# Powering ON the Camera - Self-Check The A6K-Lite camera will power on automatically when the entire system (NavBox) is connected to a power supply (make sure the LiDAR/Camera cable is connected between NavBox and camera). At boot-up, the camera will perform a **self-check** to guarantee proper functionality. During the self-check, the Status LED of the camera will be constant RED and the camera will trigger a total of 2 times (the Activity LED will signal a trigger event by flashing RED). After a successful self-check, the Status LED will turn to constant GREEN. Otherwise, if the self-check failed, the Status LED will start flashing RED. If this happens, the camera will not be operational. Please refer to section [Troubleshooting](https://docs.phoenixlidar.com/hardware-and-interfaces/camera/a6k-lite-camera/troubleshooting) of this manual. Once the Status LED is GREEN, the camera is ready for operation and can be used via Spatial Explorer.
