Abstract of the Disclosure A portable radio communication device comprises a battery, a DC-DC converter for stepping up the battery voltage and a processing circuit for detecting and processing received signals. The processing circuit has a presetting terminal and a power supply terminal to which the stepped-up voltage is applied. A presetting circuit is connected between the output of the DC converter and the presetting terminal and is arranged to set the processing circuit in its initial state in response to the stepped- up voltage. A power supply switch has a first terminal connected to the battery, a second terminal connected to a reference potential point and a third terminal connected to the input of the presetting circuit either directly or through a low value impedance. In the "ON" position of the power supply switch the first and second terminals are connected together thereby supplying the battery voltage to the communication device and in the "OFF" switch position the second and third terminals are connected together cutting off the battery voltage. Additionally and unique to the invention, the provision of a conductive interconnection between the third terminal and the presetting circuit has the effect of reducing the discharge time of the presetting circuit when the switch is switched to the "OFF" position. This is an improvement over conventional such devices in which the presetting circuit would not have sufficient time to discharge if the switch were turned "OFF" and then "ON" again after a short period of time, the result being that the pro- cessing circuit cannot be set in its initial value.
