Button Labels
Page B-9 provides strips of blank button labels. If desired, copy them or cut them 
out, write button information in each button area as desired, and put them in the 
switcher’s input or output buttons’ windows. You can also create labels using the 
Button-Label Generator software (see chapter 5, “Matrix Software”).
