What indicates the SCSR 100 is in good condition?

The correct indication that the SCSR 100 is in good condition is a green light. A green light typically signifies that the device is functioning properly and is ready for use, indicating that all systems are operational and there are no issues that need addressing.

In contrast, other indicators like yellow warnings and red signals usually signify caution or a malfunction. A yellow warning could indicate a potential problem or that maintenance may be required soon, while a red signal often means there is a critical fault or hazard that needs to be addressed immediately. The light blue indicator does not standardly represent the operational status of the device, making it an incorrect choice for assessing good condition. Thus, the green light serves as the clear and universally accepted signal of an SCSR 100's good working condition.
