How do I get a little black box to show up in my window function of my graphing calculator?

I am putting in the range of my graph for exponential equations, and the question tells me to use these numbers: xmin= 5 xmax=5 xscl=1 ymin=-1 ymax=60 yscl=5 xres=1 My problem though is when I put these numbers in and hit graph, it tells me that there is a window range error.

My problem though is when I put these numbers in and hit graph, it tells me that there is a window range error. The example in the book shows a little black box in front of the 5 for xmin. What does that mean and how do I get my IT-83 plus calculator to do that? I don't have the instructions and the on-line manual wasn't of any help.
