Firmware Upgrade Process:

1. Connect the power cable to the D900 and the power outlet.

2. Use a USB cable to connect the D900's USB-B port to the computer's USB port. (Firmware upgrades are only supported via the USB-B port; the USB-C port is not supported)

3. Turn off the device with the power switch on the back. Press and hold the knob, then power on with the power switch. The screen will show the current software version.

4. A removable drive will show up in the explorer on PC/Mac. Open the drive.

5. Copy the .Topping file to the root directory of the drive. The drive will then eject itself and reconnect.

6. Reopen the drive. A new file will be showing the current firmware version as "Update successful(Version.Vx.xx)" of which the "XX" is the new firmware version that indicates the firmware is successfully upgraded.

7. Turn off and on the device again. The upgrade is complete.
