5. Operación de sus binoculares
5.1. Ajuste de la distancia interpupilar (DPI)
The interpupillary distance is the distance between the centers of your pupils. Adjusting this correctly ensures you see a single, clear circular field of view.
- Sujete los binoculares con ambas manos y mire a través de los oculares.
- Bend the binocular body at the hinge until you see a single, perfectly round field of view.
5.2. Enfoque
Your binocular features a central focus wheel and a diopter adjustment for precise focusing.
- Ajuste de dioptría: Cierre el ojo derecho y mire por el ocular izquierdo. Gire la rueda de enfoque central hasta que la imagen sea nítida y clara.
- Diopter Correction: Cierre el ojo izquierdo y mire por el ocular derecho. Gire el anillo de ajuste dióptrico (normalmente en el ocular derecho) hasta que la imagen sea nítida y clara.
- Now, with both eyes open, use only the central focus wheel to focus on objects at varying distances. The diopter setting should remain constant for your eyes.
5.3. Uso de la función Zoom
The Gladiator series allows you to change magnification levels seamlessly.
- Locate the zoom lever, typically near the right eyepiece.
- To decrease magnification (zoom out), move the lever towards the lower power setting.
- To increase magnification (zoom in), move the lever towards the higher power setting.
- Refocus slightly with the central focus wheel after changing the zoom level, as the focal point may shift.

5.4. ViewConsejos para principiantes
- For best results, especially at higher magnifications, use a tripod to stabilize the view.
- Start at the lowest magnification (20x) to locate your subject, then zoom in for more detail.
- Avoid rapid movements when observing at high magnifications.
6. Cuidado y mantenimiento
6.1. Limpieza de lentes
- Use the included lens cloth or a soft, lint-free cloth specifically designed for optics.
- Gently brush away any dust or debris from the lens surface.
- If necessary, use a small amount of optical lens cleaning fluid applied to the cloth, not directly to the lens.
- Wipe the lens in a circular motion, starting from the center and moving outwards.
- Evite utilizar paños abrasivos, toallas de papel o limpiadores domésticos, ya que pueden rayar o dañar los revestimientos de las lentes.
6.2. Cuidado general y almacenamiento
- Store your binoculars in the provided carrying case when not in use to protect them from dust, moisture, and impacts.
- Keep the lens caps on when storing.
- Avoid exposing the binoculars to extreme temperatures or sudden temperature changes.
- Do not attempt to disassemble the binoculars, as this will void the warranty and may cause irreparable damage.
