What to do if TX icon appears on Yaesu FTA-750 Spirit display?
If the 'TX' icon appears and the radio is inoperable when connecting the SCU-15 headset adapter cable, it's likely that the plug isn't fully inserted into the MIC/SP jack. Ensure the plug is completely pushed into the MIC/SP jack and secured with the two screws.
