The interpupillary distance, or the distance
between the pupils, varies from person to
person. The binocular must be correctly aligned
(adjusted) to the distance between your pupils
to achieve a single, clear image. To adjust this
distance, lift the binocular up to your eyes (using
both hands) and look through them at an object
in the distance. Move the two barrels (halves)
of the binocular closer together or further
apart until you see a single, clear image (Fig. 2).
Check that the interpupillary distance is set
correctly every time you use your binocular.

To ensure a crisp, sharp image the focusing
system of the binocular must be set to
compensate for any differences in your
eyesight. This is achieved by setting the diopter
(located on the right eyepiece) before use. To
set the binocular to your eyesight follow the
instructions below.
1. View an object in the distance through the
binocular.
2. Cover the right objective lens with your hand
or the objective lens cap.
3. Rotate the focus wheel until the image
viewed with your left eye is clear and sharp.
4. Cover the left objective lens with your hand
or objective lens cap.
5. Viewing the same object, adjust the diopter
ring until the image viewed with your right
eye is clear and sharp.
6. Your binocular is now adjusted to your eyes
and focusing on any object can now be
achieved by simply turning the focus wheel.
TIP: Eyeglasses worn for nearsightedness should be worn when using
binoculars as you may not be able to obtain focus at infinity
without them.

EYECUP ADJUSTMENT
The Nature DX binoculars feature twist-up
eyecups to accommodate both eyeglass and
non-eyeglass wearers. If you do not wear
eyeglasses, twist the eyecups counterclockwise
until they reach the up position. If you wear
eyeglasses, make sure that the eyecups are in
the down position to obtain the maximum field
of view. The eyecups can be set at positions
between fully up and down which may suit
some users better.

TRIPOD ADAPTABILITY
The 32 mm and 42 mm versions of the Nature
DX binocular series feature built-in threads that
allow the binocular to be attached to a tripod
using a binocular tripod adapter. These threads
can be accessed by unscrewing the logo plate
found on the front of the hinge (Fig. 5).
To attach the binocular to a tripod, thread the
adapter into the binocular and attach the other
end of the adapter to a photographic tripod.
Mounting the binocular on a tripod allows for
added stability and comfort during prolonged
viewing.

WATERPROOF / FOGPROOF
The Nature DX series binoculars are waterproof
and filled with dry nitrogen gas to prevent the
housing from fogging internally.

CLEANING
Proper cleaning of the lenses is essential
to maintaining the optical integrity of your
binocular. Dirty lenses diminish the amount of
light transmitted through the binocular and your
overall viewing experience.
1. Remove any dust on the lenses with a soft
lens brush or can of pressurized air.
2. Remove any fingerprints, stains or smudges
from the lens surface with a soft, clean lens
cloth or lens tissue by rubbing in a circular
motion. Start in the middle of the lens and
work your way to the edges. Breathe lightly
on the lens to provide moisture if needed.
3. For a more thorough cleaning we recommend
the use of a lens/optics cleaning kit available
at most photo or optical shops. Follow the
directions supplied with the cleaning kit for
best results.
