A person's hand interacts with the touchscreen interface of a white machine, likely a device used in a beauty salon or medical setting. The hand, wearing a dark bracelet, taps the screen to adjust various settings. On the screen, there are several adjustable parameters: - "пульс" (pulse): The value is initially 10, then increased to 16, and finally to 20 by tapping the right arrow icon. - "частота" (frequency): The value starts at 1, then increased to 4, and subsequently to 5. - "власть" (power/strength/intensity): This setting is visible with a value of 5. The screen also displays a "← вернуть" (return) button at the top left, and icons for "play" (a triangle) and "stop" (a square) at the bottom. The hand presses the "stop" icon at the end of the clip. On the left side of the screen, an illustrative image shows a person's upper back and shoulder area. Additional small text at the bottom left indicates "22 C°" (22 degrees Celsius) and the number "2399". The background is a plain, light-colored wall. The location is provided as Budva, Montenegro, though this is not visually discernible from the video itself.
