Turn off NVD when not in use and
remove batteries for storage
Just remembering to do that will prevent the most common
NVD damage. If you leave your NVD on all the time, eventually
the image intensifier burns out. That costs $2K to replace. If
you’re not using your NVD, turn it off. And before you store
it, remove the batteries. That way the batteries can’t leak and
destroy the NVG’s electronics.
Check for battery cap lanyard during PMCS
Without the cap, the lens
gets scratched, the objective
lens housing is damaged and
the
image
intensifier
tube
burns out. New caps cost only
17 cents each, so order extras
The cap has a tab for attaching
a lanyard to keep it from
disappearing.
±
It doesn’t take much to
break
the
lanyard.
Once
the lanyard disappears, the
battery cap will soon follow.
And then your NVG is out of
business. Order a new lanyard
It costs only 33 cents, so keep
extras on hand.
Some units just etch the information into the NVG. Bad idea! That can damage the NVG. If
you need a new data label, contact CECOM’s Jenny Irizarry at DSN 648-1406, (443) 395-1406,
or email:
jenny.a.irizarry.civ@mail.mil
Provide her the sight’s NSN, how many labels are needed, whether the label is for the
sight itself or the sight case, and a valid shipping address. Normally, you’ll receive the labels
within a few days.
