"To protect images on your memory card that you want to make sure you don't lose these images, maybe you're handing your camera over to another photographer and you want to make sure that they don't accidentally delete any of your images, or that you yourself don't delete any of your images, you'll want to use this protect function. And what I'm going to do is press the menu button to get to my protect option in the menus and, I'm going to use the main control dial to scroll over to the first playback menu, the first main playback menu have a blue icon with a triangle on the menu, pointing to the right to signify play, and a dot on the top right corner. And then I'm going to use the quick control dial to scroll through to rotate - I'm sorry - not rotate, to protect. Protect images is now highlighted with my blue rectangle. And to activate this function I'm going to press set. Okay, now set is, if I press set, there is a key icon at the top right, I'm sorry, the top left side of my LCD screen. It's a blue square with a white key in the middle. Now to protect an image all I need to do is press this set button in the middle of the quick control dial, and I can scroll through different images, and when I find one that I want to protect, I just press the set button. Now, to signify that the image is protected, the LCD screen adds another key icon, a white box with a white key in the middle of it, to the top of your screen, it looks like that. To unprotect an image you just press the same thing, press the set button again, and that white icon will go away. So I can set protection or take a protection away. I can scroll to another image, set protection or turn protection off, I can also zoom out to index mode and protect images that way. I want to protect all of these images so I'm going to do that. This image, I'm going to protect and unprotect. It's really up to you. There's lots of different ways to view your images and it's very easy and simple to unprotect and protect them."
