• For users without eyeglasses: Twist the eyecups counter-clockwise until they are fully extended. This positions your eyes at the optimal distance from the eyepieces.
• For users with eyeglasses: Twist the eyecups clockwise until they are fully retracted. This allows your eyeglasses to be closer to the eyepieces, providing a full field of view.

3.3 Interpupillary Distance Adjustment

The interpupillary distance (the distance between your pupils) varies among individuals. To adjust:

1. Hold the binoculars with both hands and look through them.
2. Bend the binocular body at the hinge until you see a single, clear circular field of view.

3.4 Focusing the Binoculars

To achieve a sharp image:

1. Close your right eye and look through the left eyepiece. Rotate the central focusing wheel until the image is sharp.
2. Close your left eye and look through the right eyepiece. Rotate the diopter adjustment ring (located on the right eyepiece) until the image is sharp.
3. Now, with both eyes open, use only the central focusing wheel to focus on objects at varying distances. The diopter setting should remain constant for your vision.

3.5 Using the Phone Adapter

The included phone adapter allows you to capture photos and videos through the binoculars.

1. Attach the phone adapter to one of the binocular eyepieces.
2. Secure your smartphone into the adapter, ensuring the phone's camera lens is aligned with the binocular eyepiece.
3. Adjust the phone's position and zoom to eliminate vignetting and achieve a full view.
4. Use your phone's camera app to capture images or record videos.

• Screw the binocular tripod adapter into this socket.
• Attach the adapter to your tripod's quick-release plate or mounting screw.

4. Optical Features and Performance

4.1 BAK4 Prisms

These binoculars utilize BAK4 (Barium Crown Glass) roof prisms. BAK4 prisms are known for their high refractive index and produce nearly perfect circular exit pupils, resulting in brighter, clearer, and sharper images with increased contrast and resolution compared to less expensive BK7 prisms.

4.2 Fully Multi-Coated (FMC) Lenses

The 42mm objective lenses are Fully Multi-Coated (FMC). This means multiple layers of anti-reflective coatings are applied to all air-to-glass surfaces. FMC lenses significantly reduce light loss and glare, enhancing light transmission for brighter, higher-contrast images with true-to-life color fidelity, especially in low-light conditions.

4.3 Tšimo ea View and Close Focus

These binoculars offer a wide field of view of 388ft/1000yds, allowing for efficient observation of large areas. The close focus distance of 6.5 feet enables detailed viewing of nearby subjects.

2. Apply a small amount of lens cleaning fluid to the included cleaning cloth or a specialized optical cleaning cloth.
3. Wipe the lens surfaces in a circular motion, starting from the center and moving outwards. Avoid excessive pressure.
4. Do not use abrasive cloths, paper towels, or household cleaners, as these can scratch or damage the lens coatings.

5.2 Waterproof and Fogproof Design

The binoculars are IPX7 waterproof, meaning they can withstand immersion in water up to 1.5 meters for 30 minutes. They are also dry nitrogen-filled and O-ring sealed to prevent internal fogging in varying temperatures and humid conditions. While designed for durability in harsh environments, avoid unnecessary exposure to extreme conditions.
