Always wear the included safety glasses when using the beauty device. 1. Before using this product, shave the area to be treated. Then, thoroughly wash and dry the shaved area.

The light on the device will turn on and display "OFF." 3. Press and hold the power touch button for 2 seconds to start the device. Check the mode on the display before use. 4. Switch between modes depending on your intended use. Briefly press the touch button (left) on the display to adjust the level. For hair removal, make sure "HR" is displayed on the display. 5. The irradiation level can be adjusted in 9 levels. Briefly press the "+" touch button on the display to adjust the level. If using for the first time, be sure to start with "1" (the weakest level). After that, increase the level while observing the condition of your skin. The higher the level, the stronger the effect, but the greater the risk of skin irritation. Set the intensity to a comfortable level. 6. Irradiation Settings (1) Manual Irradiation Mode: When you turn on the device, it automatically switches to manual irradiation mode.
