headmount assembly over the head.
5. Remove slack from the two rear chin straps but do not
tighten.
6. Adjust front and rear chin straps and vertical adjustment

NOTE
Minor strap adjustments may be necessary after
installing the headmount adapter and MNVD.
Headmount Adapter
The headmount adapter allows the MNVD to be installed on
the headmount assembly or a suitably configured helmet.
1. With the MNVD in one hand, use the free hand to orient
the headmount adapter above the mounting interface as
shown in Figure 2-4. Keying features in the headmount
adapter and mounting interface allow only one
orientation.
2. Rotate the thumbscrew clockwise to secure the
headmount adapter to the MNVD, taking care not the
cross threads.
