To reformat the microSD card on a ContourROAM, open the back door of the camera.
Now using a small pin or the end of a paperclip, press and hold the button inside the Format hole located beneath the microSD card slot.
Press and hold that button until the camera beeps once and/or the card light on the top of the camera stops flashing and turns solid green.
The microSD card is now empty and properly formatted.
Warning: Formatting the microSD card will erase all data on the card.
