When repairing any headset component, care should be taken to identify cables during disassembly to facilitate
proper reassembly. All cables are colored coordinated (I.E. Red to Red, Blue/White to Blue/White, Green to
Green, etc). All cable and switch entries should be resealed after assembly with any standard commercially
available silicone sealant to preserve waterproofing and the sound attenuation, which protects hearing and aid
in intelligible communications. When repairing the Talk Circuit, remove the foam inserts and earphone from the
right earcup. Take note of the order of assembly for replacement. Unplug the Printed Circuit Board from the
three mini-connectors. Replace the Printed Circuit Board and test the talk circuit. If fault persists, remove the
screen and washer from the outside front of the earcup with a small screwdriver. Push the Microphone into the
earcup. Remove the silicone sealant from the inside of the earcup and replace the microphone from the inside.
Seal the microphone in place with silicone sealant. Use a small amount of sealant around the edge of the new
screen assembly packaged with the Microphone and press into place on the outside of the earcup. Re-
assemble earcup.
