Which statement about HMI is true?

Explanation:
The main idea is that the HMI acts as the centralized interface an operator uses to control DMR operations. It provides a single point of control, letting you manage what talkgroup or channel you’re on, monitor status, and issue routine commands from one place rather than juggling multiple devices. That centralized control is what makes this statement true. Encryption is handled by the radio or crypto modules, not by the HMI. Power supply management is separate hardware, not a function of the interface. A repeater is an independent piece of infrastructure that extends coverage, not something the HMI performs.
