How does it work?
1. Press and hold for 2 seconds to turn on/off
2. Mode switching with a single press:
a. Fast mode (blue light)
b. Slow mode (purple light)
c. Interactive mode (yellow light)
3. After 5 minutes in each mode, it enters standby mode; if not woken up within 30 minutes in standby mode, it will automatically shut down. The indicator light flashes twice every minute in standby mode.
4. Low voltage indicator: the red light flashes rapidly before turning off
5. While charging, the red light flashes, and when fully charged, the red light stays on
