Adjusting the Interpupillary Distance
The interpupillary distance, the distance
between 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 a distant object. Move the
two barrels (halves) of the binocular closer
together or further apart until you see a
single, clear image. Check that the
interpupillary distance is set correctly
every time you use your binocular.

Setting the Diopter / Focusing
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 STYRKA S3 Series features 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
better suit some users.

Tripod Adaptability
STYRKA S3 Series binoculars 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. 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
STYRKA S3 Series binoculars are waterproof and filled with dry nitrogen gas to prevent the housing from
fogging internally. This allows the binoculars to be used in all weather conditions.

Care and Storage
Your STYRKA binocular will provide you years of dependable service in the field if it is cared for
and stored properly.
5. Do not leave the binocular in a car on a hot/
sunny day or near anything that generates heat
as this may cause damage.
6. Clean any dust, dirt or water that may get on
the binocular or inside moving parts as soon
as possible to prevent any unforeseen damage.
1. Protect the binocular from impact and do not
force any of the moving parts beyond their limits.
2. Protect the optics of your binocular by putting
on all lens caps when not in use.
3. Store your binocular in a cool, dry place
whenever possible.
4. When storing for an extended period of time,
place the binocular in a plastic bag or airtight
container with a desiccant.

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. Using the Spudz microfiber cleaning cloth (included) remove
any fingerprints, stains or smudges from the lens surface 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.
