A programmable remote control transmitter has a programming mode and a controlling mode and is used to control electric devices such as television sets. The remote control transmitter has a memory for storing a limited number of remote control codes. There is a keypad for selecting one of the stored codes and a transmitter for transmitting the remote control signal corresponding to the selected remote control code to the electric device such as a television set. Remote control codes are able to be input to the memory of the remote control transmitter only when the remote control transmitter is in programming mode. In normal operation the remote control transmitter is in controlling mode. A removable key must be used to change the mode of the remote control transmitter from controlling mode to programming mode. |
