If the cushioning has other dents, es-
pecially in the non-cutout area, you’re
packing it wrong. The carrying case
won’t fit properly in the shipping and
storage case and eventually the
headmount will break.
Before you pack, make sure the
goggle assembly is free of dirt, dust
and moisture. If it’s not, clean it with a
clean, lint-free cloth. Clean the optical
surfaces, including the sacrificial win-
dow assembly and the eyecups with

clean water and lens paper. Don’t use
water on the demist shields. Water ru-
ins them. Use only dry lens paper to
clean them.
Don’t forget to clean the carrying
case. Shake out the case and knock it
on your leg to loosen and remove dirt
and dust. Wipe the case, inside and
out, with a dry lint-free cloth.
For stubborn dirt, dampen the lint-
free cloth with clean water and, if
needed, a mild detergent. Just make
sure the case is thoroughly dry before
you pack the goggle assembly. Let the
case air dry. Direct sunlight will fade
and shrink it.
Once you have a
clean assembly and
carrying case, pack
the case like this:
1.
Put the demist
shields and batteries
into their labeled
pockets.
2.
Unsnap and re-
move the shallow
pocket inside the car-
rying case. This
gives you easier ac-
cess to the back
pocket.

our AN/PVS-7B night vision
goggles must be packed and stored cor-
rectly. If not, you’ll crack or break the
harness of the headmount assembly.
So check the foam cushioning in the
lid of the shipping and storage case.
If the cushioning has a slight dent in
the middle of the cutout area, you’re
OK. That dent is caused by the
headmount socket assembly. It tells you
that you’re packing the assembly right.
