Abstract
In a remote controller, a startup time or a first time duration until the startup time is input into an input unit. A timer unit counts a clock time or a second time duration. A control unit generates a signal to turn on an electrical apparatus when the second time duration reaches the first time duration, or when the clock time equals to the startup time. A transmitting unit transmits the signal. In the electrical apparatus, a main unit operates main function. A transformer supplies electricity from an external power source to the main unit through a switch. A rectifier rectifies the signal. A signal identifying unit identifies it. A reservation memory unit keeps parameter for main function. A control unit turns on the switch and controls the main unit according to the parameter when the signal is received. A battery supplies electricity to above units.
