When you use a new microSD card for the first time, always format it through the Camera System Configuration Menu or the Sena Camera App before using the camera system. Formatting the microSD card will remove all files from the card. If you are formatting a microSD card that you have used before, back up anything you want to save before formatting.
Tap the Center Button when in this menu to remove all files from a microSD card. When you use a new card for the first time, always format it before using the camera system.
