Only place all files under the root directory. Don't put them in any sub-folder.

Power off the machine and insert the USB drive into the machine's USB port. Then turn on the machine again.

NOTE

Please use USB 2.0 Drives with capacity under (includes) 16GB.

After power on:

  1. Firmware update

The touch screen will not light up during the update process. During the process you can hear the buzzer tone sounding like: Di-Di-Di-Di-Di-Di~Di-Di.
