Other Extreme Conditions
HIGH HUMIDITY OR SALTY CONDITIONS
(1) Avoid exposing the binocular to direct salt spray. Salt
water is extremely corrosive and can cause irreparable
damage to the binocular.
(2) Always dry the binocular thoroughly after use and
immediately clean lens as per “Cleaning Instructions“
and install objective and eye lens covers.
SAND AND DUST
(1) Always keep the binocular objective and eye lens
covers on when not actually in use. Sand and
dust will etch glass surfaces and can penetrate
through the smallest openings, thereby causing
damage to adjusting mechanisms.
(2) Upon completion of operations, remove all
particles of sand and dust from optical elements
as per “Cleaning Instructions“ before installing
protective objective and eye lens covers.
