What does a heart icon indicate on the diagnostic panel?

A heart icon on the diagnostic panel typically signifies that the system is operating normally. This icon serves as a visual cue, reassuring users that the device is functioning as intended without any detected issues or failures. The heart symbol is often associated with a positive status or health check, indicating that everything is running smoothly. In contrast, other icons or alerts would represent different statuses such as failures or low power conditions, which are indicated by different symbols entirely. Therefore, the presence of the heart icon is important for users to quickly assess the operational status of their device.
