8x36RF has a built-in step rangefinder with a mils
scale for distance, angle and height detection.
dIStance
If the height of a
viewed object is
known, use the fol-
l o w i n g e q u a t i o n
substituting height
of object for vari-
able H:
L = H/MILS x 1000
anGLe
To c al c ulate the
included angle of a
viewed object, use the following formula:
x° = 0.06 x MILS
HeIGHt
If the distance to a viewed object is known, use
the following equation substituting distance to
object for variable L:
H = L x MILS/1000
2M tarGet BaSed ScaLe
A 2m target fits between the numbered baseline
and the main horizontal line. If the 2m target fits
between the 4 and the right horizontal post of the
main line the target is 400 m away. If the same
target fits between the 7 and the right post of main
line the target is 700 m away.
CarE and CLEanInG
By following these simple guidelines, your
binocular will provide optimal performance for
many years:
1. Keep binocular lenses clean and free of
moisture and dirt.
2. When not in use, do not expose your binocu-
lars to direct sunlight for long periods of time
(e.g. on the dashboard of your vehicle).
3. Store your binocular in a cool, dry place.
Always store your binocular in its carrying
case, with the rubber roll-down eyecups in the
“up” position.
4. Binoculars are precision instruments -
handle them with care. Do not drop, shake,
bump or rattle your binocular. Its precision
optics can become misaligned (out of collima-
tion) as a result of rough treatment, which can
render the instrument virtually unusable.
Collimation problems usually require repair by
a trained technician, and are generally not cov-
ered by the Warranty.
To clean your binocular, follow these simple
steps:
1. Before attempting to clean any of the lenses,
carefully remove all grit, sand, dirt, dust, or
other substances which may scratch the sur-
face of the optics. Avoid touching lens surfaces
with fingers or coarse materials. Use a soft lens
brush, lens cleaning tissue, a lint-free cotton
cloth, a clean cotton swab, or “canned” air.
2. For materials that remain on the lenses, use
a liquid substance designed to remove grease
(e.g., commercial lens cleaner, household
window cleaner or rubbing alcohol).
CAUTION: Do not apply liquid directly onto a
lens, which may result in the liquid seeping into
the barrel of the binocular. Apply the solution
onto a cloth or swab, and use the cloth or swab
to remove the foreign substance with circular
motions. Take care as to not rub away antire-
flectant lens coatings. Use a light touch.
If a 2m target fits
between these two
lines then the target
is 400m away.
If a 2m target fits
between these two
lines then the target is
700m away.
