Abstract
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.
Claims6
A programmable remote control transmitter having a programming mode and a controlling mode for controlling an electrical device, said transmitter comprising
- memory means for storing a predetermined maximum number of remote control codes,
- a keypad for selecting one of the stored remote control codes when the remote control transmitter is in said controlling mode, with the keypad operatively connected to a transmitting device for transmitting remote control signals corresponding to the selected remote control code to said electrical device,
- keypad keys for controlling the on and off functions of said electric device,
- means for inputting remote control codes to said memory means only when the remote control transmitter is in said programming mode, and
- means for selectively permitting the remote control transmitter to be placed in said programming mode comprising a locking mechanism integral with the programmable remote control transmitter and a removable key,
- wherein said keypad key controlling the on function is operatively connected to said transmitting device for transmitting remote control signals such that immediately following the transmission of the remote control signal to turn, on the electrical device a second remote control signal is transmitted corresponding to a specified one of the remote control codes stored in said memory means.
