Menu Map

The NanoVNA-F V3 organizes all functions into eight top-level menus, accessed by tapping the right-hand touch area or pressing the middle button. Each menu branches into submenus up to three levels deep.

Tip

Tap <BACK in any submenu to return one level up. Tapping the graph area closes the menu entirely.
