Overview This function works only with Compact controllers. This function cannot be
performed while the controller is running. You must stop the controller first.
Tip: Memory Protect is a switch on your controller that stops you from altering the
controller’s contents. The Memory Protect switch should be ON or the card
overwrites memory on power up.
