What to do if the 'TX' icon appears on Yaesu FTA-450L when connecting a headset?

If the 'TX' icon appears on the display and the Yaesu Transceiver cannot be operated when connecting the SCU-15 headset adapter cable, this indicates that the plug on the SCU-15 headset adapter cable is not properly inserted into the MIC/SP jack. To resolve this, ensure the plug is fully pushed into the MIC/SP jack and secured with the two screws to establish proper contact within the radio.
