At this time, the power button can be released and the electric pump enters the working state. When the power button is turned on for 3 seconds while the electric pump is turned on, the LCD screen lights up and the message “Shutdown” is displayed. At this time, the power button can be released, and the electric pump automatically turns off after counting down to 1.
(2) Function selection: There are three modes of motor operation of electric pump <25Oml/min>, <500ml/min>,<air pump stop>. When the power is turned on, the electric pump automatically enters the working mode of 250ml/min, and the motor starts to work. If the function selection button is pressed, it can be switched to the working mode of 5ooml/min. Press the function selection button again to switch to the air pump stop state, and
the motor stops working. During the mode switching process, the LCD screen has corresponding prompt information.
(3) Charging: Plug the corresponding USB cable into the USB charging port. If it is in the off state at this time, the screen will display “Charging”, if the charging completion screen displays “Charging Complete”. The percentage of charging process is displayed during charging. This percentage is based on the battery voltage and is for reference only. Since the performance is attenuated after the battery is charged and discharged for a long time, it is normal to display the charging percentage at a high speed.
