If your headset is shipped with the microphone assembly packed separately, you can attach it to either earcup. Attaching the microphone assembly Choose the earcup (L or R) to receive the microphone assembly. Also, make sure that the earcup connector pins are clean and free of debris. 1. Use a Phillips screwdriver to loosen the two screws on the access cover near the bottom of the earcup where you want to attach the microphone assembly. 2. Remove the access cover to reveal the connector pins on the earcup. 3. Carefully line up the microphone assembly to the small connector socket on the earcup. 4. Slide the connector into the socket until it reaches the stop. L for left Access cover Connector pins Microphone assembly Connector pins CAUTION: Do not force the connector into the socket, or earcup damage may occur. 5. Tighten the screws to secure the assembly. 6. Attach the access cover to the earcup that does not have the microphone assembly attached. Insert the screws, then align and tighten them. Note: The headset will not work without the access cover installed. CAUTION: Be sure to try the headset and fully test its operation before flight. 8
