What action is required when the site controller enters diagnostic mode?

When the site controller enters diagnostic mode, the primary action required is to run a diagnostics check. This mode is specifically designed to facilitate troubleshooting and maintenance tasks, allowing technicians to assess the health and functionality of the system. By running the diagnostics check, the technician can pinpoint issues, evaluate performance metrics, and determine if any components need attention or repair.

This process is vital for ensuring the system operates efficiently and reliably, as it provides critical insights into potential problems that may not be immediately visible during normal operation. Engaging in diagnostics checks in this mode is a standard procedure to verify that all system components are functioning as intended.
