CAUTION
• Do not touch any optical surfaces. Anything
on your hands that gets on optical surfaces
will cause an unwanted cleaning task.
Cleaning too often will wear away coating on
optical surfaces.
• The PNVS shroud assembly window and
housing are fragile and easily broken or
damaged beyond AVIM repair capabilities.
Use extreme care when handling the PNVS
shroud assembly to prevent dropping or
jarring the assembly.
1. Check position of NSA (1). NSA is properly
positioned when elevation mirror assembly (2)
is facing about 90° to the left of forward
position. If required, position NSA using
procedures in paragraph 3-3.
2. Have NSA exposed optics (2) (para 3-7)
inspected. If directed, clean exposed optics
(para 3-8).
