[Elecraft] KX3 Headphone set up problem

[Michael Heit]

I bought the Heil headphone set up with my KX3 but have never been able to get the mic to work right. I followed the instructions for installing it and the menu items needed but every time I plug in the mic plug the radio immediately goes into transmit mode.
The reason I wanted the headset was hands free operation, the earphones are great but I cannot use the mic installed? Has anyone else had this problem? Did you cure it? Hos so??
Thank you,73Mike AD7VV
