D User constants A1-01 through A1-03 and A2-01 through A2-32 can be displayed but not changed if
the contents of A1-04 and A1-05 are not the same.

sired values in A1-01 through A1-03 and A2-01 through A2-32. User constant A1-05 can be displayed
by displaying A1-04 and pressing the Menu Key while pressing the Reset Key. (A1-05 can’t be dis-
played with the usual Key sequences.)

ten to A1-04 and A1-05.
