The SD memory card, SDHC memory card, SDXC memory card or Eye-Fi cards have a write-protect tab.
If the <Write Protect Tab> is in the locked position, the following screen appears.
[Memory card locked] appears in the upper portion of the screen, and
[Recordable shots] or [Elapsed Time] shows *, shooting is not possible.
* The above indications
may not appear depending on the model of your camera.
If you try to delete an image and [Memory card locked] appears in the lower portion of the screen, the image cannot be deleted.
If [Memory card locked] appears on the [LCD Monitor] of the camera,
the <Write Protect Tab> of the memory card being used is in the
locked (downside) position, so you cannot capture or delete images.
To unlock the tab, slide
the <Write Protect Tab> of the memory card upward.
