Choosing the Latest Firmware file

  • If multiple versions are displayed, select the highest version number that matches your model (for example, 3.52R1 > 3.51R1).

  • If the numbers and letters are the same, select the highest numbered letter (for example, 3.52R2 > 3.52R1).

  • Verify the model reference to ensure compatibility.

Note: Never modify firmware filenames.
