[Elecraft] KX3 Questions on tuning with T-1,etc.

[Michael E. Califf,Sr]

I have new KX3, applied power, no apparent readings on S Meter. hissing noise heard but no signals.
ATU is on Auto
can’t figure out how to get T-1 to tune the radio.
can’t seem to get any readings on s-meter as to input. antenna works with other radios
I have MIC plugged in if that makes any difference.
Really confused and need help!!
