Button Label Replacement
Different button designs are used on various Zodiak control surface panels.
The following buttons have a design which provides for label replacement:
•
Large buttons (used on Main and 24-Crosspoint Aux Panels), and
•
32-Crosspoint Aux Panel buttons.
A working button consists of a switch, an LED or lamp, and a removable
keycap. A keycap, in turn, can consist of a base, diffuser, film label, and
lens. The various button designs are similar, but their differences affect the
procedures used when changing button labels.
Note
Use care when removing keycaps from a control panel. The keycaps have
small parts inside that can fall out and possibly drop into inaccessible areas.
Note
To prevent scratching button parts, wrap plier jaws with tape before use.
