Transferring Memory Contents to Controller EEPROM
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.
