Operating the Reflex Sight
Red Dot Illumination:
The NV Sight II LE features automatic control of the illuminated dot intensity. The brightness of the red dot adjusts automatically to ambient light conditions, ensuring optimal visibility without manual intervention. This auto-adjustment feature helps maintain a clear and bright aiming point in various lighting scenarios.
Parallax-Free Operation:
The sight is set to be parallax-free at 40 meters. This means that within this range, the red dot will remain on target regardless of minor head movements or eye position, providing consistent accuracy.
Aiming and Target Acquisition:
Utilize the sight with both eyes open for maximum situational awareness and faster target acquisition. The clear, distortion-free image provided by the optical system aids in quick and precise aiming.
Adjustments:
Use the provided adjusting wrench with its specific scale for any necessary windage and elevation adjustments. Make small, incremental adjustments and verify zero after each change.
Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your NOBLEX NV Sight II LE.
Cleaning the Lenses:
Use the provided cleaning cloth to gently wipe the lenses. For stubborn smudges, a small amount of lens cleaning solution designed for optical surfaces can be applied to the cloth, not directly to the lens. Avoid using abrasive materials or harsh chemicals that could damage the coatings.
Battery Replacement:
When the red dot illumination appears dim or inconsistent, it may be time to replace the CR 2032 lithium battery. Refer to the battery compartment for specific instructions on replacement, ensuring correct polarity.
Storage:
Store the sight in a dry, cool place, away from direct sunlight and extreme temperatures. Use the protective cap when the sight is not in use to prevent dust and scratches.
Environmental Considerations:
The sight is designed to drain accumulated water quickly in extreme weather. After exposure to moisture, ensure the sight is thoroughly dried before storage.
Troubleshooting
This section addresses common issues you might encounter with your NOBLEX NV Sight II LE. For more complex problems, please contact customer support.
Red Dot Not Visible or Dim:
- Check Battery: Ensure the CR 2032 battery is correctly inserted and has sufficient charge. Replace if necessary.
- Clean Lens: A dirty lens can obscure the red dot. Clean the lens gently with the provided cloth.
- Ambient Light: While the sight has auto-adjusting brightness, extremely bright or dark conditions might affect initial visibility. Allow the sensor to adjust.
Inaccurate Aiming:
- Mounting Stability: Verify that the sight is securely mounted to your weapon. Loose screws can cause inconsistencies.
- Zeroing: Ensure the sight has been properly zeroed for your specific weapon and ammunition at the desired distance. Re-zero if accuracy issues persist.
- Parallax: Remember the sight is parallax-free at 40 meters. At significantly different distances, minor parallax might be observed.
Physical Damage:
If the sight sustains physical damage, do not attempt to repair it yourself. Contact NOBLEX customer support or an authorized service center.
