If you want to do a complete reset back to factory defaults so you can set up the Apex like it's a brand new unit, follow these steps:
- For a Apex Classic, do an Initialize All of the Apex using the classic web pages (Configuration->Misc Setup page-Initialize memory->Initialize All)
- or through the display module menu system (System->Init Memory->Init All)
If you only want to clear out the programming for a specific output, click the gear icon for that output in Fusion, set the Control Type to "Advanced", then erase any of the coding listed in the Configuration window.
