This is a professional-grade HIFU Liposonix machine commonly used in salons. It comes with 0.8cm and 1.3cm cartridges. Both have been tested and confirmed to be working. The number 576 written in the 6th image indicates that 576 points are continuously irradiated in a single shot (it is not the remaining number of shots on the cartridge). The remaining shots on the cartridges are: 0.8cm → 463 shots (approximately 87% remaining) 1.3cm → 395 shots (approximately 74% remaining) It has a high output of up to 75J. The red exclamation mark indicates that it is a high-output machine, so please be careful. It is not a malfunction. Please connect the wiring as shown in the images. Turning on the power button on the back will display the 7th image, so press Exit. Then, the 1st image will be displayed. Press Ready, and then press the top button on the handheld irradiation device, which has two buttons. This will allow you to irradiate. Please feel free to ask if you have any questions.
