What message indicates the operating system is installed but no application is running on the Commander?

The message that indicates the operating system is installed but no application is running on the Commander is the Watchdogmessage. This message is typically displayed when the system is operational, meaning that the fundamental software layers are up and running, but there is currently no application in execution to handle tasks or respond to user commands. The presence of the Watchdogmessage can serve as a diagnostic indicator for technicians, allowing them to understand that while the hardware and operating system are functioning, further action is needed to launch or troubleshoot the application layer.

Other messages, such as System OK, might suggest that the system is functioning normally, but they do not specifically indicate the absence of an application. Similarly, messages like Call HD WDT and Buypass are not designed to communicate this specific status regarding the application layer. Thus, the Watchdogmessage directly correlates to the scenario of having an operating system in place without an active application, highlighting its correctness in this context.
