Instructions for repairing a bad ground contact in the Auxiliary Audio Jack.

Models Covered:

A100T (all cord sets)
A100 (all cord sets)

Tools Required:

3/32 Hex head wrench
Small flathead screwdriver or Tweezers


Nearly every model of UFlyMike has come with an Auxiliary Audio Jack. This jack can be used for both input of audio from an external source, or for a secondary output of audio in parallel with the headphone. The contacts in the jack, namely the ground, can lose it's spring over time and no longer make good contact.


Please read and understand all instructions before beginning repair.

1. Using the 3/32 Hex head wrench, remove the three screws holding the cover on. Do not remove the cover.


2. While holding down on both the microphone boom and cord set near the housing, pull upwards on the cover. The cover should lift off with very little effort. Holding down on the microphone and cord will keep those components in the main part of the housing.

3. The ground contact is the metal strip on the Auxiliary Jack nearest the opening of the jack and on the side with the cord. The actual contact is the middle 2/3 that is inset.

4. The adjustment requires bending the small metal tab in towards the center of the jack. This is accomplished by placing the tip of the small screwdriver or tweezers on the tab and gently pressing inward. Once you feel it move that is usually enough. As a reference, you can see the tab inside the jack when looking in the plug opening. As long as it is protruding inside the jack, it is usually enough to make contact.

You must be very careful, if the tab is pushed too hard, it may bend all the way inside the jack and is hard to impossible to fix. This adjustment is best done slowly and carefully.


5. Check that all of the wires are clear of the pinch points between the main housing and the cover.

6. Place the cover back down on the main housing. When the cover is down flush with the main housing, the cord strain relief, microphone boom, and switch will hold it in place. Replace the screws and start each one, but do not tighten any yet. You may have to wiggle the cover a little to get the screws to thread properly. Once all three screws are started properly, tighten them until snug. Be careful, the housing is aluminum and can strip out if too much pressure is applied.
