Which component is not part of the recommended assembly order for two-piece RADAR units?

The display is not considered part of the recommended assembly order for two-piece RADAR units. In the assembly process, the antenna and box are typically set up first as they are essential for establishing the basic functionality of the RADAR system. The "current" could refer to the power supply that aids in activating these components.

After the necessary foundational components are in place, the display is generally integrated last. This is because the display serves as the interface for interpreting data rather than being integral to the primary signal processing in the initial assembly phase. It is important to follow this order to ensure that all functional components are correctly aligned and operational before integrating visual output elements.
