5. Operating Instructions
5.1 Focusing the Binoculars
Follow these steps to achieve a clear and sharp image:

Image 5.1: Step-by-step guide to focusing your binoculars.
- Step 1: Adjust Interpupillary Distance. Make sure the distance between the two barrels is between your eyes, as described in Section 4.1.
- Step 2: Focus Left Eye. Close your right eye. Look through the left eyepiece and rotate the center focusing wheel until the image appears sharply focused.
- Step 3: Focus Right Eye (Diopter Adjustment). Close your left eye. Look through the right eyepiece and rotate the eyepiece focus ring (diopter ring) until the image appears sharply focused.
Once both eyes are individually focused, you can use the center focusing wheel for quick adjustments to objects at different distances.
5.2 Using with Smartphone Adapter
After attaching the phone adapter as described in Section 4.3:
- Open your smartphone's camera application.
- Adjust the phone's position on the adapter until the binocular's field of view is centered and fills your phone screen. You may need to zoom in slightly on your phone's camera to eliminate vignetting (dark edges).
- Use the binocular's focusing mechanisms (center wheel and diopter) to achieve a clear image on your phone screen.
- Capture photos or videos as desired using your phone's camera controls.
6. Maintenance
6.1 Cleaning the Lenses
To maintain optical clarity, clean the lenses carefully:
- Gently brush off any dust or loose debris from the lenses using a soft lens brush or compressed air.
- Apply a small amount of lens cleaning fluid to the included cleaning cloth.
- Wipe the lenses in a circular motion, starting from the center and moving outwards. Avoid excessive pressure.
- Do not use abrasive cloths, paper towels, or household cleaners, as these can scratch or damage the lens coatings.
6.2 Storage
When not in use, store your binoculars in the dedicated carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the lens caps are in place to protect the objective and eyepiece lenses.
6.3 Waterproofing
The Jivcok 300x25 Binoculars feature IPX7 waterproofing, meaning they are protected against immersion in water up to 1 meter for 30 minutes. While they are designed to withstand various weather conditions, avoid prolonged submersion or exposing them to high-pressure water jets.

7. Troubleshooting
If you encounter issues with your binoculars, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Image is blurry or out of focus. | Incorrect focus adjustment. | Re-adjust the center focusing wheel and diopter ring as per Section 5.1. |
| Dark edges or two overlapping circles in the view. | Interpupillary distance not set correctly. | Adjust the barrel distance until a single, clear circular field of view is achieved (Section 4.1). |
| Image appears dim or unclear. | Lenses are dirty or smudged. | Clean the objective and eyepiece lenses carefully (Section 6.1). |
| Difficulty aligning phone camera with binoculars. | Phone not securely mounted or misaligned. | Ensure phone is firmly in the holder and carefully adjust its position to align with the eyepiece. Zoom in slightly on your phone's camera if necessary. |
