What Do M1, M2, M3 and M4 Mean on a Cavitation Machine?

Elevaure| Editorial Team October 07, 2026

⚡ Bottom Line

Mini Cavitation Machine with Vacuum & RF for Body Care provides four selectable 40kHz cavitation pulse patterns: M1 runs 3 sec on / 3 sec off, M2 runs 2 sec on / 2 sec off, M3 runs 1 sec on / 1 sec off, and M4 runs 0.5 sec on / 0.5 sec off. These settings describe pulse timing, not a documented power ranking. Select the mode according to the operating guidance, treatment area, and acceptable comfort level.

CAVITATION PULSE MODE GUIDE

Last Updated: September 30, 2026

Cavitation pulse modes are selectable timing patterns that determine how long the 40kHz cavitation function operates and pauses during each cycle. This machine provides four patterns labeled M1 through M4.

On the Elevaure Mini Cavitation Machine, M1–M4 are the four selectable pulse patterns for the 40kHz cavitation function. The supplied product materials specify the on/off timing for each mode but do not assign a higher or lower power ranking to M1, M2, M3, or M4. The same labels are used elsewhere on the machine for RF and EMS, where the mode meanings are different, so users should confirm that Cavitation is the selected function before interpreting M1–M4.

Why M1, M2, M3 and M4 Are Easy to Misread

Problem

Users often see M1–M4 on the control screen and assume the numbers automatically represent four fixed intensity levels.

Cause

The machine uses the same M1–M4 label structure for different functions, but the timing definitions change by function. For 40kHz cavitation, the labels describe on/off pulse timing; for body and face RF/EMS, M1 and M2 are RF modes while M3 and M4 are EMS modes.

Mechanism

The cavitation settings change the duration of each operating and pause interval: M1 is 3 sec on / 3 sec off, M2 is 2 sec on / 2 sec off, M3 is 1 sec on / 1 sec off, and M4 is 0.5 sec on / 0.5 sec off.

Solution

Select the Cavitation function first, then use the documented M1–M4 pulse timing according to the treatment guidance and acceptable comfort level. Begin at the lowest energy or intensity setting, keep the treatment head moving, and use the required treatment medium.

The Same M1–M4 Labels Can Mean Different Things

Why Cavitation M1–M4 Settings Are Easy to Misread

Seeing four numbered modes can make a simple setting screen feel more complicated than it is. The key is to read M1–M4 as documented operating patterns, not as an automatic strongest-to-weakest scale.

On this machine, M1–M4 are function-specific. In 40kHz cavitation they describe pulse timing, while body and face RF/EMS use the same labels for different operating patterns.

The easiest way to avoid confusion is to match the M1–M4 label to the function you selected. For 40kHz cavitation, the four choices are defined by different on/off pulse timings. For body and face RF/EMS, the labels describe different RF or EMS patterns instead. This distinction matters because choosing a numbered mode without checking the active function can lead to the wrong interpretation of the setting.

Assuming M1 Automatically Means the Strongest Setting — The M1 label does not, by itself, establish a highest-to-lowest power ranking. For this machine's 40kHz cavitation function, M1 is specifically defined by its 3-second on and 3-second off pulse timing.
Confusing Cavitation M1–M4 With RF and EMS M1–M4 — The same M1–M4 labels appear in other functions, but they do not mean the same thing. For body and face RF/EMS, M1 is continuous RF, M2 is pulsed RF, M3 is pulsed EMS, and M4 is pulsed EMS with a shorter cycle.
Treating Pulse Timing Like a Standalone Treatment Plan — Choosing M1, M2, M3, or M4 is only one part of the setup. The supplied guidance also requires the appropriate treatment medium, a suitable treatment area, a low starting energy or intensity, continuous movement of the treatment head, and attention to comfort.

What Research Says About Cavitation and RF — and What It Does Not Say About M1–M4

Peer-reviewed studies provide general context for ultrasound cavitation and radiofrequency-based body contouring, but they do not establish a universal M1–M4 intensity ranking or validate the exact pulse timings used by this home device. A human-tissue study by Daniele Bani and colleagues reported histological and ultrastructural effects associated with ultrasound-induced cavitation and described transcutaneous ultrasound cavitation as a promising noninvasive technology. A separate clinical study by Samantha Y. N. Shek and colleagues evaluated a specific non-thermal focused ultrasound plus radiofrequency device, which is a different technology from this machine's 40kHz cavitation mode. Therefore, the M1–M4 meanings on this product should be taken from the supplied operating specifications rather than inferred from unrelated clinical protocols.

"This study further strengthens the current notion that noninvasive transcutaneous ultrasound cavitation is a promising and safe technology."
Daniele Bani et al.Authors of a peer-reviewed study on ultrasound-induced cavitation

"With the addition of radiofrequency energy, the temperature of the adipose tissue is raised before focused ultrasound is applied."
Samantha Y N Shek et al.Authors of a peer-reviewed clinical study of combined focused ultrasound and radiofrequency

Peer-reviewed literature provides modality-level context only; the exact M1–M4 pulse definitions come from the product's supplied operating specifications.

How M1–M4 Are Defined by Function

40kHz Cavitation M1–M4	Body & Face RF/EMS M1–M4

Mode	40kHz Cavitation	Body & Face RF/EMS
M1	3 sec on / 3 sec off	Continuous RF
M2	2 sec on / 2 sec off	RF 0.5 sec on / 0.5 sec off
M3	1 sec on / 1 sec off	EMS 0.5 sec on / 0.5 sec off
M4	0.5 sec on / 0.5 sec off	EMS 0.1 sec on / 0.1 sec off

Bottom line: Cavitation M1–M4 are pulse-timing choices for the 40kHz cavitation function. The same labels mean something different in the RF/EMS functions, so mode numbers should always be interpreted together with the selected function.

First-Time Users Choosing a Cavitation Pulse Mode

You are using the 40kHz cavitation function for the first time and want to understand what the four numbered modes actually change before beginning a body-care routine.

Unsure whether M1 means strongest
Confused by four pulse options
Not sure which timing applies to cavitation
Worried about starting too aggressively

Confirm that the Cavitation function is selected, then use the documented M1–M4 pulse timing table. Follow the supplied guidance to apply the required treatment medium, hold the applicable head at approximately 90°, begin at the lowest energy or intensity, increase gradually according to tolerance, and keep the treatment head moving. Do not treat the M1–M4 labels as a documented power ranking.

Switching Between Cavitation and RF/EMS Functions

You have finished one routine and switch the machine to another function, then notice that M1–M4 appear again on the control screen.

Same M1–M4 labels appear in another function
Unsure whether the numbers keep the same meaning
Risk of copying a cavitation setting to RF or EMS
Need a quick way to read the control screen

Treat the active function as the first piece of information. In 40kHz cavitation, M1–M4 represent pulse timing. In body and face RF/EMS, M1 is continuous RF, M2 is pulsed RF, M3 is pulsed EMS, and M4 is a shorter pulsed EMS cycle. Re-check the selected function before interpreting the mode number.

Peer-Reviewed Experimental Study Journal of Cosmetic and Laser Therapy / PubMed (PMID: 25289235)

Daniele Bani and colleagues examined histological and ultrastructural effects associated with ultrasound-induced cavitation in human skin adipose tissue. The paper provides modality-level evidence and describes noninvasive transcutaneous ultrasound cavitation as a promising technology, but it does not validate this specific home machine or its M1–M4 pulse timings.

Peer-Reviewed Clinical Study Journal of Cosmetic and Laser Therapy / PubMed (PMID: 26352171)

Samantha Y. N. Shek and colleagues evaluated a specific non-thermal focused ultrasound and radiofrequency device for noninvasive body contouring in an Asian study population. The study is useful for understanding that ultrasound and RF are distinct energy modalities, but its device, parameters, and clinical protocol should not be mapped directly onto this product's 40kHz cavitation M1–M4 settings.

M1 = 3 sec on / 3 sec off
M2 = 2 sec on / 2 sec off
M3 = 1 sec on / 1 sec off
M4 = 0.5 sec on / 0.5 sec off

What do M1, M2, M3, and M4 mean on a cavitation machine?

On this 40kHz cavitation machine, M1–M4 are four pulse-timing patterns rather than a universal strongest-to-weakest scale. M1 is 3 seconds on / 3 seconds off, M2 is 2/2 seconds, M3 is 1/1 second, and M4 is 0.5/0.5 second.

What does M1 mean on a 40kHz cavitation machine?

M1 means 3 seconds on and 3 seconds off for the 40kHz cavitation function. It describes the pulse timing of the ultrasonic output; the supplied specifications do not define M1 as the strongest or highest-power setting.

What does M2 mean on a cavitation machine?

M2 means 2 seconds on and 2 seconds off for the 40kHz cavitation function. It is a shorter pulse cycle than M1, but the product specifications do not establish a simple M1-to-M4 power ranking.

What does M3 mean on a 40kHz cavitation machine?

M3 means 1 second on and 1 second off for the 40kHz cavitation function. The setting changes the pulse timing pattern, so it should not be described as a clinically proven stronger or weaker mode without supporting data.

What does M4 mean on a cavitation machine?

M4 means 0.5 seconds on and 0.5 seconds off for the 40kHz cavitation function. It is the shortest documented cavitation pulse cycle on this machine, but shorter timing should not automatically be treated as a higher or lower energy level.

Does M1 mean the strongest setting on a cavitation machine?

No, M1 should not automatically be interpreted as the strongest setting. For this machine, M1–M4 define cavitation pulse timing only. The supplied guidance instead says to begin at the lowest energy or intensity and increase gradually according to tolerance.

Are cavitation M1, M2, M3, and M4 the same as RF and EMS M1, M2, M3, and M4?

No, the labels are function-specific. In 40kHz cavitation, M1–M4 describe pulse timing. In body and face RF/EMS, M1 is continuous RF, M2 is pulsed RF, M3 is pulsed EMS, and M4 is a shorter pulsed EMS cycle.

Which M1–M4 cavitation mode should a first-time user start with?

A first-time user should follow the supplied guidance to start at the lowest energy or intensity and increase gradually according to tolerance rather than choosing a mode based on its number alone. Confirm the Cavitation function, use the required treatment medium, hold the applicable head at about 90°, and keep it moving.
