Three-color mixed, with lamp charging fan, brushless motor drive, 199 speed battery uses 21700 3000MAH lithium battery. Always press the power switch to turn on the machine. When the fan is working at gear 1, the 4 LED lights on the power switch will be triggered to brightness at gear 1, and then the 4 LED lights on the power switch will be triggered to brightness at gear 2 (brighter). Then the power switch will be triggered, and the 4 lights will flash. Then, the 4 LED lights will go out. When the power supply is working at gear 1, the wind speed will gradually accelerate until gear 199, and the digital tube will simultaneously display the gear. Triggering the switch (+), the fan wind speed is at 50, then triggering the switch (+), the fan wind speed is at 100, then triggering the switch (+), the fan wind speed is at 150, then triggering the switch (+), the fan wind speed is at 1199, and the digital tube displays the corresponding wind speed gear, then triggering the switch 2 (+), the fan keeps working and does not respond. At this time, press and hold the switch (-), the wind speed gradually slows down until gear 1, and the digital tube simultaneously displays the gear position. If the switch (-) fan wind speed is triggered at 150, the switch (-) fan wind speed is triggered at 100, and then the switch (-) fan wind speed is triggered at 50, and then the switch (-) fan wind speed is triggered at 10, and the switch (-) fan wind speed is triggered at 10, and the digital tube displays the corresponding wind speed gear. Then the switch 3 (-) fan remains working without any response. After the fan works for about 5 seconds, the digital tube automatically jumps to the battery level display. When charging, the digital tube has a battery level display, and the % sign on the digital tube flashes
