B. MECHANICAL FUNCTIONS
the mechanical functions of the atn nVM-14 allow for dif-
ferences in the physical features of individual operators and
provide for the system operation. these functions include the
On/Off/On IR control, eye relief (Section III Mounting proce-
dures),
diopter adjustment, objective lens focus, and IR illu-
minator focusing. these mechanical controls are identified in
Figure 4-3.
