PROBLEM TO BE SOLVED: To provide a remote control transmitter remotely controlling a motor- driven opening/closing door that a user can easily confirm transmission of an opening/closing control signal even when a worn battery state is displayed. SOLUTION: The remote control transmitter 2 is provided with a transmission display light 5 and a voltage detection section 8. When a battery 7 is worn and the voltage decreases to a prescribed voltage V1 or below, the worn battery state is displayed after transmission indication is made by the transmission display light 5 in the case of transmitting the opening/closing control signal S. |
