3.2 INSPECTION / CLEANING - Continued
Battery Cap
Inspect the battery cap for dirt, sand, and grime. Thoroughly
clean the battery cap and o-ring by flushing with water and
wiping with a cotton swab. Periodically lubricate the o-ring
with fluorinated grease. If necessary, clean the battery
contact with a cotton swab and isopropyl alcohol.
Optical Surfaces
CAUTION
The coating on the demist shield may be damaged
if cleaned while wet. Clean the demist shield only
when dry and using dry lens tissue.
Inspect optical surfaces for dirt, dust, and grime. Except for
the demist shield, clean with water or mild soap and water.
Fine cleaning of the optical surfaces should be performed
using the provided lens tissue and lens cleaning solution, or
the flexible tip of the lens pen. Avoid using excessive force
as this may scratch the lenses. The sacrificial window and
demist shield should be replaced if scratches degrade
performance or cracks are present.
Neck Cord
Inspect the neck cord for any signs of cuts, nicks, or fraying.
Replace as necessary per section 3.3, Lens Cover / Neck
Cord Replacement.
