Troubleshooting

☆ The power supply was cut off or the USB flash memory was removed during operation.

- A complete reinstall is necessary. Perform the operation again from the beginning.

☆ The installation cannot be executed and an error message appears in the display.

Check the following:

✓ Is the USB flash memory inserted correctly?

✓ Is the USB connector free from dust or dirt?

✓ Is the USB flash memory or the upgrade data itself damaged in some way?

Try installing it again by using another USB flash memory.
