MendWave PEMF G20 Series

Quick Start Guide

Quick Start Guide

1. Getting Started

Step 1 — Connect the Coil

Insert the coil plug into the port on the MendWave controller and
twist it into place

Step 2 — Power On

Connect the power adapter to the PEMF device and turn the knob controller to the voltage/gauss you desire.

The display will illuminate and show the frequency Hz (top number) and duty cycle % (bottom number)

Step 3 — Position the Coil

Place the soft padded coil directly over the area you want to support. You can use it over clothing — no direct skin contact is required.

2. Choose Your Settings

Frequency (top number)

*please note: When the frequency reading shows 0.001 that is = 1 Hz; 0.010 = 10 Hz; 0.100 = 100Hz (basically, just ignore the period and that's the correct frequency.)

Understanding PEMF

*Please Note: It is normal to not feel PEMF (Pulsed Electromagnetic Field) device during treatment, as they are designed to be non-sensation, non-invasive, and silent. Lack of sensation does not mean the device is not working; the magnetic fields penetrate tissues to promote cellular repair, which is not felt like heat or vibration. *Some people can feel a warmth or a slight pulsing.


Testing Your PEMF

You can check that the device is working by using the enclosed magnet. Turn the device on and place the magnet between your finger. Hold the magnet next to or on the loop and you can feel the pulsing.*Watch the video 

 

Frequency

One of the most important factors in PEMF therapy is frequency - the rate at which these pulses are delivered.

Different frequencies can influence your body in different ways, from enhancing circulation and reducing inflammation to supporting relaxation, sleep, and overall cellular health

Frequency (Hz) determines the type of effect (calming, recovery, repair etc)

General Frequency Guide:

  • 1 to 5 Hz: Commonly used for calming and relaxation, this can be a good starting point for people ending long days or managing stress. It has a slower pace that supports the body in shifting into a more restful state.

*If you carry a lot of tension or feel wired after work, this setting may be a gentle fit.

 

  • 7 to 10 Hz: Sometimes called the recovery range, this mid-level frequency targets people looking to bounce back after physical activity or short-term soreness. Sessions using this setting might feel grounding and can help tired muscles get a bit more support.


  • 15 to 30 Hz: This range is often selected when the goal is better focus, improved alertness, or more sustainable energy. People using this frequency often report feeling clearer or more awake, which may be helpful during long shifts or low-productivity days.


Comprehensive list of Frequencies

 

Duty Cycle

The percentage of time the device is actively emitting a magnetic field ("on" time) compared to the total time of one complete pulse cycle ("on" + "off" time). It measures how much energy is delivered, with a lower duty cycle (e.g., 20%) meaning more rest time between pulses, allowing for better tissue recovery and lower intensity

  • 1 to 10% For sleep and relaxation - to prevent over-stimulation. Coil will stay mostly cool.
  • 10-20% Standard for pain and inflammation (typical sessions are 15 to 30 minutes) Coil will get warm.
  • 25 -35% Used for short sessions (5 minutes only) Targets deeper healing. Increase duty cycle for chronic, stubborn conditions or deeper tissue penetration.

FYI: At 25-35%: Coil will be noticeably warm. You can place a towel between you and the coil for cooler treatment.

  • Duty Cycle Max: 35%

Frequency & Duty Cycle Controller

How to use the frequency and duty cycle controller.

Refering to the image above:

Frequency reading is the top number and the reading of .001 is 1 Hz.

The bottom number is the duty cycle percent. 

The controller will power on when you turn on the power supply – it can take a few seconds to power up.

The green ON button is to provide output power to the loop. The word OUT will show on the display when it is on.

Frequencies: Adjustable from 1 Hz to 100 Hz

Duty Cycle: Adjustable from 1 to 35%

Gauss/Intensity

Gauss Strength: The G20 is adjustable from about 3 to 25 gauss. 

  • Gauss determines penetration (The deeper the target tissue (e.g., hip joint), the higher the necessary intensity to ensure the magnetic field reaches the area effectively.


Low Intensity (0.1–10 Gauss): Suitable for sensitive individuals, relaxation, long-term use, and daily maintenance. (Most commercial PEMF mats are pretty weak with 1 to 3 gauss)

Medium Intensity (10–100 Gauss): Effective for localized, chronic conditions and injury recovery.

*More Isn't Always Better: Higher intensity does not always equal better results; the goal is to find the "sweet spot" that triggers healing without causing discomfort – Start lower and let your body get use to it.

 How to Adjust The Gauss Strength:

Power Supply - voltage controller knob

The knob on the power supply turns the voltage up and down. *This controls the gauss level of the loops.


The strength is adjustable from about 3 to 25 gauss.

  • To lower the gauss strength, turn the voltage on the power supply down

  • To turn the gauss up, turn the voltage up

Possible Minor Side Effects:


While PEMF is safe and non-invasive, minimal reported side effects usually
result from the body adjusting to treatment, such as mild dizziness, headache, fatigue, or tingling.
These rare effects are typically temporary, resolving quickly with increased hydration or adjusted session intensity.

Precautions and Contraindications


While side effects are rare, PEMF should be avoided or used with caution in certain cases:

Medical Devices:

Those with pacemakers or other implanted devices should avoid it due to
potential interference.


Pregnancy:
Not recommended due to lack of studies.


Health Conditions:

Anyone with an implanted electronic device, active cancer, epilepsy, or those who are pregnant should avoid or consult a doctor before using PEMF.
*It's recommended that anyone with a serious medical condition should consult their doctor prior to use.


*It is recommended to drink plenty of water before and after sessions and to consult a professional if new symptoms arise.
