Button icons
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 is shipped with every Extron matrix switcher. Each input and
output can be labeled with names, alphanumeric characters, or . color bitmaps for
easy and intuitive input and output selection (figure 3-3). See chapter 5, “Matrix
Software”, for details on using the labeling software. See appendix B, “Reference
Information”, for blank labels and a procedure for removing and replacing the
translucent covers.
