ABSTRACT:
A remote control device for off-the-shelf stereo audio systems in which an R.F. receiver unit controls the functions of the stereo system through electric motors mounted upon the control shafts of the stereo receiver. The motor controlling the tuning function of the stereo receiver is switched off whenever a stereo station is reached during tuning by a photosensor attached over the stereo indicator light of the stereo receiver. Continuous operation of the motor controlling the tuning of the stereo receiver to bypass undesired stereo stations is achieved by overriding the signal from the photosensor. Each of the R.F. receiver unit and transmitter unit has a plurality of plug-in modules with each module having its own tuned circuit and dip switch, so that each module can be used for a separate control function. A digital controlled oscillator in the transmitter unit excites each transmitter module. The plug-in modules are easily inserted or removed to allow for easy replacement and for additional functional capabilities of the remote control system.
