Abstract
A remote control device including a receiver for receiving a control signal which remotely controls an external device, a RAM for storing the received control signal in correspondence to a respective one of keys, a transmitter for reading a control signal corresponding to an operated key from the RAM and transmitting the read control signal, and a display for displaying the stored data in the RAM when the control signal is received/transmitted. In a first aspect, when an external control signal is received and stored for any key, a key for which no control signal is stored is detected from the RAM and displayed on the display. When a control signal is transmitted, a key for which a control signal is stored in the RAM is detected and displayed on the display. In a second aspect, when an external control signal is received, a detector detects the contents of the received control signal, which are then displayed on the display. By such arrangement, when a control signal is transmitted/received, the user can easily know a key to be operated and whether the external control signal has been received correctly.
