Which command must be sent to display RS parameters on the EPLRS?

To display RS parameters on the Enhanced Position Location Reporting System (EPLRS), the command that must be sent is to enter a specific designation in the MSG field. This action activates the system's function to fetch and present the relevant RS parameters.

Entering a command directly into the MSG field, such as the blank entry indicated, allows for a simplified approach to accessing specific functions within the system, such as displaying parameters related to RS configurations. This direct interface is an essential part of user interaction with the EPLRS.

Other choices do not effectively navigate the system to display the RS parameters. Simply pressing the OK button or typing out commands that do not directly correspond to the system's operational commands may not yield the desired results. Loading RS configuration pertains to settings changes rather than the display function and would not provide the parameters directly upon input.
