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
Eyecup Adjustment
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.

The STYRKA S7 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 fi eld of view. The eyecups can be set at positions between fully up and down which may better suit some users.

Tripod Adaptability
Care and Storage
STYRKA S7 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 S7 Series binoculars are waterproof and fi lled with dry nitrogen gas to prevent the housing from fogging internally. This allows the binoculars to be used in all weather conditions.

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 microfi ber cleaning cloth (included) remove any fi ngerprints, 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.
