Blury
Vision?
I
s the view through your Bradley’s integrated sight unit (ISU) blurry? Most
operators assume that the ISU needs to be purged and charged with nitrogen to get
rid of condensation inside the unit.
But the solution could be
simpler. First, try turning
on the ISU defogger fan.

by condensation outside
the unit, that usually takes
care of it.

the windows on the ISU’s
doghouse
assembly
are
dirty. You can’t just grab
a paper towel and some
glass cleaner, though. The
ISU glass has a special
coating on it. If you clean
it wrong, the coating is
damaged and your ability
to see just got worse.
1.
Rinse the window with clean water from a squirt bottle
until all loose particles are gone. Warm water works best.

3.
Flush off the cleaning solution with clean water.
4.
Dry the windows by wiping lightly in a single direction
with clean lens tissue.
2.
Soak a lens tissue, NSN 6640-00-436-5000, in lens cleaning
solution, NSN 6850-00-227-1887, and clean the window
with light pressure. Wipe in a single direction. Wiping
in multiple directions is a good way to smear the glass and
increases the chance of scratching it.
