exposed part of the wire once around the end of the ground lug. Solder the wire. Bend the
ground lug flush with the inside surface of the helmet shell.
(2) Attaching the CEP interface harness (CEP900-I04) to earcups.
CAUTION
To avoid damage to the earcup shell, ensure that the pilot hole is
located properly as specified in step (a) below.
(a) Use an awl to make a pilot hole 7/16 inch below (as worn) the center of the
(b) Lay the earcup on a flat surface, and drill a 1/4-inch hole into the pilot hole. (See

(c) Carefully pull the part of the communications cord that extends into the right
earcup out from behind the energy-absorbing liner.
(d) Reinsert the communications cord with the grommet back into the previously
existing communication cord hole in the earcup from which it was removed. Carefully pull more
