4.2.9 Load Optimized Defaults
NOTE: Load Optimized Defaults loads the default system values directly 
from ROM. If the stored record created by the Setup program should ever 
become corrupted (and therefore unusable), these defaults will load auto-
matically when the ARK-339X Series system is turned on.
