If the red transmit LED on your Vertex Standard Transceiver turns on and the radio becomes inoperable when connecting the CT-96 headset cable, ensure that the connector on the CT-96 headset cable is screwed into the MIC/EAR jack. Simply pushing the connector in is not sufficient to establish proper contact within the radio.
