You can Click Here for the camera manual. Since this camera is new to you. I would reset the camera to factory along with all of the custom functions. Also note this is an older camera. This camera DOES NOT use regular SD cards. This camera uses CF cards (Compact Flash). Most high-end and professional grade cameras use this type of memory card. I would buy 2 of them to use with your camera. Since this is an older camera I suggest you get 8GB cards. Larger CF cards may not be compatible with your camera.
