EXTREME COLD
(1) Avoid breathing directly on the optical elements
of the binocular. The breath may condense
and freeze.
(2) Do not expose the binocular to sudden and
extreme temperature changes, such as
carrying it directly from a well-heated area into
subzero temperatures. Extreme temperature
changes may cause the optical elements to crack
EXTREME HEAT
(1) Do not allow the binocular lo lie unprotected
in the direct rays of the sun. The intensified
heat may damage the binocular mechanisms.
(2) Place the binocular objective and eye-lens covers
on the binocular before entering an air conditioned
area. This will permit the binocular to cool down
gradually and prevent condensation from forming.
