摘要： A key telephone system includes a terminal and a primary device. The primary device transmits a command for transition into a power-saving state to the terminal, together with a power-saving duration time datum and/or a power-saving deactivating time datum, when the time reaches a power-saving state transition time. The terminal specifies the power-saving duration time and/or the power-saving deactivating time in the timekeeper means, and halts the communication means for communicating with the primary device at the time of receiving the command for transition into the power-saving state from the primary device, and activates the communication means being halted at a time when the timekeeper means has measured the lapse of the power-saving duration time and/or the power-saving deactivating time.
