Microphone Not Working Through Auxiliary Jack
The Microphone can only be connected to one destination at a time. Either it is connected to the Aircraft or to the External Device connected via the Auxiliary Jack.
1) Set the Aircraft/Phone switch (located on top of the Aviation Controller) into the 'Phone' position.
2) Clean the plugs of the Auxiliary Cable by wiping them with a soft cloth.
3) Test the headphones separately from the HARMONY to verify that they are functioning properly.
4) Try a different Auxiliary Cord (our Aux Cords are standard four conductor cables found at most electronics retailers).
