Maintenance Tips

• Clean lenses gently: Use a microfiber cloth and lens-safe cleaner to preserve HD clarity and protect multi-coated optics.
• Keep lens covers on: Prevent dust, dirt, and scratches when not in use.
• Avoid touching glass: Fingerprints reduce brightness and image sharpness—handle by the body only.
• Maintain focus wheel & diopter: Keep controls free of debris for smooth focusing and precise eye adjustment.
• Check hinge tension: Ensure interpupillary distance stays firm for stable, comfortable viewing.
• Dry after exposure: Even though waterproof and fogproof, wipe down after rain or humidity.
• Store properly: Keep in a protective case in a cool, dry place to extend lifespan.
• Avoid impacts: Rubber-armored body is durable, but minimizing drops helps maintain optical alignment.
