Vacuum RF Controls: Pressure, Suction and Relax Timers

Tabletop Cavitation Machine with Vacuum RF Home Care Setup

Start here

The rear dial and the screen timers do different jobs. The dial adjusts vacuum pressure; Suction and Relax control how long the suction and release phases last. A timer reading is not a pressure measurement.

This guide helps you identify the controls on the Litevisage tabletop configuration. It is not a treatment prescription or a source of universal beginner settings.

Tabletop Cavitation Machine with Vacuum RF

Quick answers

Bottom Line Up Front (BLUF)

  • The rear rotary dial controls vacuum pressure independently of the screen timers.
  • Suction increases in 1-second steps. Relax increases in 0.2-second steps.
  • Equal numbers on the two timers do not represent equal durations.
  • Facial care uses the dedicated Facial RF handpiece; do not substitute the body cavitation or Vacuum RF handpiece.

Three controls, three different questions

Pressure dial: how much suction is applied? The documented rear rotary control increases pressure clockwise and decreases it counter-clockwise. No numerical pressure range in kPa is supplied.

Suction timer: how long does the suction phase last? Each increase corresponds to one second.

Relax timer: how long does the release phase last? Each increase corresponds to 0.2 seconds. These control increments do not establish an appropriate setting for an individual user.

Read the units before comparing the numbers

If both timer displays read 2, the documented increments correspond to 2 seconds of Suction and 0.4 seconds of Relax. This is a unit-conversion example, not a recommended starting combination.

Increasing a timer changes cycle duration, not the rear dial position. RF energy selection is another control and should not be confused with either vacuum pressure or timing.

Continuous and pulsed RF labels do not establish EMS capability. This configuration does not document an EMS function.

Common Pitfalls When Operating Vacuum RF

Operating vacuum-assisted probes without understanding pressure calibration or timing increments often creates preventable frustration.

Fear of Petechiae and Excessive Suction Marks

Beginners often struggle with continuous vacuum pressure, leading to unwanted skin pinching or surface bruising if the handpiece lingers too long in one spot.

Confusion Over Suction vs. Relax Timers

Not understanding the difference between the 1-second suction duration and 0.2-second relaxation rhythm causes inconsistent glides and tissue fatigue.

Gel Ingestion Damaging the Internal Vacuum Pump

Using improper oil mediums or omitting the internal filter cotton allows liquid into the air line, clogging the rear suction regulator and degrading motor life.

The Evolution: From Static Suction to Pulsed Vacuum RF

Early cosmetic vacuum cups relied on static mechanical suction that held tissue continuously, requiring forceful manual pulling that caused uneven dragging. Modern tabletop consoles integrate pulsed interval solenoid valves with simultaneous bipolar RF, synchronizing 1.0-second suction steps with rapid 0.2-second releases to ensure constant glide fluidity.

Professional Perspective on Mechanical Tissue Mobilization

“Maintaining continuous applicator motion and adequate aqueous coupling is essential. Safe radiofrequency relies on uniform dermal thermal dispersion in the 113°F to 149°F window without superficial epidermal overheating.”

Before selecting a setting

Match the attachment to the intended function and area. For facial care, use only the dedicated Facial RF handpiece. The body procedure excludes the face; a facial Vacuum RF procedure is not supplied.

Confirm a treatment medium for this exact unit. Do not assume a skincare oil, massage oil or gel approved for a different device is compatible.

Use this model’s area-specific procedure, keep the applicator moving as directed and stop for pain, excessive heat or concerning symptoms. If you cannot confirm settings or suitability, resolve those questions before starting.

Control reference

Control | What changes | What it does not establish

Rear pressure dial | Vacuum pressure | A verified pressure reading in kPa

Suction setting | Suction time; 1-second increments | RF energy or vacuum pressure

Relax setting | Release time; 0.2-second increments | The same duration as an equal Suction number

Conclusion: Identify the control before interpreting its number.

Questions about this model

Answers for this configuration, rather than assumptions based on another device.

How do I calibrate the suction intensity with the rear knob?

The rear analog knob modulates physical negative pressure independently from the digital touch screen. Always start by turning the knob counter-clockwise to the lowest setting before powering on the handpiece, then slowly increase suction until a gentle, comfortable fold forms without skin discomfort.

What suction and relaxation timings should beginners use?

A balanced starting rhythm is 2.0s Suction (adjusted in 1-second increments) followed by 0.6s to 0.8s Relax (adjusted in 0.2-second increments). This rhythmic intake and release permits effortless applicator gliding toward regional lymph nodes without tugging or pinching.

Can I use the Vacuum Bipolar RF handpiece on my jawline or face?

No. The Vacuum RF and Cavitation handpieces are strictly reserved for broader body zones (abdomen, thighs, flanks). Facial contouring should exclusively use the dedicated Facial RF handpiece without vacuum suction to protect delicate facial capillaries.

Can I use slimming massage oil instead of ultrasound gel?

Do not assume general oils are suitable. You must only use a treatment medium confirmed as compatible with this exact system. High-viscosity water-soluble conductive gel (not included with the system) protects bipolar RF electrode conductivity and prevents oily residue from degrading the vacuum seals.

How often should the vacuum filter cotton be replaced?

Inspect the small filter cotton inside the probe tip before every session. Replace it immediately whenever it shows gel discoloration or dampness to prevent aerosolized fluids from entering the pump assembly.
