The purpose of the red BUSY LED is to inform you that the camera is working and performing an action.
The busy light will turn ON when the camera is:
- powering ON.
- taking a photo.
- recording a video.
- transmitting photos. The busy light may stay on for several minutes while transmitting.
- performing a firmware update. The busy light will blink slowly at the beginning, then it will blink faster at the end of the firmware update. When the update is complete, the BUSY light will turn OFF and the camera will take a restart.
