You're holding something one-of-a-kind — this is a custom-built unit, so there's nothing else quite like it out there. Comparable devices typically run $150–$250 online, so you're getting real value here.

Here's how to get started:

1. Plug it into the converter, then plug that into the wall. It's on when it's plugged in — no on/off switch, and it won't hold a charge, so keep it plugged in while you use it.

2. It'll power on at 7.83Hz, the Schumann Resonance — often called "the earth's heartbeat." It's a lovely one to just let run in the background for grounding, in your body and your space.

3. Want to try a different frequency? Above each small button is a number, and "OK" is at the end. Punch in your number, hit OK, and you're set. (Example: 639Hz is a favorite for heart chakra, joy, and connection.) You'll find the full list on the cards in your box, or on the website.

4. If you see "OVERRUN" pop up, no worries — just re-enter the numbers and hit OK again, or unplug and plug it back in to reset.

5. There's a nightlight switch on the right side of the unit — slide it up or down.

6. Want to actually hear the tone? There's a port on the side for a headset or speaker, so you can listen to the pure tone of whatever frequency you've chosen.

A couple of good-to-knows: it won't interfere with your other electronics, and the frequency range runs from 0.1 all the way up to 99,999Hz, so there's a lot of room to explore.
