Why can't I hear any sound when the product is working?

This schumann resonance generator produces 7.83Hz ultra-low frequency electromagnetic field pulses, which are completely inaudible to the human ear. No sound output is normal and does not indicate a malfunction.

Does this product need to be plugged in at all times to function?

This healing frequency generator has no built-in battery and must remain connected to a power source at all times to work continuously.

Why didn't my sleep improve after using it for a while?

This frequency machine for healing is designed for daily wellness support. Individual results may vary based on sleep habits and stress levels. Many users report noticeable improvement after 3–4 weeks of regular use.

What does the middle "backlight" switch do?

Turning on the middle backlight switch brightens the display of this frequency machine. Turning it off does not affect normal operation

Why do I get no reaction from the Schumann wave detector or headphones when testing the frequency?

The frequency generator may output frequencies outside detection ranges. The Schumann wave detector works at 1–100 Hz; headphones at 1–15 kHz. If your frequency is outside these ranges, no movement (detector) or no sound (headphones) is normal.
