General
This section contains unit maintenance level procedures for
servicing and inspecting minor assemblies of the lightweight digital
facsimile. The maintenance functions (such as inspection and servicing)
are described in Appendix B, Maintenance Allocation Chart, paragraph B-2,

The front cover assembly is removed by
unlatching, swinging up, opening, and removing from the LDF by releasing
the two hinge pins (see Figure 1).
