## During Boot-Up

During boot-up, the camera will perform a **self-check** to guarantee proper functionality. During this check, the status and activity LED will show the following:

| **Status LED**   | Activity LED                                                                                 |
| ---------------- | -------------------------------------------------------------------------------------------- |
| **Constant RED** | <p><strong>Flashing RED</strong> <br>indicates an activation of</p><p>the camera trigger</p> |

For more details on the self-check, please refer to section [Powering ON the Camera](/hardware-and-interfaces/camera/a6k-lite-camera/powering-on-the-camera.md).

## During Operation (after self-check)

Based on the outcome of the self-check, the LED status will be the following:

| Status LED                                                                                                                                                                                                                               | Activity LED                                                                        |
