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. To repair the talk-through switch, remove the foam fillers and earphone
assembly from the right earcup-taking note of the assembly order. Unplug the mini connectors coming from the
switch to the cables and printed circuit board. Unscrew the hex nut from the outside of the earcup and slide the
switch out thru the inside of the earcup. Replace in reverse order and seal around switch with silicone on the
inside of the earcup.
