Using a Memory Card
• SD memory cards and SDHC memory cards have a

must then turn write protection off whenever you want 
to record to it, format it, or delete any of its images.
• If a memory card starts to behave abnormally during 
image playback, you can restore normal operation by 
reformatting it (page 157). However, it is recommended that you always take along 
multiple memory cards whenever using the camera far away from the home or

commercially available data delete software to completely delete the data on the 
memory card.

before discarding or transferring ownership of the camera.
