Abstract

A power-saving control apparatus includes a memory storing first to Nth different authentication codes, determines, every time a signal including an authentication code is received, whether the authentication code in the received signal is a valid code which matches one of the authentication codes in the memory, outputs an operation signal to a main apparatus when the authentication code in the received signal is determined to be the valid code, and generates a new authentication code, when (a) the number of times the authentication code in each received signal matches a first authentication code of the authentication codes in the memory is equal to a predetermined value or (b) the authentication code in the received signal matches a second or subsequent authentication code of the authentication codes in the memory, to delete one of the authentication codes in the memory, and to store the new authentication code in the memory.
