A method of controlling an electronic apparatus includes supplying power to a second controller, receiving an activation time for supplying power to a communication portion and a deactivation time for interrupting power to the communication portion, setting time information based on the activation time and the deactivation time, performing, based on the time information, a standby step that includes interrupting power to a first controller, a first load portion, and the communication portion while supplying power to the second controller, controlling the communication portion switch to supply power to the communication portion based on the activation time, determining whether the communication portion has received the control command from the remote control terminal, and interrupting the power supplied to the communication portion and re-executing the standby step based on determining that the communication portion has not received the control command from the remote control terminal.
