When you look at the help I posted, when you open a rasters properties in the TOC and go to the display tab, if your raster has rational polynomial coefficients (RPCs) a box that says orthorectification using elevation can be checked. That box will be in the bottom right corner of the screen under Orthorectification is the one you saw in the screenshot I do believe, or a similar version(I'm on 10.1 so can't check for sure.)
