(g) Position the helmet so that the right rear side is facing you.
(h) Check the size of the helmet.
(i) Depending upon the helmet size, position one of the four large holes along the top
of the template over the right rear retention screw (located next to the eardome) as in Figure 3.
Note
Ensure that the template follows the contour of the helmet shell.
(j) Align the curve at the bottom of the template with the helmet shell edge beading.
If the helmet has a cap plug align the curve on the left side of the template with the cap plug.
(k) Depending upon the helmet size, select the hole to be drilled. Using a pencil or
an awl, mark the location of the hole to be drilled, in the shell, through the template hole labeled
DRILL CENTER MARK. Verify that the point located on the right side of the helmet, is one inch
above the cut line, and is midway on the flat plane of the transition between the sphere of the
helmet and the earcup dome.
