Flash ROM Updates
The NR-500 Series register software is loaded in flash ROM. 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 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.
