• Streamlined Firmware Updates: The software alerts you when updates are available, letting you easily update individual modules and review release notes for peak performance.
• Custom Machine Configuration: Easily modify and program operational parameters—like battery types, charger locations, drive options, and dust control systems—using simple drop-down menus.
