1.3. PRINCIPLES OF OPERATION
1.3.1. MECHANICAL FUNCTIONS
the mechanical functions of the nVMpS allow for differences in the
physical features of individual operators and provide for operating
the system. these functions include the power switch, eye relief
adjustment, diopter adjustment, gain control, and objective focus.
the mechanical controls are identified in Figure 1.5.
