The numbered translucent covers on the input and output pushbuttons can be
removed and replaced to insert labels behind the covers.
Input and output labels can be created easily with Extron’s Button-Label Generator
software, which ships with every Extron matrix switcher. Each input and output
can be labeled with names, alphanumeric characters, or even color bitmaps for
easy and intuitive input and output selection (fi gure 3-2). See chapter 5, Matrix
Software, for details on using the labeling software. See Appendix B, Specifi cations,
Part Numbers, and Accessories, for blank labels and a procedure for removing and
replacing the translucent covers.
