support Bluetooth — wired 3.5mm jack connection only.

Volume control

No built-in volume control. You can adjust it:

Directly on the headphones (if they have their own control)
On the Premium Vibration Speaker — hold the minus (–) icon
In the system settings of the connected device

Sound only from one side of the headphones?

1
Check the connectionPush the cable in firmly until you feel a click — no visible gap.
2
Test the headphones separatelyConnect them to a phone or laptop — check both sides.
3
Contact the sellerSend a photo of the set — you will receive a solution or a replacement.

Something not working?

The device won’t turn on — is it broken?▼

ℹ️The device has no power button — it turns on automatically when the USB-C cable is connected. No internal battery — it must remain plugged in at all times.

1
Check the USB-C connectionPush in firmly until you feel a click.
2
Try a different power sourceAnother wall charger, laptop USB port, or powerbank.
3
Try a different USB-C cableThe included cable is a standard charging cable — easy to replace.
4
Press BACKLIGHTThis lights up the screen if it went dark after 1 minute of inactivity.

The screen went dark — did the device turn off?▼

✓No. The backlight turns off after ~1 minute of inactivity — the device is still running. Press BACKLIGHT to wake the screen.

OVERRUN ERROR is displayed▼

The error appears when keys were pressed in the wrong order.

1
Unplug the USB-C cable
2
Plug back in
3
Enter a frequency and press OK

✗ To avoid the error: don’t press OK twice in a row, don’t press SET → OK, don’t press SET when no frequency is playing.

No sound from the headphones▼

1
Check the jackPush in firmly until you feel a click — no visible gap.
2
Make sure you pressed OK after entering the frequency
3
Select a frequency above 50 HzBelow 50 Hz sound is inaudible — a normal physical phenomenon. The device still generates an EM field.

The LED is blinking — is it a fault?▼

✓No — this is normal behaviour below 40 Hz. You can cover the device with a cloth if the blinking is bothersome — the waves work through any covering.

Frequency shows as 528.02 instead of 528▼

✓This is normal. The device applies automatic precision calibration to adapt the signal to the electromagnetic environment. Small decimal corrections do not affect performance.

Can I use a Bluetooth speaker?▼

✗The device does not have Bluetooth. It only supports wired 3.5mm jack connection.

Can I use the device with a pacemaker?▼

⚠️We have happy customers who use the device with pacemakers. However we always recommend consulting your doctor or cardiologist before using any device that emits electromagnetic fields.

Can I use the device if I am deaf or hard of hearing?▼

✓Absolutely! Use PEMF mode — the device generates electromagnetic fields without any sound. The field works at a cellular level throughout the entire body, not through hearing.

How is this different from listening to frequencies on YouTube or an app?▼

The device generates pure analogue electromagnetic waves — not digital approximations. YouTube and apps play digitised audio files limited by your phone or computer speakers. This device produces genuine analogue waves and offers silent PEMF mode — something YouTube and apps simply cannot provide.

How is it different than Rife's device?▼

The device uses similar electromagnetic frequency technology, but at a fraction of the cost of a Rife machine. It offers the same therapeutic range (1 Hz – 100 kHz) with both audio and silent PEMF modes.

What does the warranty cover?▼

🛡️1-year warranty covers any manufacturing defects or hardware malfunctions. If the device stops working properly within the warranty period — contact the seller and it will be replaced free of charge.

I didn’t receive a physical manual in the box▼

✓This is normal. All instructions, the eBook, meditation guide and frequency guides are delivered digitally. Scan the QR code on your thank-you card to access them.

The science of Schumann waves

What are Schumann waves?

Schumann waves are electromagnetic resonances in the space between the Earth’s surface and the ionosphere. The wavelength at 7.83 Hz is approximately 38,000 km — close to Earth’s circumference (40,000 km). The wave emitted at this frequency creates a standing wave in Earth’s cavity, generating permanent oscillations. The dominant resonance background spans 3–60 Hz, with peaks at 7.83 · 14.3 · 20.8 · 27.3 · 33.8 Hz.

History

The phenomenon was first observed by Nikola Tesla in 1899 in Spring, Colorado. It was systematically described by W.O. Schumann in 1952.

How does the device work?

The generator produces a pulsed electromagnetic field that works at a cellular level. A precision crystal oscillator ensures stable, interference-free frequency generation. These are not digital recordings or approximations — they are real electromagnetic frequencies. Range: 0.01 Hz – 100 kHz.
