More Information
Summary:An electronic circuit device having an electric-code locking functions so that when the electronic circuit device is electrically connected to a battery, a control circuit is activated to cause a power supply detecting circuit to detect whether the electronic circuit device has been stolen. When a proper code is input by a control input unit after the completion of its detection, the electronic circuit device can be normally operated. In response to another simple operation signal input from the control input unit, the control circuit controls a radio receiving circuit, a tape circuit and a muting circuit in such a manner that the electronic circuit device is temporarily brought to the normal operation state. That is, the electronic circuit device can be provided with an additional function for temporarily bringing the electronic circuit device to an operation state by inputting an operation signal other than a signal indicative of a mnemonic in order to improve the efficiency of its fabrication.
