Patent ID: 8327160

Claim:
A remote controller for controlling an electrical apparatus to turn on at a startup time comprising: an input unit into which the startup time or a first time duration until the startup time is input; a timer unit which counts either a clock time or a second time duration; a control unit which generates a first signal to turn on the electrical apparatus when the second time duration counted by the timer unit reaches the first time duration, or when the clock time counted by the timer unit equals to the startup time; a transmitting unit which transmits the first signal to the electrical apparatus; and a receiving unit which receives a second signal from the electrical apparatus indicating a third time duration until the startup time; wherein the transmitting unit transmits a third signal indicating the startup time to the electrical apparatus; the receiving unit receives the second signal after transmitting the third signal; and the control unit generates the first signal by using the third time duration instead of the first time duration when the receiving unit receives the second signal.
