Flash ROM Updates
The ER-230, ER-4xx and ER-52xx/M register software is loaded in a Flash ROM (erasable
programmable read only memory). This program may occasionally be updated by the manufacturer.
Your SAM4s dealer can update the software if necessary.
The Flash ROM can be loaded through a PC Utility or by SD card.
CAUTION: Flash ROM update by either method must be done by a qualified, trained technician.
DO NOT POWER OFF OR ABORT any program loading once it has started. Failure to
follow the procedures exactly may cause the program to load incompletely and for the
register to fail completely.
