Format the memory card ( it can be formatted on the computer/machine).

Copy the upgrade file. Bin to the root directory of the storage card.

Insert the memory card with the upgrade file into the SD card slot ( note that the machine must not be turned on the parking monitor, and the machine must be in the shutdown state).

Connect the power, the machine starts to upgrade, and the LED on the left side of the machine flashes blue until the machine comes out the current boot screen (note that the upgrade process must not be powered off).

After power on, the memory card needs to be formatted to avoid upgrading again.
