Read pages 13-15 in manual/ info,..then experiment
The multitude of settings is confusing,... Practice getting in and out of menu and settings
And there is a preferred sequence of setting mike and noise level. Unfortunately i do not recall what is preferred.
Recommend first trying to set mike level,....notice bar,.. When talking
Then,.. Engine running,..more than idle,..set noise cancel,... START WITH RECOMMENDED Vogad Med.. Then adjust as necessary in that range,.. Might need to use another range,...but doubt
Read and heed the note/warning in second paragraph on vogad,....wrong mic setting will allow noise
Radio can be very sensitive to mic position,.. During setting and operation,..keep it close
Keep trying,... Write it down when you get it right
