Execution of guide simulation of the button operation is accompanied with the display of the button operation procedure and also the indication of the fact that a key telephone is actually used or a tone is being generated. The simulation state is first set by the button operation in one of many key telephone sets (1-1 to 1-m), and first control information is produced. A main control unit 10 sets an initial state of simulation in accordance with the first control information at a particular key telephone set which outputs the first control information. Second control information is then supplied to a main control unit 10 by pushing the operation button of the key telephone set, and display of the button operation procedure and indication of a lamp or generation of the tone, which are similarly created as a function is actually executed, are carried out in the key telephone set under control of the main control unit 10. In other words, a user can easily master the button operation by falsely creating the state where the key telephone system is being used. |
