2. Adjusting Interpupillary Distance

Hold the binocular with both hands and look through the eyepieces. Adjust the distance between the two barrels until you see a single, circular field of view. This ensures proper alignment with your eyes.

3. Adjusting Eyecups

The Sportstar EX features turn-and-slide rubber eyecups. If you wear eyeglasses, rotate the eyecups down to their lowest position. If you do not wear eyeglasses, rotate the eyecups up to a comfortable position that allows you to see the full field of view without vignetting.

4. Diopter Adjustment

This adjustment compensates for differences in vision between your left and right eyes.

1. Close your right eye or cover the right objective lens.
2. Look through the left eyepiece with your left eye and rotate the center focus wheel until the image is sharp.
3. Close your left eye or cover the left objective lens.
4. Look through the right eyepiece with your right eye and rotate the diopter adjustment ring (usually on the right eyepiece) until the image is sharp. Do not use the center focus wheel for this step.
5. With both eyes open, the image should now be sharp. From this point forward, use only the center focus wheel for focusing on different distances.

Operating the Binocular

Focusing

Once the interpupillary distance and diopter are set, focusing on objects at various distances is straightforward:

1. Bring the binocular to your eyes.
2. Locate the object you wish to view.
3. Rotate the center focus wheel until the image appears sharp and clear.

General Usage Tips

• Steady Viewing: For prolonged viewing, try to brace your elbows against your body or a stable surface to minimize hand shake.
• Low Light Conditions: While the multilayer-coated lenses enhance brightness, avoid using the binocular in extremely dark conditions where visibility is already minimal.
• Eye Relief: The turn-and-slide eyecups allow for comfortable viewing whether you wear glasses or not. Adjust them to achieve the optimal eye relief.

Maintenance

Cleaning Lenses

To clean the lenses, first gently brush off any dust or debris with a soft lens brush or blow it off with a can of compressed air. Then, use the provided cleaning cloth or a clean, soft cotton cloth, slightly moistened with lens cleaning fluid, to wipe the lenses in a circular motion. Avoid using harsh chemicals or abrasive materials, as these can damage the lens coatings.

Cleaning the Body

Wipe the binocular body with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by wiping with a clean, damp cloth. Ensure no water enters the optical components.

Storage

When not in use, store the binocular in its protective case in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid storing it in areas with high humidity to prevent mold growth on the lenses.

Waterproof and Fog-Free Features

The Nikon Sportstar EX is waterproof and fog-free, thanks to nitrogen gas purging. While it is designed to withstand various weather conditions, avoid submerging it in water or exposing it to prolonged heavy rain. If the binocular gets wet, wipe it dry with a soft cloth as soon as possible.
