These keys instruct the FM/AM-1200S/A processor to perform a specific
operation or function to permit the execution of a key entry. Specific
key functions are as follows:
2ND FUNCT Key - Conditions the FM/AM-1200S/A processor for a 2nd order
function entry; this key must precede the 2nd function

FM/AM-1200S/A. All Keyboard entries are immediately
displayed on the VFD but will not be executed by the
