Minor graphical user interface modifications (e.g., replacing the word "EXIT" with an arrow icon).

In order to perform the update, please proceed as follows:
- Connect a storage device containing the firmware file (if the file is compressed in a .zip archive, it must be extracted and the file with a .bin extension copied to the storage device).
- Access the main menu.
- Navigate to the "System" window (indicated by a "gear" icon) using the left/right arrow buttons.
- Select Software Update -> USB Update.
- Highlight the "Section" item and change the setting to "All" using the left/right arrow buttons.
- Navigate to the "File Path" option, select the firmware file, and confirm the software installation process.
Upon completion of the update, the receiver will automatically reboot and display the initial installation screen.
