The RF heads should gradually feel warm during use. The Vacuum RF head may also warm when the RF function is active. The 80K cavitation head can generate some warmth, but it may feel less noticeable than the RF heads. Please make sure the timer and energy level are set above 0 and use enough conductive gel. If the RF heads remain completely cold after several minutes of use at a moderate setting, please stop using the machine and contact **[service@freyara.com](mailto:service@freyara.com)** with your order number and a short video so we can check it for you.  

If you have epilepsy, we do **not recommend using this machine without approval from your doctor**, especially the EMS/microcurrent functions. Please consult your healthcare provider before using any of the treatment modes to confirm they are safe for your specific condition.  

Bonjour, ne vous inquiétez pas, nous prendrons en charge ce coût. 

The energy of the radio head is 3MHZ 

40K cavitation operates at a frequency of 40,000 times/second. 80K can emit twice as many ultrasound waves. 80K cavitation slimming machines operate at a higher frequency than 40K cavitation machines, making less noise, and the probe can generate heat. The choice of cavitation frequency depends on the desired treatment effect and the thickness of fat in the area to be treated. But 40K low-frequency ultrasound waves are more suitable for dissolving deep and stubborn fat. 

RF stands for Radio Frequency, which refers to an electric current (alternating current) between the positive and negative electrodes whose magnitude and direction change periodically. The electric and magnetic fields generated by the current generate electromagnetic waves, and the period of this electromagnetic wave fluctuation is between 300KHz and 300GHz (300,000 times/second to 300,000,000,000,000 times/second). 

Laser plate is only laser beads, tied to the skin without feeling, is the universal laser wavelength to assist in weight loss, but the microelectronic plate is actually a microelectronic laser plate, not only laser beads, but also microelectronic function, contact with the skin there is a crunchy massage sensation, eMs function is also on the previous operation of the leftover products to enhance the absorption effect . 

Electrical muscle stimulation, also known as EMS, is an ideal treatment for toning muscles and tightening skin. The procedure uses microcurrents to stimulate muscles to make them stronger, tighter, and thinner. This causes the muscles to fill in loose skin, making the skin smooth and firm. EMS treatments make muscles burn more fat. 

Suitable for multiple parts of the body, commonly used in: abdomen, waist, buttocks, thighs, upper arms and other fat accumulation areas. The radio frequency probe can also be used on the face, neck and around the eyes to improve sagging and fine lines. Note: Cavitation heads and vacuum suction heads can only be used on the body, not on the face or bone protrusion areas. 

The following usage plan is recommended: Duration of each session: about 20-60 minutes per area, adjusted according to the size of the area and the user's tolerance. Frequency: 1-2 times a week, with at least 7 days between each area to allow fat metabolism and skin recovery. Treatment cycle: It is recommended that the full course of treatment is 6-12 times, and the cycle is 6-12 weeks. Usually, significant changes begin to be seen after the 3rd-6th time.
