I don't understand the question.

If you are talking about reviewing the photos you have taken.
You just press the left or right button to go through the photos one at a time.
If you hold down the button, it goes through the images quickly so that you can skip forward.
That skip speed is not adjustable.
See page 18 of the Camera User Manual (Basic).

If you want to review the images like a slide show, that is discussed on pages 93 through 97 in the Camera User Manual (Advanced).
The adjustment of the review time is discussed on page 97.
