Extreme Cold / Extreme Heat
EXTREME COLD
(1) Avoid breathing directly on the optical ele-
ments of the binocular. The breath may
condense and freeze.
(2) Do not expose the binocular to sudden and
extreme temperature changes, such as car-
rying it directly from a well-heated area into
sub-zero temperatures. Extreme tempera-
ture changes may cause the optical ele-
ments to crack.
EXTREME HEAT
(1) Do not allow the binocular to lie unprotected from
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 airconditioned
area. This will permit the binocular to cool down
gradually and prevent condensation from forming.
