Operational Guide

1. Check if the USB driver is successfully installed and running properly

Go to the computer device manager, click the port, and right-click Properties to check whether the driver is successfully installed and running normally.                                    
                                                                                                                                                                     

2. Check if the USB cable is damaged

Use a multimeter, switch the gear to the on/off position, touch the red test lead to the A terminal, and the black test lead to the B terminal, and look at the display of the multimeter to determine whether the USB cable is connected or disconnected.                                                                                                                                                                                                                                                                                                                                                                                         

  Not connected                                     Connected (the value on the multimeter will change and there will be a beep)

3. Check whether the USB port of the motherboard is abnormal

  1. Use an M2 hexagonal wrench to remove the right door of the device.                                                                                                                                                                                                                                                                                                                                    
  2. Find the motherboard and unplug the USB cable that was originally inserted                                                                                                                                                    
  3. Directly plug in the USB cable provided with the device                                                                                                                                                                                                                                                                                                                                                          
    •  If the device can be connected and used normally, the USB extension cable from the internal board of the device to the external USB interface is damaged.Please contact the manufacturer for replacement.
