PROBLEM TO BE SOLVED: To provide a remote control device with interphone function, capable of improving power saving by reducing a current consumption.SOLUTION: When a kitchen remote control 2a becomes a transmittable state by the operations of call switches 271, 371, a power circuit 26 is blocked and switched to stop current supply to a receiver 25. When voice signal detection in a transmitter 23 by a voice signal detector 211 has not been performed, current supply to a microphone amplifier 232 of the transmitter 23 is stopped. At this time, a bathroom remote control 3a becomes a receivable state, a power circuit 34 is blocked and switched to stop current supply to the transmitter 33. When voice signal detection in the receiver 35 by a voice signal detector 311 has not been detected, current supply to a speaker amplifier 352 of a receiver 35 also is stopped. |
