TrueWave Frequency Generator
A portable electronic device that generates one user selected frequency between 0.001 Hz and 9999 Hz and delivers it as a low intensity signal through the included earphones or the included contact accessories.
- Any frequency from 0.001 Hz to 9999 Hz, entered on the keypad
- Digital display with a session timer that stops on its own
- Powered over USB-C, no battery to charge or replace
- Earphones, contact accessories and a hard case included
What the TrueWave is
The Amatro TrueWave is a consumer electronics product. It is a frequency generator. You choose a number on the keypad, the device produces an electrical signal at that frequency, and it runs for the length of time you set on the timer. That is the whole function of the device.
You choose the frequency
Any value from 0.001 Hz to 9999 Hz, typed on the keypad and confirmed on the display. The device produces one frequency at a time.
You choose the session length
Set the timer, press start, and the device runs until the timer reaches zero and then stops on its own. You do not have to watch it.
Two ways to connect
Through the supplied earphones, or through the supplied contact accessories placed against the skin. Both are in the box with every device.
What a frequency generator actually does
This is a plain description of the electronics. It is here so you know exactly what you are buying before you buy it.
A frequency is a number of cycles per second
One hertz, written 1 Hz, means one full cycle per second. 10 Hz means ten cycles per second. The TrueWave lets you set that number anywhere from 0.001 Hz, which is roughly one cycle every 17 minutes, up to 9999 Hz.
The circuit produces a repeating signal
An oscillator circuit generates a repeating electrical waveform at the number you entered. The display shows the value the circuit is running at, so what you set is what you see.
The signal leaves through the output
The signal goes to the 3.5 mm output for the supplied earphones, or to the terminals for the supplied contact accessories. The output is low intensity and is not user adjustable. The device has no internal battery: it draws its power from the USB-C cable, so it stays connected to a USB source while it runs.
0.001 Hz to 9999 Hz
Values in hertz, on a logarithmic scale. Every value in that span can be entered. The printed reference card in the box lists frequencies by category so you have a starting point.
Every part of the device
The housing is transparent on purpose. You can see the board, the coil and the components, which makes it easy to check nothing is loose or damaged when it arrives.
123456- CoilThe flat spiral coil printed on the board. It is the component the circuit drives.
- Digital displayFour digits showing the frequency the device is running at, and the remaining session time.
- KeypadThe row of buttons used to type a frequency, set the timer, and start or stop a session.
- USB-C power portThe USB-C port on the lower edge of the board. The device draws its power here and has no internal battery.
- Output terminalsWhere the supplied contact accessories attach. The 3.5 mm output for the earphones is on the same edge.
- Transparent housingAcrylic front and back panels held by four corner screws, protecting the board while leaving it visible.

How to use it
Five steps. The printed quick start guide in the box covers the same ground, plus how to reset the unit.
- 1
Plug it in
Connect the supplied USB-C cable to the port on the board and to any USB port or USB power adapter. The device has no battery, so it stays plugged in while you use it.
- 2
Choose a frequency
Look up a value on the printed reference card, or pick your own. Any number from 0.001 to 9999 is valid.
- 3
Enter it on the keypad
Type the number. The display confirms it. If you mistype, clear it and enter it again.
- 4
Set the session length
Use the timer buttons to set how long the session should run. The display counts down while it runs.
- 5
Connect and start
Plug in the earphones or attach the contact accessories, then press start. The device stops on its own when the timer reaches zero.
Care and maintenance
Power
Use the supplied USB-C cable with any standard USB port or adapter. Unplug it when you are not using it, and do not pull the device by the cable.
Cleaning
Wipe the acrylic with a dry or barely damp cloth. Do not submerge it, do not run water over it, and do not use solvents on the panels.
Storage
Keep it in the supplied hard case when you are not using it. Store it dry, out of direct sun, and away from anything that could press on the panels.
The cable
Keep the cable loose, do not bend it sharply at the connector, and unplug it by the plug rather than by the cord. A spare USB-C cable is easy to replace.

Every device ships with its own full set of accessories. A four device package contains four of everything below.

Questions
What does the device actually do?
It generates an electrical signal at the frequency you enter, between 0.001 Hz and 9999 Hz, and delivers it through the earphones or the contact accessories for the length of time you set. That is its full function. We do not claim any effect on the body, and this product is not intended to diagnose, treat, cure, or prevent any condition.
Can it run more than one frequency at once?
No. The device produces one frequency at a time. To use a different frequency you enter the new value on the keypad.
Can I adjust the intensity?
No. The output level is set by the circuit and is not user adjustable. The only things you set are the frequency and the session length.
Does it have a battery? How is it powered?
It has no battery. The device is powered over USB-C, through the port on the board, so it stays connected to a USB port or a USB power adapter while you use it. There is nothing to charge and nothing to replace.
Is there an app?
No. The device has no Bluetooth, no wifi and no companion app. Everything is done on the keypad. The optional Amatro VIP membership includes access to a separate application, but the device itself does not connect to anything.
Who should not use this product?
Do not use it if you have an implanted electronic device such as a pacemaker or a defibrillator, and do not use it if you are pregnant. If you have any medical condition or take any medication, speak with a qualified healthcare professional before use. It is intended for adults aged 18 and over and should be kept away from children.
Where is it made and where does it ship from?
The device is made in China. Orders are fulfilled from our network, which includes centres inside and outside the United States. For orders to the United States we aim to ensure no import duty or tax is charged to you on delivery. If you are charged an unexpected import fee, email us proof of the charge and we will review it and assist you.
How much is shipping and how long does it take?
Shipping is a flat $7.95 per order and we ship to the United States only. Orders leave the warehouse within 1 to 2 business days. Delivery is normally 10 to 15 business days after that. You get a tracking number by email when the parcel ships. Delivery times are estimates and are not guaranteed.
What if the parcel is lost or arrives damaged?
Tell us within 7 days of delivery for damage or a missing item, and within 30 days of the last tracking update for a parcel that never arrives. If you bought the optional Protected Shipping at $6.97 per device, we send a free replacement. Without it we still help you open a carrier claim and we resolve genuine cases case by case.
What is your return policy?
120 days from delivery, for a full refund of the purchase price or a replacement, whichever you prefer. Opened and used units are accepted and there is no restocking fee. Email us with your order number to get a return authorisation, then post the item within 14 days of receiving it. Refunds are issued to the original payment method within 5 to 10 business days of the return arriving.
Is this order a subscription?
Buying a device is a single charge and nothing is billed afterwards. The only recurring charge offered on this website is the optional Amatro VIP membership, which is a separate item at checkout and is switched off by default. If you turn it on, it is $0.00 for 14 days, then $89.97 charged to the same card, then $89.97 every 12 weeks, that is every 84 days, until you cancel. There is no minimum term and no cancellation fee.
How do I cancel Amatro VIP?
Email support@tryamatro.com at any time and say you want to cancel. We action it on receipt and confirm in writing. Cancelling during the 14 day trial means you are never charged a membership fee.
What appears on my card statement?
The charge appears as AMATRO. If you see something you do not recognise, contact us before contacting your bank. We can usually identify it the same day.
