Function description

Shutdown status: power off and does not work. Press the power key to start the machine.

Power on status: the buzzer will give a long sound (0.5 seconds) during power on, and then enter the mode used before power off. Press the power button and the buzzer will beep twice before turning off. During operation, the display screen displays the current mode, gear, current current, remaining working time and dynamic effect

Gear switching: press the upshift key once to increase the gear by one, and press the downshift key once to decrease the gear by one.

Mode selection: select the import mode, export mode, RF red light mode, ice blue light mode and pull mode through the mode key cycle.

Import mode: import is displayed, and the working time is 5 minutes. The introduction function works, and the vibration motor works.

Export mode: export is displayed, and the working time is 5 minutes. The export function works, and the vibration motor works.

RF red light mode: display RF led, working timing 6 minutes. RF function works, red light function works, vibration motor gap works.

Ice pack blue light mode: Cool LED is displayed, and the working time is 3 minutes. The refrigeration plate works, the blue light function works, and the vibration motor gap works.

Lifting mode: smoothing is displayed, and the working time is 5 minutes. EMS lifting function works and vibration motor works.

Charging indicator: insert the charger, enter the charging state, and all functions are turned off. The display only displays the battery power, and changes gradually from the current power to the full grid. After full charge, the battery indicator is on for a long time.

Low voltage shutdown: if the battery power is 0 grid and the battery voltage is less than 3.2V, the buzzer will shut down twice.

Timed shutdown: after the working time of the current mode is over, the buzzer will shut down twice.
