input of hexadecimal values, it is also necessary to create numeric keys A through
F.
With the NT20S, if the numeral setting attribute is set to “system”, apart from the
numeric keys prepared by the system, the touch switches allocated to system
keys ( , , ) have to be created. (“System key functions”, page 139)
