SOLUTION: When the correspondence relation between an arbitrary parameter and a number is changed in a current parameter number area in a RAM 3 by the operation of a switch group 5, a CPU 1 corrects automatically a correspondence relation stored in a registration area in the RAM 3 according to the change.
