PURPOSE:To make a remote control transmitter for service unnecessary and to exclude a factor to be an erroneous operation on a software operation in a microcomputer by providing an auxiliary switch in a remote control code data circuit and adding software to change processing contents even to the same remote control code by the ON/OFF of the auxiliary switch. CONSTITUTION:An auxiliary switch 2 switches DC voltage in the state of ON/ OFF. A signal is always searched at remote control input, when it is judged to be OFF, the original function of a remote control code is executed and when it is judged to be ON, the function different from a remote control code main body, the function programmed in a microcomputer 3 in advance for service or demonstration, for instance, is executed. Thus, a remote control hand set to realize the function for the service or for the demonstration is unnecessary and an erroneous operation to rush into a mode for the service or for the demonstration erroneously can be avoided. |
