To upgrade the IS20 firmware without requiring an internet connection, you have the option to utilize the
USB port and a Windows computer. Follow these steps to proceed:

bring up the 'Boot Loader' page on the IS20 screen. Simultaneously, a new window will

copy process to complete, which typically takes around 10 to 15 seconds.
5) Close the window that displays the drive.
6) Turn off the power and disconnect the USB cable from the IS20.
7) Restart the IS20, which will now operate with the new firmware. You can verify the firmware
version on the setup page.
