In order to insert an SD Card into your camera, you must locate the small rubber/plastic hatch that will give you access to the SD card slot. It's usually located close to the blinking LED light, but its position may change depending on the model.

Once you've located it, simply open the hatch, insert the card and close the hatch again.

If you wish to reset your camera, you must first locate the reset button. You will usually find it beneath the same hatch you need to open when adding an SD Card.
