REPARING THE

The microphone assembly

Your headset may be shipped with the microphone assembly (boom microphone
and cable) attached to the left earcup. 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.

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.
