The depth of radio frequency is usually between 2 and 3 mm, mainly targeting the dermis and subcutaneous layer of the skin. As for all technical parameters, they usually include frequency, power setting, working mode, etc. For specific technical parameters, you can check the product manual. 

Ultrasound Cavitation Technology is Silent The device operates at a 40kHz frequency, which is beyond the range of human hearing. This means you may not hear any noise, but the cavitation function could still be working properly. RF Heating Sensation Varies by Individual The RF (radio frequency) function gradually warms up the skin, but some users may take longer to feel the warmth. To ensure effectiveness: Make sure your skin is clean and free from oils or skincare products that might block energy transfer. Apply a sufficient amount of gel or serum to enhance conductivity. Keep the device in full contact with your skin and move it slowly for optimal heating. Check Your Settings Ensure the device is turned on properly and set to the desired mode and intensity. Try increasing the energy level to see if you can feel warmth or a slight pulsing sensation. Troubleshooting Make sure the device is fully charged or properly connected to power. Try testing on a different area, such as your arms or thighs, to check if the device is working. If you have tried these steps and still experience no effect, please contact Freyara customer support for further assistance.

1. Fuse protection A fuse is installed inside the Fuse knob, which is mainly used to protect the machine circuit. If the machine has an overload, short circuit or abnormal voltage, the fuse will automatically blow to prevent machine damage or safety accidents. 2. How to use the Fuse knob Under normal circumstances, there is no need to twist or replace it. If the machine suddenly fails to start or loses power, it may be that the fuse is blown. You can unscrew the Fuse knob, take out the fuse and check whether it is burnt out. Replacement method: Take out the damaged fuse and replace it with a new fuse of the same specification (usually the machine manual will provide the specification requirements of the fuse). 3. Maintenance of the fuse knob Avoid rotating the fuse knob at will when the power is on to avoid affecting the operation of the equipment. Check the power line regularly to ensure stable voltage and reduce the risk of fuse blowing.
