3. Setup

3.1 Attaching the Neck Strap

1. Thread the ends of the neck strap through the strap lugs on each side of the binoculars.
2. Secure the strap by feeding it back through the buckle, ensuring it is tightly fastened.
3. Adjust the strap length for comfortable carrying around your neck.

3.2 Adjusting Interpupillary Distance (IPD)

The interpupillary distance is the distance between the centers of your pupils. Adjusting this correctly ensures a single, circular field of view.

1. Hold the binoculars with both hands.
2. Look through the binoculars at a distant object.
3. Bend the body of the binoculars at the hinge until you see a single, clear circular field.
4. Note the setting for future use.

3.3 Eyecup Adjustment

The eyecups can be adjusted for comfortable viewing, especially for eyeglass wearers.

• For non-eyeglass wearers: Extend the eyecups by twisting or pulling them up.
• For eyeglass wearers: Retract the eyecups by twisting or pushing them down to allow your eyes to be closer to the lenses, providing a full field of view.

4. Operating Instructions

4.1 Focusing Your Binoculars

Follow these steps to achieve a sharp image:

1. Step 1: Adjust Interpupillary Distance. Ensure the binoculars are adjusted for your eye width as described in Section 3.2.
2. Step 2: Focus the Left Eye. Close your right eye or cover the right objective lens. Look through the left eyepiece at a distant object. Rotate the central focus wheel until the image in the left barrel is sharp and clear.
3. Step 3: Focus the Right Eye (Diopter Adjustment). Close your left eye or cover the left objective lens. Look through the right eyepiece. Rotate the right eyepiece focus ring (diopter adjustment) until the image in the right barrel is sharp and clear.
4. Step 4: Fine-tuning. With both eyes open, use only the central focus wheel to adjust focus for different distances. The diopter setting should only need to be adjusted once for your eyes.

5. Maintenance and Care

5.1 Cleaning the Lenses

• Use a soft, lint-free cloth specifically designed for optical lenses.
• Gently brush off any dust or debris with a lens brush or compressed air.
• For stubborn smudges or fingerprints, apply a small amount of lens cleaning fluid to the cloth (not directly to the lens) and wipe gently in a circular motion.
• Avoid using abrasive cloths, paper towels, or harsh chemicals, as these can scratch or damage the lens coatings.

5.2 General Care and Storage

• Always replace lens caps when the binoculars are not in use to protect the lenses.
• Store the binoculars in their carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Avoid dropping or subjecting the binoculars to strong impacts.
• The binoculars feature a rubber coating for durability and grip.
• These binoculars are waterproof; however, avoid prolonged submersion. Dry thoroughly if they get wet.

6. Troubleshooting

• Blurry Image:
  • Ensure the central focus wheel and diopter adjustment are correctly set for your eyes and the viewing distance.
  • Check if the objective lenses or eyepieces are dirty and clean them as per Section 5.1.
• Double Image or Two Circles:
  • Adjust the interpupillary distance (distance between the barrels) until a single, circular field of view is achieved (refer to Section 3.2).
• Difficulty Focusing:
  • Ensure eyecups are correctly positioned for your viewing preference (with or without eyeglasses).
  • Re-perform the focusing steps (Section 4.1) carefully.
