A: Removing or replacing the ProFlight cable assembly is quick and easy.  On the microphone connector at the headset, push the release button and gently pull the connector from the headset. Tip: You might need to rotate the side pad to access the connector.
This procedure also allows you to switch the boom from the left to the right side (or vice versa).
1. On the terminal cover at the other side of the headset, push the release button and gently pull the cover from the headset
2. Connect the terminal cover to the opposite side of the headset by aligning the release button on the cover to the button opening on the headset, then slide the cover into the headset Note: Do not force the cover. If you have difficulty, check that it is aligned properly. If it does not connect, the headset will not product sound.
