COMBAT VEHICLE CREWMAN (CVC) HEADSET COMPONENTS REMOVAL AND

REPLACEMENT PROCEDURES

There are two designs of CVC headset (See Figure 3-10). The newer design, commonly

referred to as "Product Improved" CVC (PICVC), has a one-piece microphone, boom,

and cable assembly which is interchangeable with the earlier design CVC. Additionally,

the PICVC has talk thru circuit (TTC) capability powered by either a rechargeable or AA

alkaline battery located in a compartment situated on the left earcup. The new PICVC

utilizes two liners (large, medium) instead of the three liners (large, medium, small) used

the previous model CVC. All the liners are interchangeable with regards to the earcups

and cable assembly fitting into them. The pads installed in the PICVC liner have been

improved and can be removed and replaced. These pads, which come in large and

medium kit sizes, are interchangeable with the pads in the earlier design CVC liner. The

set of large pads is installed in both large liners. The set of medium pads is installed in

both medium liners as well as the CVC small liner.
