Mode selection and LED light behavior check
Potential Causes
- A mode has not been selected after powering on.
- Different modes activate different LED lights.
- Not all LED lights turn on at the same time.
- infrared light is not visible to the human eye.
- Some LED beads may be blocked, damaged, or not lighting normally.
- The device may need further inspection.
Troubleshooting Steps
- Select a mode after powering on
After turning on the device, press the mode button to select a treatment mode. - Check different modes
Switch between modes and observe whether the visible LED lights change. - Understand normal LED behavior
Different modes activate different light combinations, so the number and color of visible LED lights may vary by mode. Not all LED lights will turn on at the same time. - Note that infrared light is invisible
Some modes include infrared light, which is not visible to the human eye. If you cannot see this light, it does not necessarily mean the LED is not working. - Check for visible damage
Check whether any LED bead is visibly damaged, burned, blackened, or physically broken. - Record the mode switching process
If the issue continues, record a short video showing the lights while switching between modes.
