Flash Memory
Up to 96 images can be stored in memory. Flash memory does not require electrical power to store data,
so image data is retained in memory even when you turn camera power off.
If batteries go dead, simply load a set of new batteries or connect the AC adaptor and you will be able to
view images in camera memory.
