Inserting the Batteries and a Memory Card
• Formatting a memory card in the camera creates a folder in which pictures are
stored. Do not rename or delete this folder or use a computer or other device to
edit, delete, or rename image files. Always use the camera to delete pictures; before
editing or renaming files, copy them to a computer and edit or rename the copies,
not the originals.
